Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.
[0062] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.
[0063] Figure 1 This is a flowchart illustrating the data transmission method provided in an embodiment of the present invention, with reference to... Figure 1 The data transmission method provided in this embodiment of the invention includes the following steps:
[0064] Step 110: Associate the identification information of the peripheral device with the peripheral information and callback method of the peripheral device;
[0065] Step 120: Determine the target peripheral device from multiple peripheral devices based on the received identification information, and at least one of the peripheral information and callback method of the target peripheral device;
[0066] Step 130: Perform data transmission between the target peripheral device and the application based on at least one of the peripheral information of the target peripheral device and the callback method.
[0067] It should be noted that the data transmission method provided by this invention can be executed by a mobile electronic device, such as a mobile phone, tablet computer, laptop computer, PDA, in-vehicle electronic device, wearable device, ultra-mobile personal computer (UMPC), netbook, or personal digital assistant (PDA), etc., and this invention does not impose specific limitations. The following describes the technical solution of this invention in detail using a mobile phone executing the data transmission method provided in this embodiment as an example.
[0068] Optionally, in step 110, the identification information of the peripheral device is associated with the peripheral information of the peripheral device and the callback method.
[0069] When a mobile phone establishes a Bluetooth connection with a peripheral device, it records the device's identification information (denoted as key), peripheral information (denoted as peripheral), and callback methods, and associates and stores the identification information, peripheral information, and callback methods of each peripheral device.
[0070] The identification information refers to the unique identifier of the peripheral device, such as the address of the peripheral device, such as the Universal Unique Identifier (UUID) or the Media Access Control (MAC) address.
[0071] Optionally, when the mobile phone scans nearby peripheral devices as the central device, it saves the relevant information of the peripheral devices. iOS can use the UUID of the peripheral device as the unique identifier of the peripheral device (denoted as key), while Android can use the MAC address of the peripheral device as the key.
[0072] Peripheral information refers to the parameter information of peripheral devices, which may include, for example, the device name, the device signal strength, the device model, etc.
[0073] Callback methods are functions registered by the business layer to the connection layer for data communication. Callback methods can include status callback methods, data interaction callback methods, and disconnection callback methods. By associating the peripheral device's key with the callback method, the callback method can be saved using the key as a unique identifier.
[0074] In step 120, a target peripheral device is determined from multiple peripheral devices based on the received identification information, and at least one of the peripheral information and callback method of the target peripheral device is determined.
[0075] Based on step 110, the peripheral device's identification information, peripheral information, and callback method have been linked together. By determining the peripheral device's identification information from the data sent by the application (APP) or peripheral device, the target peripheral device, along with its peripheral information and callback method, can be identified from among multiple peripheral devices simultaneously connected to the mobile phone.
[0076] In step 130, data transmission between the target peripheral device and the application is performed based on at least one of the peripheral device information and callback method. Data sent by the application can be sent to the peripheral device via the target peripheral device's peripheral information; alternatively, data sent by the target peripheral device can be sent to the application via the target peripheral device's callback method. This achieves accurate data transmission between the target peripheral device and the application.
[0077] For example, Figure 2 This is one of the flowcharts illustrating the data transmission method provided in the embodiments of the present invention, see below. Figure 2 ,
[0078] When the phone enables Bluetooth scanning, it scans for devices A, B, and C, and records the device identification information (key), peripheral information, and callback method for each device.
[0079] When initiating a connection request to device A, the key1, peripheral1, and callback1 of device A are associated and stored; similarly, when initiating a connection request to device B, the key2, peripheral2, and callback2 of device B are associated and stored; and when initiating a connection request to device C, the key3, peripheral3, and callback3 of device C are associated and stored. As shown in Table 1:
[0080] Table 1. Related device information
[0081] Equipment A key1-peripheral1-callback1 Equipment B key2-peripheral2-callback2 Equipment C key3-peripheral3-callback3 … …
[0082] When a mobile phone is connected to multiple peripheral devices, by parsing the data sent by the peripheral devices and determining the key, it can be determined which device sent the data. Based on the key, the callback can be determined, and the data can be sent to the APP through the callback, thus realizing the data transmission between peripheral devices and the APP.
[0083] By parsing the data sent by the app and determining the key, it is possible to determine which device the data is to be sent to. Based on the key, the peripheral can be determined, and the data can be sent to the target peripheral device through the peripheral, thus realizing data transmission between the peripheral device and the app.
[0084] The data transmission method provided in this invention accurately identifies the target peripheral device among multiple peripheral devices by using the identification information of the peripheral device, along with the peripheral information and callback method of the target peripheral device. This enables accurate data transmission between the application and the target peripheral device, effectively solving the problem of data transmission accuracy in scenarios where multiple peripheral devices are connected, and providing users with a good intelligent experience.
[0085] In one embodiment, the data transmission method provided by this invention further includes:
[0086] Associate the identification information of peripheral devices with their encryption and decryption methods.
[0087] Optionally, once the mobile phone and peripheral device are successfully connected, they can negotiate a key to ensure the accuracy of the connection and data transmission. Therefore, when establishing a Bluetooth connection between the mobile phone and the peripheral device, different keys can be set for different peripheral devices and recorded to obtain the encryption and decryption methods of the peripheral devices.
[0088] By associating the encryption and decryption methods of peripheral devices with their identification information, the target peripheral device can be identified after obtaining the identification information, and the decryption and encryption methods of the target peripheral device can also be determined.
[0089] The data transmission method provided in this embodiment of the invention can ensure the security of data transmission in scenarios where multiple external devices are connected by associating the identification information of the peripheral device with the encryption and decryption methods of the peripheral device.
[0090] In one embodiment, determining a target peripheral device from a plurality of peripheral devices based on received identification information, and at least one of peripheral information of the target peripheral device and a callback method, includes:
[0091] Receive the first data sent by the target peripheral device;
[0092] The identification information of the target peripheral device is determined from the first data, and the decryption method and data interaction callback method of the target peripheral device are determined based on the identification information of the target peripheral device.
[0093] The decryption method of the target peripheral device is used to decrypt the data to be sent in the first data.
[0094] The data interaction callback method of the target peripheral device is used to send the decrypted data to be sent to the application.
[0095] Optionally, after the mobile phone establishes a Bluetooth connection with the peripheral device, data interaction can be performed.
[0096] When the target peripheral device sends data to the app, it first sends the data to the phone. After receiving the data sent by the target peripheral device, the phone parses the data to obtain the identification information of the target peripheral device. This allows it to identify the target peripheral device from among multiple connected peripheral devices, as well as the decryption method and data interaction callback method of the target peripheral device.
[0097] The received data is decrypted using the Bluetooth protocol and the target peripheral device's decryption method, and then sent to the app via a data interaction callback method. Once the app receives the data, it can perform subsequent business operations. The app can also inform the user of data sent by the target peripheral device via voice, text, or video.
[0098] The data transmission method provided in this embodiment of the invention determines the callback method and decryption method of the target peripheral device through the identification information of the peripheral device, and sends the data sent by the target peripheral device to the application according to the decryption method and the callback method, thereby realizing the accuracy and security of data transmission between the peripheral device and the application.
[0099] In one embodiment, determining a target peripheral device from a plurality of peripheral devices based on received identification information, and at least one of peripheral information of the target peripheral device and a callback method, includes:
[0100] Receive the second data sent by the application;
[0101] The identification information of the target peripheral device is determined from the second data, and the encryption method and peripheral information of the target peripheral device are determined based on the identification information of the target peripheral device.
[0102] The encryption method of the target peripheral device is used to encrypt the data to be sent in the second data.
[0103] The peripheral information of the target peripheral device is used to send the encrypted data to the target peripheral device.
[0104] Optionally, after the mobile phone and the peripheral device establish a Bluetooth connection, data interaction can begin. When the APP sends data to the peripheral device, it first sends the data to the mobile phone. After receiving the data sent by the APP, the mobile phone parses the data sent by the APP to obtain the identification information of the target peripheral device. It can then identify the target peripheral device from among the multiple connected peripheral devices, as well as the encryption method and peripheral information of the target peripheral device.
[0105] The data sent by the APP is assembled according to the Bluetooth protocol, then encrypted using encryption methods, and finally sent to the target peripheral device according to the peripheral device information.
[0106] The data transmission method provided in this invention determines the peripheral information and encryption method of the target peripheral device through the identification information of the peripheral device, and sends the data sent by the application to the target peripheral device according to the encryption method and the peripheral information, thereby achieving the accuracy and security of data transmission between the peripheral device and the application.
[0107] In one embodiment, determining a target peripheral device from a plurality of peripheral devices based on received identification information, and at least one of peripheral information of the target peripheral device and a callback method, includes:
[0108] Receive third data sent by the target peripheral device;
[0109] The identification information of the target peripheral device is determined from the third data, and the disconnection callback method of the target peripheral device is determined based on the identification information of the target peripheral device;
[0110] The disconnection callback method for the target peripheral device is used to upload the disconnection information of the target peripheral device to the application.
[0111] Optionally, when the mobile phone actively disconnects from the target peripheral device, the target peripheral device is identified based on the device's identification information, the disconnection method is executed, and a callback notification of successful disconnection is awaited.
[0112] When a callback indicating a successful passive disconnection is received from the target peripheral device, or a callback indicating that the target peripheral device has actively disconnected the Bluetooth connection, the disconnection callback method of the target peripheral device can be determined based on the device's identification information. By calling the disconnection callback method, the device disconnection information can be accurately reported to the APP.
[0113] At the same time, based on the identification information of the target peripheral device, the pre-stored peripheral information and callback methods of the target peripheral device are cleared.
[0114] The data transmission method provided in this embodiment of the invention disconnects from the target peripheral device using the identification information of the peripheral device, and after receiving the disconnection success information sent by the target peripheral device, calls the disconnection callback method to upload the disconnection information of the target peripheral device to the application, thus ensuring the accuracy of data transmission.
[0115] In one embodiment, determining a target peripheral device from a plurality of peripheral devices based on received identification information, and at least one of peripheral information of the target peripheral device and a callback method, includes:
[0116] Receive the fourth data sent by the target peripheral device;
[0117] The identification information of the target peripheral device is determined from the fourth data, and the status callback method of the target peripheral device is determined based on the identification information of the target peripheral device;
[0118] The target peripheral device's status callback method is used to upload the target peripheral device's status information to the application.
[0119] Optionally, during the connection process with the peripheral device, the system can monitor changes in the Bluetooth status and connection status of the target peripheral device and monitor the status information of the peripheral device in real time.
[0120] Based on the data sent by the peripheral device, find the status callback method of the peripheral device. By calling the callback method of the peripheral device, the current status of the peripheral device can be reported to the APP, so as to accurately know the current status of the device.
[0121] The data transmission method provided in this embodiment of the invention determines the status callback method of the peripheral device through the identification information of the peripheral device, and then calls the status callback method to accurately upload the status of the peripheral device to the application, thereby realizing precise monitoring of the status of the peripheral device.
[0122] In one embodiment, associating the identification information of the peripheral device with the peripheral information of the peripheral device and the callback method includes:
[0123] The peripheral device's identification information is used as the key, and the peripheral device's peripheral information and callback method are used as the value to form a key-value pair;
[0124] Store key-value pairs in a preset device pool.
[0125] Optionally, when initiating a Bluetooth connection to a peripheral device, a device pool is created, with the peripheral device's identification information as the key and the peripheral device's peripheral information and callback method as the value, forming key-value pairs, and the key-value pairs are stored in the device pool.
[0126] The data transmission method provided in this embodiment of the invention forms key-value pairs using identification information as the key and peripheral information and callback method of the peripheral device as the value, and stores them in the device pool. This allows the peripheral information and callback method of the target peripheral device to be determined directly in the device pool, ensuring the accuracy of data transmission.
[0127] In one embodiment, the identification information of the peripheral device is determined in the following way:
[0128] Identify peripheral devices via Bluetooth scanning;
[0129] It receives broadcast packet data sent by peripheral devices and parses the broadcast packet data to determine the identification information of the peripheral devices.
[0130] Optionally, power on the peripheral device and set it to Bluetooth broadcast mode, allowing it to be discovered by the mobile phone as the central Bluetooth administrator. Open the app, obtain Bluetooth permissions, and turn on the phone's Bluetooth; use the mobile phone as the Bluetooth central device, and set the peripheral's service UUID and rules for discovering the peripheral device.
[0131] When a mobile phone enables Bluetooth to scan for nearby peripheral devices, it receives broadcast packet data sent by the peripheral devices. By parsing the peripheral device broadcast packet data, the UUID or MAC of the peripheral device can be obtained, which is the identification information of the peripheral device.
[0132] The data transmission method provided in this embodiment of the invention determines the unique identifier of the peripheral device by parsing the broadcast data sent by the peripheral device, thus ensuring the accuracy of the peripheral device's identification information.
[0133] Figure 2 This is one of the flowcharts illustrating the data transmission method provided in the embodiments of the present invention. Figure 3 This is a second schematic flowchart illustrating the data transmission method provided in this embodiment of the invention, referred to... Figure 2 and Figure 3 The data transmission method provided in this embodiment of the invention includes the following steps:
[0134] Step 1: When the mobile phone scans nearby peripheral devices as the central device, it saves the relevant information of the peripheral devices. iOS can use the peripheral device's UUID as its unique identifier (denoted as the key, the same below), while Android can use the peripheral device's MAC address as the key. The specific steps are as follows:
[0135] 1. Power on the Bluetooth device and put it into Bluetooth broadcast mode so that the device can be discovered by a Bluetooth administrator using a mobile phone as the central hub;
[0136] 2. Open the app, obtain Bluetooth permission, and turn on your phone's Bluetooth; use your phone as the Bluetooth central device, and set the service UUID of the peripheral device and the rules for discovering the device;
[0137] 3. The phone enables Bluetooth to scan and discover nearby peripherals, receives broadcast packet data sent by nearby peripherals, parses the broadcast packet data, and obtains the UUID or MAC of the peripheral object;
[0138] 4. Determine the target device according to the rules for discovering peripherals, record the peripheral object (denoted as peripheral), and record the unique identifier key corresponding to the peripheral, then stop scanning.
[0139] Step 2: When connecting devices and communicating data, the status callbacks and data communication during the Bluetooth connection establishment process between the phone and the peripheral device need to find the corresponding peripheral device in the device pool through the key to ensure accurate data transmission. The specific steps are as follows:
[0140] 1. Based on the peripheral device obtained in step 1, the central device initiates a connection request to the peripheral device;
[0141] 2. Create a device pool, and store device information such as the peripheral and callback methods in the device pool using the key and peripheral of the peripheral device as key-value pairs;
[0142] 3. Monitor changes in Bluetooth status and connection status during the connection process, find the status callback method of the target peripheral device in the device pool based on the peripheral key, and call the callback method to report the status of the target peripheral device to the upper-layer business.
[0143] 4. After successful connection, key negotiation will be performed to ensure the security of Bluetooth connection and data exchange;
[0144] 5. Entering the data interaction stage, when the mobile phone receives data sent by the target peripheral device, it first determines the key in the peripheral. Based on the key in the device pool, it determines the data interaction callback method and decryption method in the device information. It decrypts the data according to the Bluetooth protocol and decryption method, and reports the decrypted data to the APP through the data interaction callback method.
[0145] 6. When the APP needs to send data to the device, it assembles the data according to the Bluetooth protocol and then encrypts the data using an encryption method; based on the key sent in, it finds the peripheral in the device pool, and the Bluetooth central administrator sends the encrypted data to the target peripheral device.
[0146] Step 3: When disconnecting the device, if the phone loses connection with the peripheral, the corresponding peripheral needs to be located in the device pool using the key. The connection to the corresponding peripheral should be canceled and the data cleared. The specific steps are as follows:
[0147] 1. When the phone actively disconnects from the peripheral device, the peripheral is located based on the key, the disconnect method is executed, and a callback notification of successful disconnection is awaited;
[0148] 2. When a callback for successful passive disconnection or a callback for active Bluetooth disconnection is received, the disconnection callback method in the device information in the device pool is obtained based on the peripheral key, and the device disconnection information is accurately reported to the APP.
[0149] 3. Clear the device information in the device pool using the key, and the device connection ends.
[0150] Based on the above steps, by storing device information such as the peripheral device's unique identifier key, status callback methods, data interaction callback methods, and disconnection callback methods, the system can accurately locate the corresponding device callback method when a relevant service is detected, and report the data to the upper-level business layer. The upper-level business layer can then accurately process the service, thereby ensuring the stability of the app's functionality.
