Description

Technical Field

[0001] The present invention relates to the technical field of wireless device testing, and in particular to a wireless device production line testing method, a wireless device, a tester, a testing system and a computer-readable storage medium. Background Art

[0002] Microphones and speakers are paired products. For microphones and speakers from the same manufacturer (or the same model), a paired connection mode is often used, that is, the connection broadcast signal sent by the microphone contains characteristic information that can only be recognized by speakers from the same manufacturer. Once the speaker recognizes the characteristic information, it immediately initiates the automatic pairing and connection process, and the pairing and connection can be completed without user operation. The pairing of microphones and speakers from the same manufacturer is random pairing, that is, although microphones and speakers are paired one by one, for a single microphone, there is no dedicated paired speaker for the microphone. As long as any speaker can recognize the above characteristic information, the microphone and speaker can be paired. If there is a microphone and multiple speakers in the same scene, then after the microphone is turned on, it will be randomly paired with one of the multiple speakers (often the first to identify, the first to connect).

[0003] In the production process of existing microphones, a microphone test station will be arranged on the production line. Please refer to Figure 1 , there is a speaker for testing the microphone on the test station (such as speaker 1 in the attached figure). Since the manufacturer may arrange the production lines of microphones and speakers in the same factory at the same time, not only speaker 1 on the test station can receive the connection broadcast signal of the tested microphone, but also the speaker that has been assembled on another production line (such as speaker 2 in the attached figure) can receive the connection broadcast signal of the tested microphone. Therefore, in the actual production test process, it is easy to make a wrong connection, thereby affecting the efficiency and accuracy of the microphone test. Summary of the invention

[0043] The present invention is described below based on embodiments, but the present invention is not limited to these embodiments. In the following detailed description of the present invention, some specific details are described in detail. In order to avoid confusing the essence of the present invention, known methods, processes, procedures, and components are not described in detail.

[0044] In addition, persons of ordinary skill in the art will appreciate that the drawings provided herein are for illustration purposes and are not necessarily drawn to scale.

[0045] Unless the context clearly requires otherwise, throughout the specification and claims, the words "include", "comprising" and similar words should be interpreted in an inclusive sense rather than an exclusive or exhaustive sense; that is, in the sense of "including but not limited to".

[0046] In the description of the present invention, it should be understood that the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0047] As described above, when a wireless device is undergoing production testing, it is susceptible to interference from nearby pairable devices, resulting in misconnection, which affects the efficiency and accuracy of the test. In view of this, an embodiment of the present invention proposes a wireless device production line testing method, which enters a production test boot state when the wireless device is turned on to seek a test connection to avoid interference from other pairable devices.

[0048] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0049] Figure 2 A flow chart showing a method for testing a wireless device production line according to an embodiment of the present invention is shown in FIG. Figure 2 An embodiment of the wireless device production line testing method in the embodiment of the present invention includes: steps S1 to S5.

[0050] In step S1, when the first wireless device is turned on, the production test guidance state is entered. Specifically, the production test guidance state is a working state in which the wireless device guides the test device to establish a production test connection with the wireless device by sending a production test broadcast signal within a set time. In an embodiment of the present invention, the set time is a first time period, and illustratively, the first time period can be set to 500 milliseconds. In actual applications, the specific duration of the first time period can be determined according to the actual production environment and test conditions, and is not limited here.

[0051] In the embodiment of the present invention, the first wireless device is a wireless device to be tested, which can be an electronic device such as a microphone, a speaker or a headset that has a wireless transmission function and needs to be paired for use. The test device is an electronic device that has the function of establishing a pairing connection with the first wireless device and can identify test feature information. The production test connection in the embodiment of the present invention is a special pairing connection used for production line testing.

[0052] In step S2, the first wireless device sends a first production test broadcast signal within a first time period, the first time period being the duration of the first wireless device in the production test guidance state, the first production test broadcast signal being used to guide the test device to establish a production test connection with the first wireless device, and the first production test broadcast signal having test feature information for identification by the test device. Exemplarily, the test feature information may be at least one of the following: a message name of the broadcast signal, a pairing code of the broadcast signal, and a message content of the broadcast signal.

[0053] In an embodiment of the present invention, the first production test broadcast signal can be a broadcast signal in the wireless Bluetooth protocol, and its operating frequency band can be a 2.4G frequency band, or it can be a broadcast signal in other general wireless communication protocols or private wireless communication protocols. The protocol type of the broadcast signal can depend on the specific application scenario and is not limited here.

[0054] In step S3, the first wireless device monitors a first production test connection signal within a first time period, where the first production test connection signal is a production test connection request signal sent by the test device in response to the first production test broadcast signal.

[0055] Exemplarily, in an actual production line test scenario, the test equipment can be set at a test station at the end of the production line of the first wireless device. After a first wireless device is assembled, it is transmitted to the test station along the assembly line. After the tester turns on the first wireless device, the first wireless device sends a first production test broadcast signal within a first time period. At this time, the test equipment located at the test station is in a listening state and can listen to the broadcast signals around it. When the test equipment listens to a broadcast signal, it immediately identifies its broadcast message information. If the test feature information is identified, it confirms that the broadcast signal is a first production test broadcast signal, and further parses the first production test broadcast signal to obtain the address information of the first wireless device, and sends a first production test connection signal to the first wireless device based on the address information to request to establish a production test connection with the first wireless device.

[0056] In step S4, if the first production test connection signal is monitored, the first wireless device establishes a production test connection with the test device in response to a request of the first production test connection signal.

[0057] Exemplarily, the establishment of a production test connection between a first wireless device and a test device is described in a communication scenario under the Bluetooth Low Energy (BLE) protocol. When the test device recognizes the first production test broadcast signal, it will initiate a request to establish a production test connection to the first wireless device according to the address information carried in the first production test broadcast signal (i.e., send a first production test connection signal). Among them, the first production test connection signal carries "information on which time period and which physical frequency band to send and receive data after the production test connection is established". After the first wireless device receives the first production test connection signal and successfully parses the first production test connection signal, the first wireless device enters the production test connection state, and can interact with the test device in the agreed time period and agreed physical frequency band. In the BLE protocol, after sending the first production test connection signal, the test device can switch to the production test connection state without waiting for the response of the first wireless device. When the first wireless device successfully interacts with the test device in the agreed time period and agreed physical frequency band for the first time, the test device can confirm that the production test connection is successfully established.

[0058] In step S5, a function test is performed on the first wireless device in the production test connection state.

[0059] Exemplarily, it is assumed that the first wireless device is a microphone, the test device is an electronic device with a wireless transmission function and an audio playback function, and the functional test to be performed is the audio link function of the microphone (such as a pickup function test). The tester turns on the microphone, waits for a period of time, and observes whether the microphone and the test device have established a production test connection. For example, the microphone and the test device are respectively provided with connection indicator lights, and the signal displayed by the connection indicator light (such as whether the light is on, or whether the red light or the green light is displayed) indicates whether the microphone and the test device are in a connected state. After confirming that the microphone and the test device have established a production test connection, the tester speaks to the microphone, and the microphone can collect audio signals through the microphone and transmit the audio signals to the test device through the physical frequency band agreed by the production test connection. If the test device can play the tester's speech audio normally, it is confirmed that the pickup function of the microphone is normal. If the test device cannot play the tester's speech audio normally (including unclear audio playback or no audio playback at all), it is confirmed that the pickup function of the first wireless device is abnormal.

[0060] Furthermore, if the first wireless device completes the functional test in the production test connection state, the current state of the first wireless device is updated to the waiting for pairing state, and can normally perform ordinary pairing connection with other wireless devices.

[0061] In the embodiment of the present invention, when the first wireless device is turned on, it immediately enters the production test guidance state and sends a first production test broadcast signal, wherein the first production test broadcast signal has test feature information that is only recognized by the test device. After the test device receives the first production test broadcast signal, it feeds back a first production test connection signal to the first wireless device to request to establish a production test connection and complete the corresponding functional test. In the production test guidance state, the first wireless device will not send broadcast information seeking a pairing connection, but will send the first production test broadcast signal that can only be recognized by the test device. Therefore, the first wireless device will not be interfered by other nearby pairable devices in the production test guidance state, thereby improving the success rate of the first wireless device and the test device in establishing a production test connection, thereby improving the efficiency and accuracy of wireless device testing.

[0062] In actual applications, the following situations may occur, resulting in failure to establish a production test connection within the first time period:

[0063] 1. The test device is not currently within the effective connection range of the first wireless device;

[0064] 2. The first wireless device and the test device are interfered by metal obstacles;

[0065] 3. The first wireless device incorrectly analyzes the first production test connection signal.

[0066] It should be noted that, in addition to the above-mentioned situations, other factors may also cause the production test connection to fail to be established within the first time period. This is only an exemplary description and does not exhaustively list all situations.

[0067] The embodiment of the present invention proposes a corresponding solution to the above situation where the production test connection cannot be established in the production test guidance state. Figure 3 , Figure 3 Another flow chart of the wireless device production line testing method in the embodiment of the present invention is shown. Another embodiment of the wireless device production line testing method in the embodiment of the present invention includes: step T1 to step T12.

[0068] Steps T1 to T2 in the embodiment of the present invention are consistent with steps S1 to S2 in the above embodiment, and are not described again here.

[0069] In step T3, the first wireless device monitors the first production test connection signal in the first time period. If the first production test connection signal is not monitored in the first time period, step T5 is executed.

[0070] In step T4, if the first production test connection signal is monitored, in response to the request of the first production test connection signal, the first wireless device establishes a production test connection with the test device, updates the current state of the first wireless device to the production test connection state, and executes step T12 to perform a functional test. If the first production test connection signal is incorrect, resulting in a timeout in the resolution of the first wireless device (i.e., no production test connection is established within the first time period), step T5 is executed.

[0071] In step T5, if the first wireless device does not establish a production test connection within the first time period, the current state of the first wireless device is updated to a waiting-for-pairing state.

[0072] In step T6, a second production test broadcast signal sent by the test device is monitored in the second time period, the second production test broadcast signal is used to guide the first wireless device to establish a production test connection with the test device, and the second production test broadcast signal has test feature information for the wireless device to identify. If the first wireless device monitors the second production test broadcast signal in the second time period, step T7 is executed; if the first wireless device does not monitor the second production test broadcast signal in the second time period, step T8 is executed.

[0073] In actual applications, the test device periodically performs the production test monitoring operation and the production test broadcast operation, that is, the test device can act as a guide for the production test connection to send a production test broadcast signal, or as a guided party for the production test connection to monitor the production test broadcast signal. In an embodiment of the present invention, if the first wireless device does not establish a production test connection within a first time period after being turned on, the test device, as a guide, continues to attempt to establish a production test connection with the first wireless device.

[0074] In the waiting-for-pairing state, the first wireless device will periodically perform the production test monitoring operation and the pairing connection operation respectively. If the production test connection is not established within the second time period, the pairing connection operation will be performed after the second time period ends; if the pairing connection is not established within the third time period, the production test monitoring operation will be performed after the third time period ends; the cycle will be repeated until the production test connection or the pairing connection is established, so that the first wireless device is updated from the current waiting-for-pairing state to other states. The second time period is the duration of the production test monitoring operation within a cycle, and the third time period is the duration of the pairing connection operation within a cycle.

[0075] In another implementation of the embodiment of the present invention, in the waiting pairing state, in addition to the above-mentioned production test monitoring operation and pairing connection operation, other operations (assuming to be the third operation) may be performed, and a duration will be configured for the third operation, and included in the entire execution cycle in the waiting pairing state, such as, according to the duration of each operation, the production test monitoring operation, the pairing connection operation and the third operation are performed in sequence, and when the third operation is completed, the production test monitoring operation will be returned to be performed, and the cycle will be repeated until the first wireless device is updated from the current waiting pairing state to other states. In addition, if there are other operations besides the third operation, the same is true, and they will not be repeated here.

[0076] In step T7, if the second production test broadcast signal is monitored, a second production test connection signal is sent to the test device that sends the second production test broadcast signal, so that the test device establishes a production test connection with the first wireless device, and the current state of the first wireless device is updated to the production test connection state, and step T12 is executed to perform a functional test. The second production test connection signal is a production test connection request signal sent by the first test device in response to the second production test broadcast signal.

[0077] In the embodiment of the present invention, after the second production test broadcast signal is monitored, the second production test broadcast signal is parsed to obtain the address information of the first wireless device, and a second production test connection signal is sent to the first wireless device based on the address information, the second production test connection signal including the agreed data transmission and reception time and the agreed data transmission and reception frequency band after the production test connection is established. In actual application, if the second production test broadcast signal is incorrect, resulting in a timeout of the first wireless device parsing (i.e., no production test connection is established within the second time period), the current production test monitoring operation of the first wireless device is stopped, and step T8 is executed.

[0078] In step T8, if the first wireless device does not establish a production test connection within the second time period, after the second time period ends, it sends a pairing connection broadcast signal within a third time period, where the pairing connection broadcast signal is used to find a second wireless device to establish a pairing connection with the first wireless device.

[0079] In step T9, a pairing connection response signal is monitored in the third time period, where the pairing connection response signal is a pairing connection request signal sent by the second wireless device in response to the pairing connection broadcast signal. If a pairing connection response signal is monitored in the third time period, step T10 is executed; if no pairing connection response signal is monitored in the third time period, step T6 is returned to execute.

[0080] In the embodiment of the present invention, the second wireless device is an electronic device that is paired with the first wireless device. For example, when the first wireless device is a microphone, the second wireless device may be a speaker.

[0081] In step T10, if the pairing connection response signal is monitored, the first wireless device establishes a pairing connection with the second wireless device, and updates the current state of the first wireless device to a paired state.

[0082] In step T11, in the paired state, the first wireless device intermittently monitors the second production test broadcast signal sent by the test device. If the second production test broadcast signal is monitored, the pairing connection with the second wireless device is disconnected, and the process returns to step T7. Specifically, the duration and interval of monitoring the second production test broadcast signal in the paired state can be determined according to actual needs and are not limited here.

[0083] In step T12, a functional test is performed on the first wireless device in the production test connection state.

[0084] In actual applications, the functional test may include a wireless transmission function (eg, a radio frequency function). Therefore, if the first wireless device does not establish a production test connection or a pairing connection within a preset test duration, it is confirmed that the wireless transmission function of the first wireless device is abnormal.

[0085] Exemplarily, it is assumed that the first wireless device is a microphone, the second wireless device is a speaker, and the test device is an electronic device with wireless transmission function and audio playback function, and the functional tests to be performed are the microphone pickup function test and the radio frequency function test. The tester turns on the microphone, waits for a period of time, and observes whether the connection indicator lights of the microphone and the test device are both valid (assuming that the green light indicates that the connection is valid). If the connection indicator lights of the microphone and the test device are both green, it means that the microphone and the test device have established a production test connection, and the radio frequency function of the microphone is normal. If only the microphone is green, it means that the microphone and the speaker have established a pairing connection, and the radio frequency function of the microphone is normal. At this time, the tester waits for a while until the connection indicator lights of the microphone and the test device are both green. After confirming that the microphone and the test device have established a production test connection, the tester speaks to the microphone, and the microphone can collect audio signals through the microphone, and transmit the audio signals to the test device through the physical frequency band agreed upon by the production test connection. If the test device can play the tester's speech audio normally, it is confirmed that the microphone's pickup function is normal. If the test device cannot play the tester's speech audio normally (including unclear audio playback or no audio playback at all), it is confirmed that the first wireless device's sound pickup function is abnormal. Further, if the first wireless device does not establish a production test connection or a pairing connection within the test time after being turned on, it is confirmed that the first wireless device's radio frequency function is abnormal.

[0086] In an embodiment of the present invention, the first wireless device enters a production test guidance state when it is turned on, and sends a first production test broadcast signal as a guide to guide the test device to establish a production test connection. If a production test connection is not established in the production test guidance state, the first wireless device enters a waiting-for-pairing state, and periodically monitors a second production test broadcast signal sent by the test device; if the first wireless device establishes a pairing connection with the second wireless device in the waiting-for-pairing state, the first wireless device enters a paired state, and intermittently monitors the second production test broadcast signal sent by the test device to establish a production test connection with the test device as a guided party. The embodiment of the present invention fully considers various possible states in an actual test environment to eliminate the influence of various situations, and to ensure as much as possible that the first wireless device can establish a production test connection with the test device when the wireless transmission function is normal, so as to ensure the accuracy of the functional test results.

[0087] In another embodiment of the present invention, both the production test guiding operation of sending the first production test broadcast signal and the production test monitoring operation of monitoring the second production test broadcast signal will become redundant operations after the product is qualified and shipped out of the factory. In order to avoid the impact of these redundant operations on users, the embodiment of the present invention proposes a function of closing the production test mode, specifically:

[0088] In the embodiment of the present invention, the physical buttons of the first wireless device have set functions, such as power on / off, volume up, volume down, mode switch key. The functions of these physical buttons have been defined when the product is designed, and the defined functions will be responded when the user presses the buttons.

[0089] When the first wireless device enters the production test connection state, the setting function of one of the physical buttons of the first wireless device can be changed to: the function of turning off the production test mode. When the function of turning off the production test mode is activated (for example, the tester operates the physical button), the following function of turning off the production test mode is executed: when the first wireless device is turned on, the first wireless device enters the production test guidance state and changes to the first wireless device entering the waiting pairing state; in the waiting pairing state and the paired state, the first wireless device no longer performs all production test monitoring operations. And after exiting the production test connection state, the setting function of the physical button is restored.

[0090] In an embodiment of the present invention, a function of shutting down the production test mode is proposed, so that the wireless device can shut down the production test mode after completing the production line test, thereby reducing redundant operations of the wireless device and improving the work efficiency of the user in performing ordinary pairing connection.

[0091] Figure 4 Another flow chart of the wireless device production line testing method according to an embodiment of the present invention is shown. Figure 4An embodiment of a wireless device production line testing method performed by a testing device in an embodiment of the present invention includes: steps H1 to H6.

[0092] In step H1, the test device monitors the first production test broadcast signal sent by the first wireless device. If the first production test broadcast signal is monitored within the fourth time period, step H2 is executed; if the first production test broadcast signal is not monitored within the fourth time period, step H4 is executed.

[0093] In step H2, if the first production test broadcast signal is monitored, the test device responds to the request of the first production test broadcast signal and sends a first production test connection signal to the first wireless device.

[0094] In step H3, the test device receives a response from the first wireless device to the first production test connection signal.

[0095] If the first wireless device responds to the request of the first production test connection signal, execute step H6 to perform a functional test. Exemplarily, if the BLE protocol is used as the communication scenario, after the test device sends the first production test connection signal to the first wireless device, the test device automatically switches to the production test connection state. After the first wireless device receives the first production test connection signal and successfully parses it, it will also switch to the production test connection state. There is no need to feed back a special response signal to the test device, and data is directly sent and received at the time point and frequency band agreed upon by the first production test connection signal. Therefore, if the test device receives the data sent by the first wireless device at the agreed time point and frequency band, it can be regarded as the first wireless device responding to the request of the first production test connection signal.

[0096] In other implementations of the communication protocol, it may also be agreed that if the first wireless device can establish a production test connection with the test device, the first wireless device needs to feed back a response signal of the first production test connection signal to the test device to confirm the establishment of the production test connection. In actual applications, the specific method for confirming the establishment of the production test connection can be determined according to actual needs and is not limited here.

[0097] In step H4, the test device sends a second production test broadcast signal to guide the first wireless device to establish a production test connection.

[0098] In step H5, the test device monitors the second test connection signal sent by the first wireless device.

[0099] If the second production test connection signal is monitored within the fifth time period, step H6 is executed to perform a functional test. If the second production test connection signal is not monitored within the fifth time period, the process returns to step H1.

[0100] Exemplarily, if the BLE protocol is used as the communication scenario, after the test device receives the second production test connection signal and successfully parses it, the test device automatically switches to the production test connection state to wait for the test data sent by the first wireless device through the production test connection.

[0101] In step H6, the testing device performs a functional test on the first wireless device through the production test connection.

[0102] Exemplarily, it is assumed that the first wireless device is a microphone, the test device is an electronic device with a wireless transmission function and an audio playback function, and the functional test to be performed is a microphone pickup function test. The tester turns on the microphone, waits for a period of time, and observes whether the connection indicator lights of the microphone and the test device are both valid (assuming that the green light indicates a valid connection). If the connection indicator lights of the microphone and the test device are both green, it means that the microphone and the test device have established a production test connection. If only the microphone is green, it means that the microphone has established a pairing connection with other devices. At this time, the tester waits for a while until the connection indicator lights of the microphone and the test device are both green. The tester speaks to the microphone, and the microphone can collect audio signals through the microphone and transmit the audio signals to the test device through the physical frequency band agreed upon by the production test connection. If the test device can play the tester's speech audio normally, it is confirmed that the microphone's pickup function is normal. If the test device cannot play the tester's speech audio normally (including unclear audio playback or no audio playback at all), it is confirmed that the pickup function of the first wireless device is abnormal.

[0103] The following takes the communication scenario of the BLE protocol as an example. Assuming that the first wireless device is a microphone, the second wireless device is a speaker, and the test device is an electronic device with wireless transmission and audio playback functions, the interaction process among the microphone, speaker, and test device is described. Figure 5 An interactive flow chart showing a method for testing a wireless device production line according to an embodiment of the present invention is shown in FIG. Figure 5 Another embodiment of the wireless device production line testing method in the embodiment of the present invention includes:

[0104] When the microphone is turned on, the microphone enters the production test guidance state as the advertiser in the BLE protocol. In the first time period T1, the microphone sends the first production test broadcast signal (ADV, Advertising) B1. For details, the data format of ADVB1 can be found in Figure 6 , Figure 6A format diagram of a broadcast signal in an embodiment of the present invention is shown. Among them, ADV ADDR represents the address information of the device sending the broadcast signal, ADV DATA represents the data of the broadcast signal, and ADV DATA includes multiple broadcast data units (AD Structure), and an AD Structure includes: length (Len), type (Type) and value (Value). Len represents the broadcast type and the data length of the broadcast data, occupying one byte (byte). Type represents the meaning of the broadcast data, occupying one byte. Value represents some data values ​​of the broadcast data. In an embodiment of the present invention, the test feature information carried in ADVB1 is the Value in the AD Structure. Exemplarily, when Value = "TEST1", it corresponds to the production test broadcast signal broadcasted by the microphone to the test device. When Value = "DEMO", it indicates that the broadcast signal is a paired connection broadcast signal. When Value = "TEST2", it corresponds to the production test broadcast signal broadcasted by the test device to the microphone.

[0105] When the test device receives ADV B1, it parses the message features of ADV B1 and finds "TEST1" in the Value of AD Structure. At this time, the test device successfully matches the microphone to be tested. Furthermore, as the initiator in the BLE protocol, the test device sends the first production test connection signal (CONNECT REQ1) to the microphone. CONNECTREQ1 carries parameters that determine the timing of subsequent communications, such as at which time point and which PhysicalChannel the two parties send and receive data. After sending CONNECT_REQ1, the test device automatically enters the production test connection state and becomes the master device (Master) in the BLE protocol. After receiving CONNECT_REQ1 and successfully parsing it, the microphone also automatically enters the production test connection state and becomes the slave device (Slave) in the BLE protocol.

[0106] When the speaker receives ADV B1, it parses the message features of ADV B1 and finds "TEST1" in the Value of AD Structure. At this time, the speaker does not do any processing.

[0107] If the microphone does not enter the production test connection state within the first time period T1, it will enter the waiting for pairing state and become the Initiator role in the BLE protocol. In the second time period T2, it monitors the second production test broadcast signal (ADV B3) sent by the test device. Among them, ADV B3 carries the test feature information of "TEST2", that is, the Value in ADV B3 = "TEST2", and TEST2 corresponds to the production test broadcast signal broadcast by the test device to the microphone. When the microphone monitors the test device ADV B3 and successfully parses it, it sends the second production test connection signal CONNECT_REQ3 to the test device. After sending CONNECT_REQ3, it automatically enters the production test connection state and becomes the Master role in the BLE protocol. After receiving CONNECT_REQ3 and successfully parsing it, the test device also automatically enters the production test connection state and becomes the Slave role in the BLE protocol.

[0108] When the speaker receives ADV B3, it parses the message features of ADV B3 and finds "TEST2" in the Value of AD Structure. At this time, the speaker does not do anything.

[0109] If the microphone does not enter the production test connection state within T2 of the waiting pairing state, it switches to the advertiser role in the BLE protocol and sends a pairing connection broadcast signal (ADV B2). When the test device receives ADV B2, it parses the message characteristics of ADV B2 and finds "DEMO" in the value of AD Structure. At this time, the test device does not do anything. When the speaker receives ADV B2, it parses the message characteristics of ADV B2 and finds "DEMO" in the value of AD Structure. At this time, the speaker, as the initiator role in the BLE protocol, sends a pairing connection response signal (CONNECTREQ2) to the microphone. CONNECT REQ2 carries the parameters that determine the timing of subsequent communication. After sending CONNECT_REQ2, the speaker automatically enters the paired state and becomes the Master role in the BLE protocol. After receiving CONNECT_REQ2 and successfully parsing it, the microphone also automatically enters the paired state and becomes the Slave role in the BLE protocol.

[0110] When the microphone enters the paired state, it intermittently monitors ADV B3 sent by the test equipment. If the microphone has not completed the functional test before pairing with the speaker. You can refer to the above-mentioned ADV B3 processing method to establish a production test connection with the test equipment. In actual applications, you can set the microphone to turn off the production test mode. When the microphone device enters the production test connection state, the setting function of one of the physical buttons of the microphone can be changed to: turn off the production test mode. When the function of turning off the production test mode is activated (for example, the tester operates the physical button), the following function of turning off the production test mode is executed: when the microphone is turned on, the microphone enters the production test guide state and changes to the microphone entering the pairing state; in the pairing state and the paired state, the microphone no longer performs all production test monitoring operations. And, after exiting the production test connection state, restore the setting function of the physical button.

[0111] Specifically, in the above interaction process, the conversion relationship between the microphone in various states can be referred to in Figure 7 , Figure 7 The diagram shows the conversion relationship of the microphone in various states in the embodiment of the present invention. When the microphone is turned on, the microphone immediately enters the production test guidance state and sends the broadcast signal of ADV B1. If a response from ADV B1 is received within T1, it switches to the production test connection state. If no response from ADV B1 is received within T1, it switches to the waiting for pairing state. In the waiting for pairing state, the production test monitoring operation (i.e., monitoring ADV B3) and the pairing connection operation (i.e., sending ADV B2 and waiting for the response from ADV B2) are periodically performed respectively. If a response from ADV B2 is received, it switches to the pairing connection state. If a response from ADV B3 is monitored, it switches to the production test connection state.

[0112] In an embodiment of the present invention, a tester is also provided, which includes a substrate and at least two unit interfaces arranged on the substrate, wherein the unit interfaces are used to connect test units; wherein each of the test units can be used as a test device to perform the wireless device production line test method in the above embodiment. Figure 8 , Figure 8 The schematic diagram of the structure of the tester in the embodiment of the present application is shown. The substrate of the tester can connect the audio outputs of N test units in parallel and output them through speakers or headphones, thereby improving the test efficiency.

[0113] In actual production line test scenarios, there are often multiple first wireless devices to be tested, and multiple test devices (wherein, if a tester has multiple independent test units, the tester can also be regarded as multiple test devices). In the embodiment of the present invention, the first-to-listen-first-respond and first-to-respond-first-connect processing method is adopted, so that each first wireless device and each test device will not interfere with each other, and the overall test efficiency can be improved.
