[0052] First, some terms in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

[0053] Low Power Wide Area Network LoRa (Long Range): is a low power wide area network (LPWAN) technology used for long-range wireless communication.

[0054] Pulse Width Modulation PWM (Pulse Width Modulation): is a technology that controls power transmission by adjusting the width of the pulse.

[0055] The above is a brief introduction to the nouns involved in the embodiments of the present application, which will not be repeated below.

[0056] Taking the wireless communication module as LoRa module as an example, the supplier of LoRa module needs to design different LoRa module models according to the different frequency bands in each country. If the integrator cannot identify the module information of the connected LoRa module on the product side, it is necessary to design different firmware for the LoRa module of each frequency band. This not only increases the complexity of product design, but also increases the cost of product maintenance.

[0057] This application example provides an example of a smart device, please refer to Figure 1 As shown, Figure 1 A schematic diagram of the structure of a smart device provided by the present application is shown, and the smart device includes:

[0058] A wireless communication module 101, wherein the wireless communication module comprises a plurality of pins;

[0059] The main control module 102 is integrated on the circuit board of the above-mentioned smart device, and is used to determine the module information of the above-mentioned wireless communication module based on the level signal or waveform code of at least one pin of the above-mentioned wireless communication module after the above-mentioned wireless communication module is plugged into the circuit board of the above-mentioned smart device.

[0060] Optionally, the module information includes at least one of the following information: type information and frequency band information.

[0061] Optionally, the smart device may also be referred to as an integrator device, such as any type of smart IoT device.

[0062] In the example of this application, multiple pins of a wireless communication module (such as a low-power wide area network LoRa module or other wireless communication module that requires frequency band identification) have different functions, and various information about the module is transmitted through the level signals or waveform codes output by these pins. For example, some pins may be used to transmit connection status information, while some pins are specifically used to transmit module information such as the type or frequency band of the module.

[0063] It should be understood that the specific definitions and functions of the pins of different types of wireless communication modules may vary, but overall they are designed around the goal of achieving effective communication with the main control module and accurately conveying their own characteristics.

[0064] In the example of the present application, the main control module in the smart device is integrated on the circuit board of the smart device. By reading the level status of the interrupt pin of the wireless communication module, a simple judgment of the module connection status is achieved. After the main control module determines that the wireless communication module is successfully plugged into the circuit board, the module information (type information and / or frequency band information) of the wireless communication module is determined based on the level signal or waveform coding of at least one pin of the above-mentioned wireless communication module, so that the smart device can communicate with the wireless communication module based on the module information.

[0065] More importantly, based on the acquired level signal or waveform encoding, the main control module determines the module information of the wireless communication module according to the pre-set rules and logic, so that the smart device can correctly communicate with the wireless communication module. In the example of this application, the module information includes at least one or more of type information and frequency band information.

[0066] For example, the type information can be used to determine the specific model of the wireless communication module through the level combination of specific pins (such as different combinations of several encoding pins outputting high or low levels respectively). For example, if the combination of encoding pin A being high and encoding pin B being low corresponds to a certain model of wireless communication module, then when the main control module detects this level combination, the specific model of the wireless communication module can be clearly determined.

[0067] For example, the frequency band information can be obtained by parsing an encodable waveform (such as a PWM signal) output by a certain pin. For example, according to a predetermined data protocol, the frequency and duty cycle of the signal output by a certain PWM pin are parsed. Different frequency and duty cycle combinations correspond to different frequency bands, thereby determining the frequency band information of the wireless communication module.

[0068] The design architecture of the smart device provided in the example of this application enables the smart device to automatically identify the module information of the connected wireless communication module without excessive human intervention. This can not only improve the intelligence level of the smart device, but also reduce the complexity of the smart device configuration and enhance the compatibility of the smart device, thereby reducing the need for different firmware.

[0069] For example, in the wide range of application scenarios of smart IoT devices, different application scenarios require the use of wireless communication modules of different types and frequency bands. Through this smart device that can automatically identify the characteristics of the wireless communication module, it is easier to deploy, upgrade and maintain the device, ensuring that the device can achieve good communication and collaborative work with the wireless communication module in different environments.

[0070] In one possible implementation, Figure 2 or Figure 3 As shown (taking the LoRa module as an example), the multiple pins include an IRQ interrupt pin; the interrupt pin is used to output a high-level signal when the wireless communication module establishes a connection with the smart device, and output a low-level signal when the wireless communication module is disconnected from the above-mentioned smart device; the main control module is used to determine that the wireless communication module is connected to the smart device when a high-level signal output by the interrupt pin is detected, and to determine that the wireless communication module is disconnected from the smart device when a low-level signal output by the interrupt pin is detected.

[0071] In the example of this application, when the wireless communication module starts to establish a connection with the smart device, if the connection is successfully established, the interrupt pin will output a high-level signal. For example, in an actual hardware connection scenario, when the wireless communication module is inserted into the corresponding slot of the smart device or the relevant electrical connection is completed, the level state of the interrupt pin will change immediately from the initial state (which may be a low level or an uncertain state) to a high level. This high-level signal is a clear indication that the main control module has successfully established a connection relationship with the smart device.

[0072] On the contrary, when the connection between the wireless communication module and the smart device is disconnected due to some reason (such as the wireless communication module is manually unplugged, the connection line fails, etc.), the interrupt pin will output a low-level signal accordingly. For example, if the user unplugs the wireless communication module during the operation of the device, the level of the interrupt pin will change from the high-level state when it was previously connected to the low-level state, thereby conveying to the main control module that the connection between the wireless communication module and the smart device has been disconnected.

[0073] The main control module has been monitoring the level status of the interrupt pin. When it detects a high-level signal output by the interrupt pin, it clearly determines that the wireless communication module has successfully established a connection with the smart device according to the pre-set logic and functions. At this time, the main control module carries out a series of subsequent operations based on this judgment, such as starting the communication initialization process with the wireless communication module, configuring related communication parameters, etc., so as to be able to carry out normal information exchange and communication collaboration with the wireless communication module that has just been connected.

[0074] Similarly, when the main control module detects a low-level signal output by the interrupt pin, it can quickly determine that the connection between the wireless communication module and the smart device has been disconnected. In this case, the main control module can take corresponding measures, such as suspending communication operations related to the wireless communication module, releasing resources previously occupied for communication with the module (such as cache space, communication ports, etc.), and can also record relevant information about the disconnection for subsequent troubleshooting or status statistics.

[0075] By outputting different level signals through the interrupt pin when the connection is established and disconnected, and the accurate detection and corresponding processing of these level signals by the main control module, the smart device can realize real-time monitoring and effective management of the connection status of the wireless communication module, thereby ensuring the stable operation and normal communication of the smart device.

[0076] In a possible implementation, if the plurality of pins include at least two encoding pins, then:

[0077] The at least two encoding pins are used to respectively output a high level signal and / or a low level signal after the wireless communication module establishes a connection with the smart device;

[0078] The main control module is further used to obtain the type information of the wireless communication module according to the high level signal and / or low level signal respectively output by the at least two encoding pins.

[0079] In the above implementation, different wireless communication module models may correspond to different encoding pin level combinations.

[0080] For example, the main control module is integrated on the circuit board of the smart device and maintains a connection with the encoding pin of the wireless communication module. If the wireless communication module establishes a connection with the smart device, the main control module monitors and reads the high-level signal and / or low-level signal output by each encoding pin in real time.

[0081] In an alternative example, Figure 2As shown, if at least two encoding pins are: the first encoding pin GPIO1 and the second encoding pin GPIO0, when the wireless communication module is connected to the smart device, if it is detected that the first encoding pin GPIO1 outputs a low level, and the second encoding pin GPIO0 outputs a low level, it indicates that the type information of the wireless communication module is model A; if it is detected that the first encoding pin GPIO1 outputs a low level, and the second encoding pin GPIO0 outputs a high level, it indicates that the type information of the wireless communication module is model B; if it is detected that the first encoding pin GPIO1 outputs a high level, and the second encoding pin GPIO0 outputs a low level, it indicates that the type information of the wireless communication module is model C. If it is detected that the first encoding pin GPIO1 outputs a high level, and the second encoding pin GPIO0 outputs a high level, it indicates that the type information of the wireless communication module is model D, and so on.

[0082] In addition, if Figure 2 or Figure 3 As shown, the OTHER pin represents other pins of the wireless communication module, which are used to realize the function in specific communication.

[0083] For example, a corresponding table is pre-stored inside the main control module, and the corresponding table records in detail the mapping relationship between different coding pin level combinations and wireless communication module types. When the main control module reads the current level combination of the above two coding pins, such as the level signal combination in which the output level signal of GPIO0 is high and the output level signal of GPIO1 is low, the main control module searches and matches in the pre-stored corresponding table based on the level signal combination. Assuming that in the corresponding table, the combination of "GPIO0 is high and GPIO1 is low" corresponds to a wireless communication module of a specific model (such as model B), the main control module can determine that the type information of the currently connected wireless communication module is model X.

[0084] In this way, by utilizing the combination of different level signals output by at least two encoding pins, the main control module can accurately and efficiently obtain the type information of the wireless communication module, thereby providing the necessary basic information for subsequent operations such as adaptation communication, functional configuration, etc. between the smart device and the wireless communication module.

[0085] In a possible implementation, if the multiple pins include a pulse width modulation signal PWM pin (such as Figure 3 WAVE pin shown), then:

[0086] The above-mentioned PWM pin is used to output a PWM signal after the above-mentioned wireless communication module establishes a connection with the above-mentioned smart device, and adopts a predetermined data protocol to obtain a waveform code based on the frequency and duty cycle of the above-mentioned PWM signal, and outputs the above-mentioned waveform code to the above-mentioned main control module.

[0087] The main control module is also used to parse the waveform code using the predetermined data protocol to obtain the frequency and duty cycle of the PWM signal, and determine the type information and frequency band information of the wireless communication module according to the frequency and duty cycle of the PWM signal.

[0088] In the example of the present application, after the wireless communication module establishes a connection with the smart device, the PWM pin in the wireless communication module outputs a PWM signal, which has specific frequency and duty cycle characteristics. Subsequently, according to a predetermined data protocol, a waveform code is generated based on the frequency and duty cycle of the PWM signal. For example, the predetermined data protocol may, but is not limited to, stipulate that: a PWM signal in a certain frequency range corresponds to the beginning of the transmission of information about the type of the wireless communication module, and within this frequency range, different duty cycles correspond to different specific types; for the transmission of frequency band information, it is another PWM signal in a specific frequency range, and different duty cycles within it also correspond to different frequency bands.

[0089] The following is a specific illustration using a simple example. If the predetermined data protocol is set: a PWM signal with a frequency of 50 Hz is used to transmit type information. At this frequency, a duty cycle of 30% corresponds to a wireless communication module of model A, and a duty cycle of 50% corresponds to a wireless communication module of model B; and a PWM signal with a frequency of 80 Hz is used to transmit frequency band information. At this frequency, a duty cycle of 20% corresponds to frequency band 1, and a duty cycle of 40% corresponds to frequency band 2.

[0090] Furthermore, the waveform code generated by the wireless communication module is output from the PWM pin and transmitted to the main control module to ensure that the main control module can receive the waveform code for parsing the relevant information of the wireless communication module. After the main control module receives the waveform code from the PWM pin, it first uses a pre-set predetermined data protocol to parse it to accurately obtain the frequency and duty cycle information of the PWM signal.

[0091] Continuing with the above example, if the waveform code received by the main control module is parsed to obtain a PWM signal feature with a frequency of 50 Hz and a duty cycle of 50%, it can be clearly determined that this part of information is related to the type of wireless communication module.

[0092] According to the frequency and duty cycle of the PWM signal obtained by analysis, the main control module further determines the type information and frequency band information of the wireless communication module. Still as in the specific example given above, when the main control module analyzes the frequency as 50Hz and the duty cycle as 50%, according to the predetermined data protocol, the main control module can determine that the type of the current wireless communication module is model B; if the main control module then analyzes the PWM signal characteristics of the frequency as 80Hz and the duty cycle as 40%, it can be determined that the corresponding frequency band is frequency band 2.

[0093] Through the above implementation method, by utilizing the PWM signal output by the PWM pin and the waveform coding generation and parsing process based on the predetermined data protocol, the main control module can accurately obtain the type information and frequency band information of the wireless communication module, thereby providing a key basis for subsequent adaptation, communication settings and other operations between the smart device and the wireless communication module.

[0094] In a possible implementation, the data frame structure of the predetermined data protocol includes:

[0095] A synchronization header, including the frequency and duty cycle of the PWM signal, used to mark the beginning of the data frame;

[0096] The type field is used to indicate the type information obtained by encoding the above frequency;

[0097] A data field is used to represent a data value obtained by encoding the above duty cycle;

[0098] Checksum field, used for error detection.

[0099] Specifically, in the example of this application, the synchronization header contains the frequency and duty cycle information of the PWM signal, which plays a vital role in the entire data frame structure and is used to clearly identify the beginning of a data frame. For example, it is stipulated that when the frequency of the PWM signal is a specific value (such as 50Hz) and the duty cycle is a fixed ratio (such as 20%), it means that a new data frame is about to start transmitting relevant information.

[0100] For the main control module, by detecting whether the frequency and duty cycle of the PWM signal meet the set value of the synchronization header, the starting position of the data frame can be accurately determined. If the synchronization header cannot be accurately identified, data parsing errors may occur, and relevant information of the wireless communication module cannot be correctly obtained.

[0101] Furthermore, the type field is mainly used to indicate the type information obtained after encoding the frequency of the PWM signal. Specifically, according to the rules set in the predetermined data protocol, different frequency values ​​correspond to different wireless communication module types through specific encoding methods. For example, a PWM signal with a frequency of 50Hz is encoded and represented as a wireless communication module of model A in the type field, while a PWM signal with a frequency of 80Hz is encoded and represented as a wireless communication module of model B in the type field. When parsing the data frame, the main control module can quickly determine the type information of the current wireless communication module by reading the content of the type field and based on the pre-known encoding rules.

[0102] The data field is used to represent the data value obtained after encoding the duty cycle of the PWM signal. Also according to the provisions of the predetermined data protocol, different duty cycles will be encoded into different data values, and these data values ​​correspond to different information contents. For example, a PWM signal with a duty cycle of 30% may be represented as a value within a certain frequency band (such as frequency band 1) in the data field after being encoded, and a PWM signal with a duty cycle of 50% may be represented as a value within another frequency band (such as frequency band 2) in the data field after being encoded.

[0103] By parsing the content of the data field and following the coding rules, the main control module can obtain specific data value information such as the frequency band, which helps the smart device to accurately understand the relevant characteristics of the wireless communication module. For example, it can set appropriate communication parameters according to the obtained frequency band information to ensure smooth communication with the wireless communication module.

[0104] The check field is used for error detection. During data transmission, various interference factors may cause data errors. The check field verifies the entire data frame (including the synchronization header, type field, and data field) by using a specific check algorithm (such as CRC check).

[0105] For example, when the transmitting end (wireless communication module) generates a data frame according to a predetermined data protocol, a check value is calculated based on the data content and filled into the check field. When the data frame is transmitted to the main control module, the main control module also calculates the received data frame according to the check algorithm and compares the calculation result with the value in the check field: if the two are consistent, it means that the data transmission is correct; if they are inconsistent, it means that an error occurred during the data transmission process, and the main control module may take corresponding measures, such as requesting the data frame to be resent.

[0106] The following provides a specific value of the data frame structure of an optional predetermined data protocol to facilitate the implementation of the specific solution provided by this application:

[0107] Synchronous header:

[0108] Fixed frequency: 1kHz

[0109] Fixed duty cycle: 50%

[0110] Type field:

[0111] Module A: Frequency 2kHz

[0112] Module B: Frequency 3kHz

[0113] Module C: Frequency 4kHz

[0114] Data field (taking 8-bit data as an example):

[0115] Values ​​from 0-255 are mapped to duty cycles from 5%-100% (in 0.38% steps)

[0116] For example, when the data value is 123, the calculated duty cycle is:

[0117] Duty cycle = 5% + (123 × 0.38%) = 46.74% ≈ 48.4%

[0118] Check field: Simple parity check, with a specific duty cycle (such as 10% for odd check and 90% for even check).

[0119] In an optional example, assuming that the data value of the wireless communication module A needs to be transmitted, the waveform encoding of the predetermined data protocol is as follows: Figure 4 The data frame structure based on the above-mentioned predetermined data protocol, including the synchronization header, type field, data field and check field, can effectively realize the accurate transmission, encoding and parsing of information between the wireless communication module and the main control module, thereby ensuring that the smart device can accurately obtain key content such as the type information and frequency band information of the wireless communication module, and provide guarantee for good communication and collaborative work between the wireless communication module and the main control module (or smart device).

[0120] This application example provides an example of a method for identifying a wireless communication module. Please refer to Figure 5 As shown, Figure 5 A schematic flow chart of identifying a wireless communication module provided by the present application is shown. As an example but not a limitation, the method can be applied to or run in a smart device. The method includes:

[0121] S101, after the wireless communication module is plugged into the circuit board of the smart device, a level signal or waveform code of at least one pin of the wireless communication module is obtained.

[0122] S102, determining module information of the wireless communication module based on a level signal or waveform code of at least one pin of the wireless communication module, wherein the module information includes at least one of the following information: type information and frequency band information.

[0123] After the wireless communication module is plugged into the circuit board of the smart device (physical connection), the level signal or waveform code output by the pin of the wireless communication module can accurately reflect the characteristics and status of the module itself. Therefore, in the example of the present application, after the wireless communication module is plugged into the circuit board of the above-mentioned smart device, the main control module of the smart device is used to obtain the level signal or waveform code of at least one pin of the above-mentioned wireless communication module.

[0124] For example, some encoding pins of the wireless communication module can represent the type information of the wireless communication module through a specific level combination (such as two encoding pins outputting different combinations of high and low levels, respectively).

[0125] For another example, the PWM (pulse width modulation) pin of the wireless communication module can output an encodable PWM (pulse width modulation) signal. By capturing and analyzing the characteristics of these PWM signals such as frequency and duty cycle, more detailed information can be obtained. For example, according to a predetermined data protocol, different frequency and duty cycle combinations can encode the frequency band information of the wireless communication module and other related information.

[0126] In addition, the interrupt pin of the wireless communication module outputs a high level when the wireless communication module establishes a connection with the smart device, and outputs a low level when the connection is disconnected. By obtaining the level signal of the interrupt pin, the connection status between the wireless communication module and the smart device can be known, which is also part of the overall module information.

[0127] Based on the acquired level signal or waveform code of at least one pin of the wireless communication module, the module information is determined according to pre-set rules and logic. Specifically, the rules and logic can usually be formulated according to the specific design of the wireless communication module and the communication protocol between the smart device and the module.

[0128] There may be multiple ways to determine the type information. As mentioned above, it is determined by the level combination of the encoding pins. Assuming that there are two encoding pins GPIO1 and GPIO2, if the combination of GPIO1 being high and GPIO2 being low corresponds to a certain type of wireless communication module, then when this level combination is obtained, it can be determined that the type of the wireless communication module is the corresponding specific model.

[0129] The frequency band information can be determined by analyzing the pins (such as PWM pins) that output waveform encoding. For example, according to a predetermined data protocol, a signal output by a PWM pin, whose frequency is 50Hz and whose duty cycle is 30%, corresponds to a certain frequency band range. When a signal with corresponding frequency and duty cycle characteristics output by the PWM pin is captured, the frequency band information of the wireless communication module can be determined to be the corresponding frequency band range.

[0130] Through the above-mentioned wireless communication module identification method, the smart device can automatically and accurately identify the module information of the connected wireless communication module, including type information and frequency band information. This provides a strong guarantee for the flexible configuration, efficient communication and subsequent maintenance and upgrade of smart devices in different application scenarios. For example, in the application scenario of IoT devices, different IoT devices may need to be equipped with wireless communication modules of different types and frequency bands. Through this identification method, the device can quickly adapt to different modules, reduce manual intervention, and improve the intelligence and operation efficiency of the device.

[0131] In one possible implementation, if the multiple pins include at least two encoding pins, please refer to Figure 6 As shown, Figure 6 A schematic flow chart of identification of a wireless communication module provided by the present application is shown, specifically:

[0132] S101, obtaining a level signal of at least one pin of the wireless communication module, including: S201, obtaining a high level signal and / or a low level signal respectively output by the at least two encoding pins;

[0133] S102, determining the module information of the wireless communication module based on the level signal of at least one pin of the wireless communication module, including: S202, combining the high level signal and / or low level signal respectively output by the at least two encoding pins to obtain the type information of the wireless communication module.

[0134] After the wireless communication module is plugged into the circuit board of the smart device, the operation of obtaining the encoding pin level signal is performed. This is because only when the wireless communication module is physically connected to the smart device and is in an operable state, the encoding pin will output the corresponding level signal according to its designed function.

[0135] In the example of this application, each encoding pin may output a high level or a low level, and different encoding pin combinations output different levels. These different level combinations are used to convey the type information of the wireless communication module. For example, assuming there are two encoding pins, encoding pins GPIO1 and GPIO2, after the module is connected to the device, GPIO1 outputs a high level and GPIO2 outputs a low level; or GPIO1 outputs a low level and GPIO2 outputs a high level; or both output a high level or a low level, etc. There are many possible level combinations.

[0136] Based on the high level signal and / or low level signal respectively output by at least two encoding pins, the type information of the wireless communication module is obtained by combining the pre-set corresponding rules. For example, in the design process of the smart device or wireless communication module, the corresponding relationship between the encoding pin level combination and the module type is determined in advance. For example:

[0137] When GPIO1 is high and GPIO2 is low, the corresponding wireless communication module is model A. If GPIO1 is low and GPIO2 is high, the corresponding wireless communication module is model B. When both GPIO1 and GPIO2 are high, the corresponding wireless communication module is model C. By analogy, through this clear corresponding rule, when the main control module obtains the specific encoding pin level combination, it can accurately determine the type information of the wireless communication module.

[0138] In the example of this application, the implementation method of determining the type information of the wireless communication module by obtaining the level signal of at least two encoding pins has the following advantages: First, the simple level signal (high level or low level) output by the encoding pin is used to convey information, without the need for complex encoding and decoding processes, which is relatively simple and intuitive, easy to understand and implement. Secondly, it only needs to set accurate corresponding rules in advance. After obtaining the level signal of the encoding pin, the main control module can quickly and accurately determine the type information of the wireless communication module, thereby providing timely and accurate basis for subsequent adaptation, communication and other operations between the smart device and the wireless communication module.

[0139] In summary, in the process of identifying the wireless communication module, the type information of the wireless communication module can be determined in a simple and efficient manner, which supports the collaborative work of the entire smart device and the wireless communication module.

[0140] In one possible implementation, if multiple pins include a pulse width modulation signal PWM pin, please refer to Figure 7 As shown, Figure 7 A schematic flow chart of an optional wireless communication module identification provided by the present application is shown, specifically:

[0141] S101, obtaining a waveform code of at least one pin of the wireless communication module, including: S301, obtaining a waveform code based on a frequency and a duty cycle of a PWM signal using a predetermined data protocol;

[0142] S102, based on the waveform coding of at least one pin of the above-mentioned wireless communication module, determine the module information of the above-mentioned wireless communication module, including: S302, use the above-mentioned predetermined data protocol to parse the above-mentioned waveform coding to obtain the frequency and duty cycle of the above-mentioned PWM signal, and determine the type information and frequency band information of the above-mentioned wireless communication module according to the frequency and duty cycle of the above-mentioned PWM signal.

[0143] In the example of the present application, when a PWM pin is included among the multiple pins and after the wireless communication module is plugged into the circuit board of the smart device, a predetermined data protocol can be used to obtain waveform encoding based on the frequency and duty cycle of the PWM signal.

[0144] Specifically, the predetermined data protocol is a set of rules set in advance to regulate how to generate specific waveform codes based on the characteristics of the PWM signal (frequency and duty cycle). For example, the protocol may, but is not limited to, stipulate that: when the frequency of the PWM signal is in a certain range (such as 50Hz-100Hz), it corresponds to the part that transmits information about the type of wireless communication module; within this frequency range, different duty cycles (such as 30%, 50%, etc.) correspond to different specific types. When the frequency of the PWM signal is in another specific range (such as 150Hz-200Hz), it corresponds to the part that transmits frequency band information, and different duty cycles within this range correspond to different frequency bands.

[0145] Based on the above protocol, by detecting the actual frequency and duty cycle of the PWM signal output by the PWM pin, the encoding operation is performed according to the predetermined rules to obtain the waveform code. In an example, assuming that the frequency of the PWM signal is 60Hz (within the frequency range of the transmission type information) and the duty cycle is 40%, according to the predetermined data protocol, after a specific encoding calculation (which may involve mathematical operations, logical judgments, etc.), a specific waveform code corresponding to it will be generated.

[0146] After the main control module of the smart device obtains the waveform code, first, the waveform code is parsed using a predetermined data protocol. Since the waveform code is generated according to a predetermined data protocol, the parsing process is also performed in reverse according to the protocol. The original frequency and duty cycle information of the PWM signal can be accurately obtained through parsing. Continuing with the above example, if the obtained waveform code is parsed and the result is that the frequency of the PWM signal is 60Hz and the duty cycle is 40%, then the basic characteristics of the PWM signal are restored.

[0147] According to the frequency and duty cycle of the PWM signal obtained by analysis, the type information and frequency band information of the wireless communication module are further determined. The specific type is determined based on the correspondence between the type information and the frequency and duty cycle of the PWM signal in the predetermined data protocol. For example, if the protocol stipulates that a PWM signal with a frequency of 60Hz and a duty cycle of 40% corresponds to a wireless communication module of model A, then when such a feature is analyzed, it can be determined that the type of the current wireless communication module is model A.

[0148] Similarly, according to the corresponding relationship between the frequency band information and the PWM signal frequency and duty cycle in the protocol, it is determined that the frequency band of the wireless communication module is frequency band 1 when the PWM signal characteristics that meet the conditions are analyzed.

[0149] The above implementation method can obtain various module information such as type information and frequency band information of the wireless communication module by utilizing the PWM signal output by the PWM pin and generating and parsing the waveform code according to the predetermined data protocol, which is richer and more comprehensive than the information obtained only through simple level signals. In addition, the predetermined data protocol can be flexibly set according to actual needs. For example, the corresponding relationship between the frequency and duty cycle and the specific information in the protocol can be adjusted according to different wireless communication module models, frequency band ranges, etc., so as to adapt to changes in various application scenarios.

[0150] In addition, as long as the waveform coding is generated, parsed and the information is determined strictly in accordance with the predetermined data protocol, the type information and frequency band information of the wireless communication module can be obtained more accurately, providing a reliable basis for the effective communication and collaborative work between smart devices and wireless communication modules.

[0151] In summary, the above-mentioned implementation method including PWM pins and based on a predetermined data protocol plays an important role in acquiring and determining the module information of the wireless communication module, and can meet the needs of smart devices for accurately understanding the characteristics of the wireless communication module.
