peripheral_hr

Overview

Similar to the Peripheral sample, except that this application specifically exposes the HR (Heart Rate) GATT Service. Once a device connects it will generate dummy heart-rate values.

Requirements

  • A board with BLE support

  • nRF Toolbox APP or nRF Connect

Building and Running

Example Location：examples/bluetooth/peripheral_hr

compile, burn, and more, see：Quick Start Guide

Operation Instructions Translation

  1. Burn the firmware compiled from the peripheral_hr example onto the development board.

  2. On your smartphone, run the nRF Toolbox application
