In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.
Fig. 1 is a schematic implementation flowchart of a bluetooth interaction method provided in an embodiment of the present application, and as shown in the figure, the method may include the following steps:
step S101, a Bluetooth connection request is initiated to the slave device.
In one embodiment, after initiating the bluetooth connection request to the slave device, the method further comprises:
detecting whether a Bluetooth connection is established with a slave device within a first preset time after a Bluetooth connection request is initiated to the slave device.
If the Bluetooth connection with the slave equipment is detected to be established within first preset time after the Bluetooth connection request is initiated to the slave equipment, initiating an initialization process to the slave equipment.
And if the Bluetooth connection with the slave equipment is detected not to be established within the first preset time after the Bluetooth connection request is initiated to the slave equipment, the Bluetooth connection request is initiated to the slave equipment again.
In practical application, the embodiment of the application is applied to the master device, the master device initiates a bluetooth connection request to the slave device, and detects whether the connection with the slave device is successfully established within a first preset time after the request is sent. Under the normal condition, the master device initiates a bluetooth connection request to the slave device and then can detect the time when the connection with the slave device is successfully established. In practical application, the first preset time can be manually preset according to actual conditions. It should be noted that the master device and the slave device are not used to define the slave relationship of the bluetooth device, and the bluetooth device initiating the bluetooth connection request may be the master device. Therefore, in practical applications, the roles of the master device and the slave device may be switched.
Step S102, after the Bluetooth connection is established with the slave device, initiating an initialization process to the slave device, and detecting whether the initialization process is successful.
In one embodiment, the initialization procedure includes at least one sub-procedure. The detecting whether the initialization process is successful includes:
and if any sub-process processing of the initialization process fails, judging that the initialization process fails.
And if any sub-process of the initialization process succeeds, processing the next sub-process.
And if all the sub-processes of the initialization process are successfully processed, judging that the initialization process is successful.
In one embodiment, the initialization process includes an authentication sub-process and a key agreement sub-process. It should be noted that, in practical application, the bluetooth connection process may further include other sub-processes, and the processing sequence of each sub-process may not be sequential, or may be performed according to a certain sequence. For example, the key agreement sub-process may be performed after the authentication sub-process.
Specific initialization process can be referred to fig. 2, fig. 2 is a schematic diagram of an initialization process provided in the embodiment of the present application, and as shown in the figure, the initialization process includes:
step S201, performing the sub-process processing, and detecting whether the information that the sub-process processing is successful is received within a second preset time after the sub-process processing.
Step S202, if the information that the sub-process processing is successful is not received within the second preset time after the sub-process processing, it is determined that the sub-process processing fails.
Step S203, if the information that the sub-process is successfully processed is received within the second preset time after the sub-process is processed, determining that the sub-process is successfully processed.
And the second preset time is the time for receiving the information of the success/failure of the sub-process processing after the sub-process is processed under the normal condition. In practical application, the second preset time can be preset manually according to practical conditions.
Illustratively, when the bluetooth initialization process is performed, the authentication sub-process is performed first, and whether the information of successful authentication is received is detected within a second preset time after the authentication sub-process is performed. And if the information of successful authentication is not received within the second preset time after the authentication subprocess is processed, the processing of the authentication subprocess fails. And if the information that the authentication sub-process is successfully processed is received within the second preset time after the authentication sub-process is processed, the authentication sub-process is successfully processed, and the key agreement sub-process is continuously processed. And detecting whether the information of successful key agreement is received or not within a third preset time after the key agreement sub-process is processed. If the information of successful key agreement is not received within the third preset time after the key agreement sub-process is processed, the processing of the key agreement process fails. And if the information that the key negotiation sub-process is successfully processed is received within the third preset time after the key negotiation sub-process is processed, the key negotiation sub-process is successfully processed, and the initialization is successful until the processing of the Bluetooth connection process is finished.
It should be noted that the first, second, and third of the first preset time, the second preset time, and the third preset time do not represent a sequence or a counting relationship, but are used to represent different preset times.
Step S103, if the initialization process fails, a Bluetooth connection request is initiated to the slave device again.
In an embodiment, after the initialization procedure fails, a failure reason may also be obtained, and if the failure reason is caused by abnormal communication, the bluetooth connection request is re-initiated to the slave device, where the failure reason caused by abnormal communication may be no response of the slave device or data confusion. And if the failure reason is not caused by the communication abnormity, the initialization process or the sub-process thereof is reinitiated.
In one embodiment, the number of retries may be preset, where the number of retries is the number of times of re-initiating the bluetooth connection request to the slave device, and when the number of retries is exceeded, the user is directly prompted for failure information.
In one embodiment, after detecting that the bluetooth connection is established with the slave device, the method further includes:
it is confirmed whether a timer associated with the bluetooth connection time has started.
And if the timer is not started, starting the timer, and setting the time of the timer as an initial value.
In practical application, after detecting that the connection with the slave device is successfully established, it needs to determine whether a timer is started, and if the timer is started, the master device performs the processing of the bluetooth connection process before the bluetooth connection, and the processing of the bluetooth initialization process fails; at this time, the timer is only required to continuously record the connection time. If the timer is not started, the Bluetooth connection is the first connection, and if the Bluetooth connection is the first connection, the timer needs to be started, the time of the timer is set to be an initial value, and the connection time is recorded by the timer. Wherein, the initial value can be 00.
In one embodiment, before initiating a bluetooth connection request to the slave device again if the initialization procedure fails, the method further includes:
and acquiring the current time of the timer.
And if the current time of the timer is greater than or equal to the preset value, judging that the initialization process fails.
And if the current time of the timer is less than the preset value, initiating a Bluetooth connection request to the slave equipment again.
In practical application, the preset value can be manually preset, the preset value is used for judging whether the time recorded by the timer is overtime, and if the time is not overtime, the Bluetooth connection request is initiated to the slave equipment again; if it times out, initialization fails. Therefore, the time of the initialization process in the Bluetooth interaction process is controlled. Assuming that the bluetooth initialization process requires 1s, the preset value is set to 1. After the master device and the slave device are successfully connected, the timer starts to count time, and when any sub-process in the bluetooth initialization process is processed each time, the current time of the timer needs to be judged and acquired, and whether the time is overtime or not is judged. If the time exceeds 1s, the initialization fails, and if the time does not exceed 1s, the subsequent process is performed.
Illustratively, in an example of performing the processing of the bluetooth initialization procedure, if the processing of the authentication sub-procedure fails, the current time of the timer is acquired, and if the time is not exceeded, the bluetooth connection request is initiated to the slave again; if time out, initialization fails. Similarly, if the processing of the key negotiation subprocess fails, the current time of the timer is acquired, and if the time is not overtime, a bluetooth connection request is initiated to the slave equipment again; if time out, initialization fails.
In the embodiment of the application, after the Bluetooth connection is established with the slave equipment, an initialization process is initiated to the slave equipment, and whether the initialization process is successful or not is detected; and if the initialization process fails, initiating a Bluetooth connection request to the slave equipment again. By the method, the occurrence probability of initialization failure is effectively avoided, and the success rate of Bluetooth interaction is effectively increased.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
