Description

A system and method for detecting normal communication of low-power bluetooth

technical field

The invention belongs to the field of communication technology, and further relates to a system and method for detecting normal communication of low-power bluetooth in the field of electronic communication technology. The invention can be used to detect whether the low-power bluetooth produced by different manufacturers has a normal communication function.

Background technique

Bluetooth, as a short-distance communication method, is more and more widely used. Especially the use of Bluetooth Low Energy on various smart wearable devices. The terminal bluetooth is used as the master end, and the low-power bluetooth device is used as the slave end to realize the communication between the mobile terminal and the low-power bluetooth device. However, Bluetooth low-power devices are easily damaged during use. Currently, the detection method for Bluetooth integrity only provides a single method for each manufacturer's Bluetooth low-power devices. This will lead to complex operation, increased user cost, and great inconvenience.

Beijing Qingchuan Technology Co., Ltd. discloses a Bluetooth connection system in the patent "A Bluetooth connection method, Bluetooth device and system" (application number: 201610007214.0, publication number: CN105490713A), which includes: Bluetooth devices, Bluetooth equipment. The shortcomings of this system are: the data transmission between the master and the slave is realized, but it cannot adapt to different write characteristic values and notification characteristic values;

Chuangda Software Co., Ltd. discloses a method and device for Bluetooth connection in its patent application "A Bluetooth connection method and device" (application number: 201610757801.1, publication (announcement) number: CN106162535A). Including, after starting the Bluetooth function, start to scan the Bluetooth devices that exist around, and at the same time, judge whether the electronic device has the logo of the Bluetooth device that has been connected before. If the judgment result is yes, it means that the electronic device has been connected to the Bluetooth device before, and stop scanning .

Step 13, judging whether the notification feature value input by the master terminal is the same as the notification feature value of the slave terminal, if yes, go to step 17, otherwise go to step 11.

Step 14, the slave end sends a message to the master end.

The master end sends the notification characteristic value to the slave end device, so that the master end can receive the notification from the slave end. Write the data that needs to be sent to the master on the serial port assistant software, and through Bluetooth wireless transmission, analyze and write the transmission data of the slave device carried in the characteristic value on the master.

Step 15, judge whether the data parsed by the master end is the same as the data sent by the slave end, if yes, execute step 16, otherwise execute step 17.
