The operating system of the mobile terminal may be an Android or IOS operating system.

In the method for processing bluetooth data of a mobile terminal provided in this embodiment, a data processing module waits to receive bluetooth data from an operating system in a data receiving thread, and if the bluetooth data from a bluetooth device of the operating system is received, executes an operation shown in step 101 in fig. 2-1; waiting for application data from the application module to be received in the data sending thread, and executing the operation shown in the figure 2-2; the operations shown in fig. 2-3 are performed in a data processing thread.

Step 101: the data processing module adds the Bluetooth data from the Bluetooth device to a receiving buffer area by using a serial queue, and sets a data adding flag bit.

In this embodiment, specifically, if the data processing module receives bluetooth data from the bluetooth device of the operating system through its own first callback function in the data receiving thread, step 101 is executed;

for example: the first callback function is: void callBack (unidentified char data, unidentified intdataLen); the parameter data comprises Bluetooth data from Bluetooth equipment of an operating system;

before the data processing module receives the bluetooth data from the bluetooth device of the operating system through its own first callback function, the method further includes: the data processing module registers a first callback function with the operating system, and accordingly: and after the operating system receives the Bluetooth data from the Bluetooth equipment, the operating system sends the received Bluetooth data from the Bluetooth equipment to the data processing module through the first callback function.

More specifically, before the data processing module receives the bluetooth data from the bluetooth device through the first callback function of the data processing module, the data processing module registers the first callback function in a system receiving function of the operating system; and after the system receiving function of the operating system receives the Bluetooth data from the Bluetooth equipment, the operating system sends the received Bluetooth data from the Bluetooth equipment to the data processing module through the first callback function.

if the operating system is an IOS system, the system receiving function may specifically be: -

(void)peripheral:(CBPeripheral*)peripheraldidUpdateValueForCharacteristic:(CBCharacteristic*)characteristic error:(nullable NSError*)error；

For example: the first receiving interface is: unknown int sendOrder

The second receiving interface is unscented int sendAsk

Step 202: the data processing module judges whether the downlink instruction mutual exclusion lock is locked, if so, the step 202 is returned to; otherwise, locking the downlink instruction mutual exclusion lock, and executing step 203;

step 203: the data processing module obtains a downlink instruction according to the downlink instruction sending request;

specifically, the data processing module obtains the downlink instruction effective data from the downlink instruction sending request, and organizes the downlink instruction including the downlink instruction effective data according to a preset protocol.

More specifically, the data processing module obtains downlink instruction effective data from a downlink instruction sending request, sets a sixth preset value on a first byte in the downlink instruction according to a preset protocol, sets a fourth preset value on a second byte of the downlink instruction, sets data on a third byte and a fourth byte of the downlink instruction according to the length of the downlink instruction effective data, sets the downlink instruction effective data behind the fourth byte, calculates data between the second byte and the downlink instruction effective data in the downlink instruction according to a preset algorithm to obtain a downlink instruction check value, and sets the downlink instruction check value behind the downlink instruction effective data to obtain the downlink instruction comprising the downlink instruction effective data.

For example: the data processing module obtains downlink instruction valid data 0102 from a downlink instruction sending request, sets a sixth preset value A5 on a first byte in a downlink instruction according to a preset protocol, sets a fourth preset value 02 on a second byte of the downlink instruction, sets data on a third byte and a fourth byte of the downlink instruction according to a length 2 byte of the downlink instruction valid data, sets the downlink instruction valid data behind the fourth byte, calculates a downlink instruction check value 03 from the second byte to the data "0200020102" between the downlink instruction valid data in the downlink instruction according to a preset algorithm, and sets the downlink instruction check value behind the downlink instruction valid data to obtain a downlink instruction "A5020002010203" including the downlink instruction valid data.

Step 204: the data processing module judges whether there is data in the uplink response buffer, if yes, step 205 is executed; otherwise, sending a downlink instruction to the bluetooth device through the operating system, and executing step 206;

in this embodiment, the downlink instruction is sent to the bluetooth device through the operating system, which specifically includes: and sending a downlink instruction to the Bluetooth device through the operating system by using the serial queue.

Step 205: the data processing module empties the data in the uplink response buffer, sends a downlink instruction to the bluetooth device through the operating system, and executes step 206;

specifically, the data processing module empties data in the uplink response buffer, and calls a system sending function of the operating system to send a downlink instruction to the bluetooth device.

For example: the data processing module empties the data in the uplink response buffer, calls a first system sending function public laptop setValue (byte [ ] value) of the Android operating system to put a downlink instruction into the feature, and calls a second system sending function public laptop magnetic characteristic (Bluetooth gateway characterised by the characteristic) to send the downlink instruction in the feature to the Bluetooth device.

Another example is: the data processing module empties the data in the uplink response buffer and calls a system sending function (void) write value (NSData) data for charateristic (CBcharateristic) type of the IOS system; and sending a downlink instruction to the Bluetooth equipment.

Step 206: the data processing module judges whether the time is overtime according to the overtime time, if not, the step 207 is executed: if yes, returning a timeout error to the application module, and returning to the step 201;

before the step 206 is executed for the first time, the method further includes: the data processing module obtains response overtime time from the downlink instruction sending request, and sets the overtime time of the data processing module according to the response overtime time.

Step 207: the data processing module judges whether data exists in the uplink delay application buffer area, if so, step 210 is executed; otherwise, go to step 208;

In this embodiment, if in step 304, the data processing module puts the uplink response valid data in the uplink response into the uplink response buffer, step 209 specifically includes: the data processing module takes the data in the uplink response buffer area as an uplink response result, returns the uplink response result to the application module, unlocks the downlink instruction mutual exclusion lock, and returns to step 201.

If, in step 304, the data processing module puts the uplink response into the uplink response buffer, step 209 may specifically be: the data processing module analyzes the uplink response in the uplink response buffer to obtain the uplink response valid data in the uplink response, uses the uplink response valid data in the uplink response as an uplink response result, returns the uplink response result to the application module, unlocks the downlink instruction mutual exclusion lock, and returns to step 201.

Step 210: the data processing module obtains the uplink delay application time according to the data in the uplink delay application buffer, resets the timeout time according to the uplink delay application time, clears the uplink delay application buffer, and returns to step 206;

step 211: the data processing module obtains a downlink response according to the request for sending the downlink response, sends the downlink response to the bluetooth device through the operating system, and returns to step 201.

Specifically, the data processing module obtains downlink response valid data from a downlink response sending request, organizes a downlink response including the downlink response valid data according to a preset protocol, and calls a system sending function of an operating system to send the downlink response to the bluetooth device.

Specifically, the data processing module obtains downlink response valid data from a downlink response sending request, sets a seventh preset value on a first byte in the downlink response according to a preset protocol, sets a fourth preset value on a second byte in the downlink response, sets the length of the downlink response valid data on a third byte and a fourth byte in the downlink response, sets the downlink response valid data behind the fourth byte, calculates data between the second byte and the downlink response valid data in the downlink response according to a preset algorithm to obtain a downlink response check value, sets the downlink response check value behind the downlink response valid data to obtain a downlink response including the downlink response valid data, and sends the downlink response to the bluetooth device by using a serial queue.

For example: the data processing module obtains downlink response valid data 04 from a downlink response sending request, sets a seventh preset value 3C on a first byte in the downlink response according to a preset protocol, sets a fourth preset value 02 on a second byte in the downlink response, sets data on a third byte and a fourth byte of the downlink response according to 1 byte of the downlink response valid data, sets the downlink response valid data behind the fourth byte, calculates data '02000104' between the second byte and the downlink response valid data in the downlink response according to a preset algorithm to obtain a downlink response check value 07, sets the downlink response check value behind the downlink response valid data to obtain a downlink response '3C 0200010407' comprising the downlink response valid data, and the data processing module sends the downlink response to the Bluetooth device by using a serial queue.

Step 301: the data processing module judges whether data exists in the receiving buffer area, if so, the step 302 is executed, otherwise, the step 308 is executed;

step 302: the data processing module starts to acquire uplink data from a first position in the receiving buffer area, judges whether legal uplink data is acquired, and executes step 303 if the legal uplink data is acquired; otherwise, removing the data at the first position in the receiving buffer, and returning to step 301;

preferably, the data of the first position in the receive buffer is the data on the first byte in the receive buffer.

Step 302 is shown in fig. 3, and specifically includes:

step 3021: the data processing module acquires data on a first byte in the receiving buffer area, judges whether the data on the first byte in the data in the receiving buffer area conforms to a protocol header of a preset protocol or not, and if so, executes step 3022; otherwise, removing the data on the first byte in the data in the receiving buffer, and returning to step 301;

in this embodiment, data on a first byte of a protocol header of uplink data specified by a preset protocol is a first preset value, a second preset value, or a third preset value. Preferably, the first preset value is 5A; the second preset value is C3; the third preset value is 53.

Specifically, the data processing module acquires data on a first byte in the receiving buffer, and determines whether the data on the first byte in the data in the receiving buffer is a first preset value, a second preset value or a third preset value, and if so, determines that the data on the first byte in the uplink data conforms to a protocol header of a preset protocol; otherwise, judging that the data on the first byte in the uplink data does not conform to the protocol header of the preset protocol.

For example: the data processing module determines that the data "00" on the first byte in the data "005 a 02000104075A F2B 84A" in the receiving buffer does not conform to the protocol header of the preset protocol, removes the data "00" on the first byte in the data "005 a 02000104075A F2B 84A" in the receiving buffer, and returns to step 301; when the determination in step 301 is yes, the data processing module determines that the data "5A" on the first byte in the data "5A 02000104075A F2B 84A" in the receiving buffer is the first preset value, and then determines that the data on the first byte in the data in the receiving buffer conforms to the protocol header of the preset protocol.

Step 3022: the data processing module acquires current data to be verified and current check bit data from the data in the receiving buffer, judges whether the data to be verified and the current check bit data conform to a preset protocol, if so, takes the data between the data on the first byte in the receiving buffer and the data on the current check bit as legal uplink data, and executes step 303; otherwise, the data on the first byte in the data in the receiving buffer is removed, and the step 301 is returned.

Specifically, the data processing module obtains current data to be verified and current check bit data from data in the receiving buffer according to a preset protocol, performs operation on the current data to be verified according to a preset algorithm to obtain a first operation value, determines whether the first operation value is matched with the current check bit data, and if so, takes data between a first byte and the current check bit data as legal uplink data, and executes step 303; otherwise, the data on the first byte in the data in the receiving buffer is removed, and the step 301 is returned.

For example: the data processing module obtains current data to be verified "02000104" and current check bit data "07" from data "5 a 02000104075A F2B 84A" in the receiving buffer according to a preset protocol, performs xor operation from the beginning of the data to be verified "02" to the end of the data "04" according to a preset algorithm to obtain a first operation value "07", determines that the first operation value "07" matches the current check bit data "07", determines that data after a first byte in the receiving buffer includes data meeting the preset protocol, and performs step 303 by using the data "5 a 0200010407" between the first byte and the current check bit data as uplink data.

The data processing module acquires current data to be verified and current check bit data from data in the receiving buffer according to a preset protocol, and the method specifically comprises the following steps: the data processing module judges the type of the data on the first byte of the data in the receiving buffer, and if the data on the first byte of the receiving buffer is a first preset value, the step h1 is executed; if the data on the first byte in the receiving buffer is the second preset value or the third preset value, executing step h 2;

step h 1: the data processing module judges the type of the data on the second byte of the data in the receiving buffer, if the data on the second byte of the data in the receiving buffer is a fourth preset value, if yes, the step h2 is executed; if the data on the second byte in the data in the receiving buffer is the fifth preset value, executing step h 3;

preferably, the fourth preset value is 02 and the fifth preset value F2.

Step h 2: the data processing module acquires data on a third byte and a fourth byte in the data in the receiving buffer area, and takes the data as the byte length of current effective data, acquires data after the fourth byte and with the data length being the byte length of the current effective data, and takes the data as the current effective data, takes the data on the second byte, the third byte and the fourth byte and the current effective data as current data to be verified, and takes the data on a first byte after the effective data as current check bit data.

Step h 3: the data processing module acquires the data length after the first byte and takes the data length as data with a first preset length, the data on the last byte in the acquired data is taken as current check bit data, and the acquired data except the current check bit data is taken as current data to be verified.

Preferably, the first preset length is 3 bytes.

For example: if the data in the receiving buffer is "5A 02000104075A F2B 84A", the data processing module determines that the data "5A" on the first byte in the data "5A 02000104075A F2B 84A" in the receiving buffer is the first preset value, the data processing module continues to execute step h1, determines that the data on the second byte in the data in the receiving buffer is the fourth preset value 02, and continues to execute step h 2; the data processing module acquires data "0001" on the third and fourth bytes in the data in the receiving buffer, and the data "0001" on the third and fourth bytes is used as the byte length of the currently valid data, acquires data after the fourth byte "01" and having the data length of the currently valid data byte (namely, one byte), that is, acquires data "04", and requests "04" as the currently valid data, takes data "02", "00", "01" and the currently valid data "04" on the second byte, the third byte and the fourth byte as data to be verified, and takes data "07" on the first byte after the currently valid data "04" as current check bit data.

If the data in the receiving buffer is "5A F2B 84A", the data processing module determines that the data "5A" on the first byte in the data "5A F2B 84A" in the receiving buffer is the first preset value, the data processing module continues to execute step h1, determines that the data on the second byte in the data in the receiving buffer is the fifth preset value F2, and continues to execute step h 3; the data processing module acquires data with a data length of a first preset length (i.e., 3 bytes) after the data "5A" on the first byte, takes the data "4A" on the last byte in the acquired data "F2B 84A" as the current parity data, and takes the acquired data "F2B 8" except the current parity data as the current data to be verified.

Step 303: the data processing module judges the type of the uplink data, and if the uplink data is an uplink response, step 304 is executed; if the uplink data is an uplink delay application, go to step 305; if the uplink data is an uplink command, go to step 306; if the uplink data is the uplink notification, go to step 307;

specifically, the data processing module determines a type of data on a first byte in the uplink data, determines a type of data on a second byte in the uplink data if the data on the first byte in the uplink data is a first preset value, determines the uplink data as an uplink response if the data on the second byte in the uplink data is a fourth preset value, and determines the uplink data as an uplink delay application if the data on the second byte in the uplink data is a fifth preset value; if the data on the first byte in the uplink data is a second preset value, the uplink data is an uplink instruction; and if the data on the first byte in the uplink data is the third preset value, the uplink data is the uplink notification.

For example: if the uplink data acquired by the data processing module is "5A 0200010407", the data processing module judges that the data on the first byte in the uplink data "5A 0200010407" is the first preset value "5A", judges the type of the data on the second byte in the uplink data, and judges that the data on the second byte in the uplink data "5A 0200010407" is the fourth preset value "02", and judges that the uplink data "5A 0200010407" is an uplink response;

if the uplink data acquired by the data processing module is "5A F2B 84A", the data processing module judges that the data on the first byte in the uplink data "5A F2B 84A" is a first preset value "5A", judges the type of the data on the second byte in the uplink data, and judges that the uplink data "5A F2B 84A" is an uplink delay application if the data "F2" on the second byte in the uplink data "5A F2B 84A" is a fifth preset value;

if the uplink data acquired by the data processing module is "C3020002010203", the data processing module determines that the data on the first byte in the uplink data "C3020002010203" is the second preset value "C3", and determines that the uplink data "C3020002010203" is an uplink instruction;

if the uplink data acquired by the data processing module is "530200010103", the data processing module determines that the data on the first byte in the uplink data "530200010103" is the third preset value "53", and determines that the uplink data "530200010103" is the uplink notification.

Step 304: the data processing module puts the uplink response or the uplink response valid data in the uplink response into the uplink response buffer area, removes the uplink response in the receiving buffer area, and returns to step 301;

if the data processing module puts the uplink response valid data in the uplink response into the uplink response buffer, step 304 specifically includes: the data processing module analyzes the uplink response, acquires uplink response valid data in the uplink response, puts the uplink response valid data in the uplink response into an uplink response buffer, removes the uplink response in the receiving buffer, and returns to step 301.

More specifically, the data processing module parses the uplink response, obtains data on the third byte and the fourth byte in the uplink response, and uses the data as the byte length of the uplink response valid data, obtains data after the fourth byte and with the data length being the byte length of the uplink response valid data, and uses the data as the uplink response valid data, puts the uplink response valid data into the uplink response buffer, removes the uplink response in the receiving buffer, and returns to step 301.

For example: the data processing module analyzes the uplink response "5 a 0200010407", acquires data "0001" on the third and fourth bytes in the uplink response, takes the data as the byte length of the uplink response valid data, acquires data "04" after the fourth byte and with the data length of 1 byte, takes the data as the uplink response valid data, takes the uplink response valid data as the uplink response result, puts the uplink response valid data "04" into the uplink response buffer, removes the uplink response in the receiving buffer, and returns to step 301.

Step 305: the data processing module obtains uplink delay application time according to the uplink delay application, puts the uplink delay application time into an uplink delay application buffer, removes the uplink delay application in the receiving buffer, and returns to step 301;

for example: the data processing module obtains the uplink delay application time as a first preset time according to the uplink delay application "5A F2B 84A", the first preset time is put into the uplink delay application buffer, the uplink delay application in the receiving buffer is removed, and the step 301 is returned to.

Preferably, the first preset time is 3 seconds.

This step can also be replaced by: the data processing module puts the uplink delay application into the uplink delay application buffer, removes the uplink delay application in the receiving buffer, and returns to step 301;

correspondingly, step 210 specifically includes: the data processing module obtains the uplink delay application time according to the uplink delay application in the uplink delay application buffer, resets the timeout time according to the uplink delay application time, and returns to step 206.

Step 306: the data processing module obtains an uplink instruction result according to the uplink instruction, sends the uplink instruction result to the application module, removes the uplink instruction in the receiving buffer area, and returns to the step 301;

specifically, the data processing module analyzes the uplink instruction, obtains effective data in the uplink instruction, uses the effective data in the uplink instruction as an uplink instruction result, returns the uplink instruction result to the application module through the second callback function, removes the uplink instruction in the receiving buffer, and returns to step 301.

More specifically, the data processing module parses the uplink instruction, obtains data on the third byte and the fourth byte in the uplink instruction, and takes the data as the byte length of the effective data in the uplink instruction, obtains data with the data length being the byte length of the effective data in the uplink instruction from the fourth byte, and takes the data as the effective data in the uplink instruction, takes the effective data in the uplink instruction as the result of the uplink instruction, and returns the result of the uplink instruction to the application module through the second callback function, removes the uplink instruction in the receiving buffer, and returns to step 301.

For example: the data processing module analyzes the uplink instruction "C3020002010203", acquires data "0002" on the third and fourth bytes in the uplink instruction, and uses the data "0002" as the byte length of the valid data in the uplink instruction, acquires data "0102" with a data length of 2 bytes from the fourth byte onward, and uses the data "0102" as the valid data in the uplink instruction, and uses the valid data in the uplink instruction as the result of the uplink instruction, and returns the result of the uplink instruction to the application module through the second callback function, removes the uplink instruction in the receiving buffer, and returns to step 301.

It should be noted that, before the data processing module returns the result of the uplink instruction to the application module through the second callback function, the method further includes: the application module registers a second callback function with the data processing module, and accordingly: and when the data processing module analyzes the uplink instruction, effective data in the uplink instruction is obtained, and the effective data in the uplink instruction is used as an uplink instruction result, and the uplink instruction result is returned to the application module through the second callback function.

Step 307: the data processing module obtains an uplink notification result according to the uplink notification, returns the uplink notification result to the application module, removes the uplink notification in the receiving buffer, and returns to step 301;

specifically, the data processing module analyzes the uplink notification, acquires the valid data in the uplink notification, uses the valid data in the uplink notification as an uplink notification result according to the valid data in the uplink notification, and returns the uplink notification result to the application module through the third callback function.

More specifically, the data processing module analyzes the uplink notification, acquires data on the third and fourth bytes in the uplink notification, and uses the data as the byte length of the valid data, acquires data with the data length being the byte length of the valid data from the fourth byte, and uses the data as the valid data, and returns the valid data to the application module through the third callback function.

For example, the data processing module parses the upstream notification "530200010103," obtains the data "0001" in the third and fourth bytes in the upstream notification, takes it as the byte length of the valid data, obtains the data "01" whose data length is the byte length of the valid data from the fourth byte onward, takes it as the valid data, and passes the valid data "01" through the third callback function dwdevent _ handle (dword dweventid); and returning the data to the application module, and acquiring a notification event 'low electric quantity' corresponding to the effective data '01' by the application module.

It should be noted that before the data processing module returns the notification event corresponding to the valid data to the application module through the third callback function, the method further includes: the application module registers a third callback function with the data processing module, and accordingly: and when the data processing module analyzes the uplink notification and acquires the effective data in the uplink notification, returning the effective data to the application module through a third callback function.

Step 308: the data processing module detects whether the data adding flag bit is set, if so, the data adding flag bit is reset, and the step 301 or 302 is returned; otherwise, return to step 308;

in this embodiment, step 203 may further specifically be: the data processing module obtains a downlink instruction from the request for sending the downlink instruction, and the data processing module sends the downlink instruction to the Bluetooth device through the operating system by using the serial queue; step 304 may also be replaced with: the data processing module takes the uplink response as an uplink response result, puts the uplink response result into an uplink response buffer area, removes the uplink response in the receiving buffer area, and returns to the step 301; step 209 may also specifically be: the data processing module takes the data in the uplink response buffer area as an uplink response result, returns the uplink response result to the application module, unlocks the downlink instruction mutual exclusion lock, and returns to step 201; step 306 may also specifically be: the data processing module takes the uplink instruction as an uplink instruction result, sends the uplink instruction result to the application module, removes the uplink instruction in the receiving buffer area, and returns to the step 301; step 211 may also specifically be: the data processing module obtains the downlink response from the downlink response request, sends the downlink response to the bluetooth device through the operating system, and returns to step 201. Step 307 may further specifically be: the data processing module takes the uplink notification as an uplink notification result, returns the uplink notification result to the application module, removes the uplink notification in the receiving buffer, and returns to step 301.

In this embodiment, if the data processing module receives the bluetooth data from the bluetooth device of the operating system in the data receiving thread, the data processing module continues to execute step 301 in the data receiving thread after adding the bluetooth data from the bluetooth device to the receiving buffer by using the serial queue; after the determination in step 301 is negative, the data reception thread continues to wait for the reception of bluetooth data from the bluetooth device of the operating system.

Accordingly, step 302 may also be: the data processing module acquires uplink data from the receiving buffer area, judges whether legal uplink data is acquired or not, and executes step 303 if the legal uplink data is acquired; otherwise, the data in the receiving buffer is removed, and the data receiving thread is continuously waited for receiving the Bluetooth data from the Bluetooth device of the operating system.

In this embodiment, step 208 may also be performed after step 206; accordingly, step 303 is replaced with: the data processing module judges the type of the uplink data, and if the uplink data is an uplink response, step 304 is executed; if the uplink data is an uplink command, go to step 306; if the uplink data is the uplink notification, go to step 307.

In this embodiment, after the data processing module sends the uplink instruction to the application module, the application module may also send a request for sending a downlink delay application to the data processing module; accordingly, step 201 may further include: if receiving a request for sending a downlink delay application from the application module, the data processing module organizes the downlink delay application, sends the downlink delay application to the bluetooth device, and returns to step 201.

Specifically, after the data processing module receives a request for sending a downlink delay application from the application module through its own third receiving interface in the data sending thread, the data processing module organizes the downlink delay application, sends the downlink delay application to the bluetooth device, and returns to step 201.

For example: specifically, after the data processing module receives a downlink delay application sending request from the application module through its own third receiving interface assigned int sendTimeout in the data sending thread, the data processing module organizes the downlink delay application "3C F2B 84A", sends the downlink delay application to the bluetooth device, and returns to step 201.

In the method for processing bluetooth data by a mobile terminal provided by this embodiment, after receiving bluetooth data from a bluetooth device of an operating system, a data processing module in the mobile terminal puts the received bluetooth data into a receiving buffer in sequence, and parses the received data according to a byte situation, if it is determined by a preset protocol that data in a first byte or a protocol data format behind the first byte is incorrect, the byte data in the first byte is discarded, and the judgment is performed backwards in sequence until uplink data conforming to the preset protocol is found and the type of the data is distinguished: if the uplink data is the uplink response, the uplink response or the uplink response effective data in the uplink response is put into an uplink response buffer zone; if a downlink instruction sending request from the application module is received, obtaining a downlink instruction according to the downlink instruction request, sending the downlink instruction to the Bluetooth equipment through the operating system, then detecting whether data exist in the uplink response buffer area, if so, obtaining an uplink response result according to the data in the uplink response buffer area, and returning the uplink response result to the application module; if the uplink data is an uplink instruction, adopting a callback mode according to an uplink instruction result obtained by the uplink instruction, namely returning the uplink instruction result to the application module through a second callback function, obtaining a downlink response corresponding to the uplink instruction according to a downlink response sending request of the application module, and sending the downlink response to the Bluetooth equipment through the operating system; if the uplink data is the uplink notification, an uplink notification result is obtained according to the uplink notification, and a callback mode is adopted, namely the uplink notification result is returned to the application module through a third callback function, so that the mobile terminal can actively send a downlink instruction to the Bluetooth device, receive an uplink response from the Bluetooth device, passively respond to the uplink instruction from the Bluetooth device and send a corresponding downlink response to the Bluetooth device, the accuracy and reliability of the data of the mobile terminal in the data processing process can be ensured, and the beneficial effects of reducing the power consumption of the mobile terminal and optimizing the performance of the mobile terminal are achieved.
