Because the BLE product is characterized by adopting low-frequency communication, the power consumption of the product is reduced, and the purpose of long-time use is achieved. However, in some applications, when an emergency or an important event occurs, the BLE product needs to be connected with the host quickly to complete a specific function. But the characteristics of BLE product adopt low frequency communication, cause it to take a long time just can establish connection with the host computer to can not satisfy the demand of quick establishment connection.
Such as: before being put into the market, the BLE product needs to be configured and detected in operation parameters, so that the product can be guaranteed to be correctly and reliably operated in the hands of a user. In the semi-finished product stage, an interface can be reserved on the circuit board and is connected with a testing device through a thimble, so that the configuration and the detection of a BLE product are realized; however, in the finished product stage, how to ensure that the appearance of the BLE product is not damaged, and meanwhile, the rapid configuration and detection of large-batch BLE products become an important part in the production process.
Referring to fig. 1 and fig. 2, fig. 1 and fig. 2 respectively show connection block diagrams of a possible bluetooth electronic device 10. The bluetooth electronic device 10 provided by the embodiment of the present application includes a controller 101 and a bluetooth apparatus 102.
As shown in fig. 1 and 2, the controller 101 is connected to the bluetooth device 102. Possibly, the controller 101 is also electrically connected to the sensing module 104 or the keys 103. The embodiment of the present application further provides a connection block diagram of a possible bluetooth electronic device 10, please refer to fig. 3, in which the controller 101 is electrically connected to the sensing module 104 and the key 103, respectively.
The controller 101 is configured to send a cycle switching instruction to the bluetooth device 102 when acquiring a trigger signal, where the trigger signal is a key signal or a sensing signal sent by the sensing module 104.
Specifically, the key signal is a signal transmitted by the key 103. The keys 103 may be physical keys or inductive keys to facilitate operation.
The bluetooth device 102 is configured to broadcast a corresponding bluetooth signal with a first period after receiving the period switching instruction, where the first period is less than the working period of the bluetooth device 102, and the bluetooth signal includes the identity information of the bluetooth device 102.
In particular, existing bluetooth low energy BLE products have long broadcast periods, which may be several seconds or even minutes. When the BLE product establishes connection with other terminals through bluetooth broadcasting, 1 cycle or several cycles need to be waited, thereby resulting in long waiting time.
In the scheme of the application, by changing the length of the broadcast period (namely, the broadcast frequency), the period time can be shortened to 100ms, and even can be smaller. Thus, even after waiting for several cycles, other terminals may search for the bluetooth broadcast to establish a connection with the bluetooth device 102, wherein the time interval is relatively short.
To sum up, in the bluetooth electronic device provided in the embodiment of the present application, when the trigger signal is obtained through the controller, the controller sends a cycle switching instruction to the bluetooth apparatus; so that the bluetooth device broadcasts a corresponding bluetooth signal including identity information of the bluetooth device at a first period that is less than the duty cycle of the bluetooth device. Because the first period is less than the work period, the Bluetooth signals which can be sent more times are broadcast in the first period in the same time period, so that other terminals can scan the Bluetooth signals containing the identity information of the Bluetooth device, and the other terminals can establish connection with the Bluetooth electronic equipment containing the Bluetooth device, thereby achieving the purposes of quick connection and matching.

In particular, the bluetooth electronic device 10 may be a health bracelet. The pulse sensor is used for detecting a pulse signal of the wearer and transmitting the detected pulse signal to the controller 101. When the pulse signal is less than the first threshold or greater than the second threshold, it indicates that the vital signs of the wearer are abnormal. The bluetooth electronic device 10 needs to alarm, and in order to quickly establish a connection with another terminal, the controller 101 sends a cycle switching command to the bluetooth apparatus, so that the bluetooth apparatus broadcasts a corresponding bluetooth signal including identity information of the bluetooth apparatus at a first cycle that is less than a duty cycle of the bluetooth apparatus.
On the basis of fig. 2 or fig. 3, for the above-mentioned sensing module 104, the following is referred to as a possible example.
The sensing module 104 is a temperature sensor, and the trigger signal is a temperature signal smaller than a third threshold or larger than a fourth threshold.
Specifically, the temperature sensor is configured to detect a temperature signal of the current environment and send the detected temperature signal to the controller 101. When the temperature signal is smaller than the third threshold or larger than the fourth threshold, the current environment is indicated to have potential safety hazard or be unfavorable for activities. The bluetooth electronic device 10 needs to alarm, and in order to quickly establish a connection with another terminal, the controller 101 sends a cycle switching command to the bluetooth apparatus, so that the bluetooth apparatus broadcasts a corresponding bluetooth signal including identity information of the bluetooth apparatus at a first cycle that is less than a duty cycle of the bluetooth apparatus.
Possibly, the sensing module 104 may also be an infrared sensor or a biosensor, etc. When the infrared sensor or the biosensor detects a corresponding signal, a trigger signal is sent to the controller 101, so that the controller 101 sends a cycle switching instruction to the bluetooth device.
