Softdevice consumes too much timehttps://devzone.nordicsemi.com/f/nordic-q-a/25669/softdevice-consumes-too-much-timeHello, I am using nrf52832 with SDK12 with gcc compiler. I have extended the ble_app_template example with 2 services. I have 1 timer interrupt using RTC(100 ms) and 1 timer interrupt using HF timer(20 micro secs). I am toggling a pin in HF timeren-USTelligent Community 13Wed, 04 Oct 2017 22:19:11 GMTRE: Softdevice consumes too much timehttps://devzone.nordicsemi.com/thread/101124?ContentTypeID=1Wed, 04 Oct 2017 22:19:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4d94c77e-f083-4139-9393-27df6870793ahimanshu pande<p>This was incredibly helpful.

I am reloading the NRF_TIMER2-&gt;CC[0] register every time in the interrupt handler. Basically, when there is a softdevice interruption(which is surely more than 20 micro secs), the current timer count has passed the loaded value in the compare register and hence it waits for an entire cycle(16 MHz i.e. nearly 4 ms) to interrupt again.</p> <p>Is there a way to have pre-interrupt and post-interrupt hooks for when softdevice takes control? I would like to adjust the timer count in those routines.</p> <p>I hope the explanation is clear.</p><div style="clear:both;"></div>RE: Softdevice consumes too much timehttps://devzone.nordicsemi.com/thread/101121?ContentTypeID=1Wed, 04 Oct 2017 12:54:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1e0e1d93-787a-4425-bbab-b9f4fedc78e1MartinBL<p>I&#39;m not sure I understand.
