8. Bluetooth Module Application Examples

1. Auxiliary tool BLE-DK
WT-Demo-Kit is an auxiliary tool designed by our company for the simple application of
nRF51822, nRF52810, nRF52832, nRF52840 series BLE Bluetooth 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 found and connected by the Bluetooth
master. When the connection is successful, data can be input to the Bluetooth module
through the serial debugging tool, and the Bluetooth module transmits this data to the
Bluetooth master. At the same time, the data returned by the Bluetooth master received
by the Bluetooth module can be transferred to the serial port debugging tool. Developers
can conveniently and simply view the contents of data transmission between the
Bluetooth module and the Bluetooth master terminal.

2. Connection method of DEMO-Kit and Bluetooth module
The interface of DEMO-Kit is the currently popular XBee module interface. The Bluetooth
module and Kit tool are connected through the XBee adapter board, and the module is
welded on the corresponding XBee adapter board, and then the adapter board is inserted
into the Kit tool.
