Bluetooth

 low energy heart rate monitor demo

This section shows you how to program a heart rate monitor demo on top of a SoftDevice that will send data 
on a 

Bluetooth

 link from the heart rate monitor to the Master Control Panel.

Download and program the SoftDevice

Type the product key (included with the Development Kit) into the 

Product Key

 field in My Page to 

download the S110 nRF51822 SoftDevice.

Follow these steps to program your device:

1. Open nRFgo Studio.
2. In the Device Manager select the motherboard your module is connected to.
3. Select the module.

4. If you have more than one SEGGER debugger connected, you need to select which one you want 

to use.

5. Select the 

Program SoftDevice

 tab.

6. Click
