Peripheral NUS
Overview
This sample demonstrates the usage of the NUS service (Nordic UART Service) as a serial endpoint to exchange data. In this case, the sample assumes the data is UTF-8 encoded, but it may be binary data. Once the user connects to the device and subscribes to the TX characteristic, it will start receiving periodic notifications with “Hello World!n”.
Requirements
BlueZ running on the host, or
A board with Bluetooth LE support
Building and Running
Build and flash the sample as follows, replacing <board> with your target board:
west build -b <board> samples/bluetooth/peripheral_nus
west flash
After flashing, use a Bluetooth scanner app (e.g. nRF Connect) to connect to the device
and subscribe to the NUS TX characteristic. The device will send periodic
Hello World! notifications.
