There is unfortunately no direct cycle counter in the nRF51822, so this is something you'll have to implement yourself, either with one of the 16 MHz timers, or by doing GPIO toggling.

Yes I am running the SoftDevice and my code runs at 100Hz through the app_timer() scheduler.

Hi,

I think we can use on-chip hardware timer/RTC instead. Do you use SoftDevice during profiling?
