Bluetooth: Peripheral Heart Rate Monitor with Coded PHY¶
The Peripheral Heart Rate Monitor with Coded PHY offers similar functionality to the Bluetooth: Peripheral HR sample from Zephyr. However, this sample supports LE Coded PHY.
Overview¶
The sample demonstrates a basic Bluetooth LE Peripheral role functionality that exposes the Heart Rate GATT Service with LE Coded PHY support. Once it connects to a Central device, it generates dummy heart rate values. It can be used together with the Bluetooth: Central Heart Rate Monitor with Coded PHY sample.
Requirements¶
The sample supports the following development kits:
Hardware platforms |
PCA |
Board name |
Build target |
---|---|---|---|
PCA10095 |
|
||
PCA10059 |
|
||
PCA10056 |
|
The sample also requires:
A device running a Heart Rate Server with LE Coded PHY support to connect to. For example, another development kit running the Bluetooth: Central Heart Rate Monitor with Coded PHY sample.
Building and Running¶
This sample can be found under samples/bluetooth/peripheral_hr_coded
in the nRF Connect SDK folder structure.
See Building and programming a sample application for information about how to build and program the application.
Testing¶
After programming the sample to your board, you can test it by connecting to another board that runs the Bluetooth: Central Heart Rate Monitor with Coded PHY.
Connect to the kit that runs this sample with a terminal emulator (for example, PuTTY). See How to connect with PuTTY for the required settings.
Reset the board.
Program the other board with the Bluetooth: Central Heart Rate Monitor with Coded PHY.
Wait until the Coded advertiser is detected by the Central. In the terminal window, check for information similar to the following:
Connected: xx.xx.xx.xx.xx.xx (random), tx_phy 4, rx_phy 4
In the terminal window, observe that notifications are enabled:
<inf> hrs: HRS notifications enabled
