The customer MCU is connected to the module through the UART port. After the module is started, it will automatically send thebroadcast code. The APP device as the master station can scan and search for the module’s broadcast to establish a connection.
After success, it can be connected to the mobile device APP through the serial port. Two-way communication connection, the user can exchange data or control the communication parameters of the module through the UART port. The meaning of the data is defined by the upper application user.
The mobile device can write to the module through the APP, and the data will be received by the module and pushed to the MCU through the UART. After the module receives the data packet from the client MCU serial port, it will automatically forward it to the mobile device.
