WT51822-S4AT is a high-performance, low-power (Bluetooth Low Energy) RF transceiver system module using Nordic’s Bluetooth 4.1 nRF51822 as the core processor. 18.5*9.1*2.0, suitable for most application scenarios with high volume requirements, the module integrates a complete standard low-power Bluetooth 4.1 (compatible with 4.0) protocol stack S110 driver. describe

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