Cannot get Heart Rate sample working

I am following nRF51822_Evaluation_Kit User_Guide v1.2.pdf (page #9) to run Heart Rate sample but I am unable to get an expected result (LED 0 should be lit) when I am pressing a Button 0, in addition, when I was trying to setup a breakpoint in the Main() - it was not hit. Note that I have SoftDevice programmed to my Evaluation Board - in nRFgo Studio I can see:

Region 0 (SoftDevice) Size: 80 kb Firmware: s110_nrf51822_6.0.0 (id:0x0049)

What could be wrong?

  • Eventually you were right because I just realized that I didn't have the latest available soft device - I had version 6 but there is a version 7 available as well, once I downloaded and programmed it I am now able to see an expected behavior, thank you.
