8. Bluetooth Module Application Examples
BLE-DK and WT-Demo-Kit are auxiliary tools designed by Wireless-Tag for the simple
application of its nRF51822 and nRF52832 series of BLE transparent transmission modules.
The Bluetooth module can be easily connected to PC through the DEMO-Kit. The module
can be configured with AT commands and some basic parameters of the Bluetooth
module can be reset through the serial port debugging tool on the PC side. As a slave
device, the Bluetooth module can be searched and paired by the Bluetooth master of the
mobile device APP. After pairing, data can be input to the Bluetooth module through the
serial debugging tool. The Bluetooth module transmits the data to the Bluetooth master
terminal, and at the same time, it transmits the data returned by Bluetooth master
