TIMER2 running at 500us interval with ANT stack enabledhttps://devzone.nordicsemi.com/f/nordic-q-a/6459/timer2-running-at-500us-interval-with-ant-stack-enabledI have TIMER2 running at 500us interval. ANT is working as 100Hz master. Understood softdevice will affect the timing and cause some latency. I am guessing it is delaying the TIMER2_IRQHandler response by more than 500us which is enough to miss a TIMER2en-USTelligent Community 13Tue, 14 Apr 2015 13:15:06 GMTRE: TIMER2 running at 500us interval with ANT stack enabledhttps://devzone.nordicsemi.com/thread/22533?ContentTypeID=1Tue, 14 Apr 2015 13:15:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a81b5ed2-225d-44d3-a669-c82484562c99Stefan Birnir Sverrisson<p>Hi Paul</p> <p>I suspect you are correct, the ANT communication may be blocking the CPU for too long. Are you using S210 4.0.1? If so, look at the <a href="https://www.nordicsemi.com/eng/nordic/Products/nRF51422/S210-SDS/20359">S210 SDS 2.0</a> sections 11.2 and 11.3 for CPU availability. If your processing time for each TIMER2 interrupt is less than 100us, you could set the interrupt priority to APP_HIGH to see if that helps.</p><div style="clear:both;"></div>
