The connectivity firmware will act as a serialized controller for the softdevice. The heart rate application is implemented in the&nbsp;hear_rate_monitor.js script. Flash the connectivity firmware, run the script, and&nbsp;connect to the device with&nbsp;the HRM app in nRF Toolbox on&nbsp;your phone to check that it is working.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
