| .. zephyr:code-sample:: ble_central_hr |
| :name: Heart-rate Monitor (Central) |
| :relevant-api: bluetooth |
| |
| Connect to a Bluetooth LE heart-rate monitor and read heart-rate measurements. |
| |
| Overview |
| ******** |
| |
| Similar to the :zephyr:code-sample:`ble_central` sample, except that this |
| application specifically looks for heart-rate monitors and reports the |
| heart-rate readings once connected. |
| |
| 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: |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/bluetooth/central_hr |
| :board: <board> |
| :goals: build flash |
| :compact: |
| |
| After flashing, the sample scans for peripherals advertising the Heart Rate |
| Service (HRS). When one is found, it connects and subscribes to Heart Rate |
| Measurement notifications. Use the :zephyr:code-sample:`ble_peripheral` sample |
| on a second board, or any Bluetooth LE heart rate monitor, as the peripheral. |
