OK to use app_timer before nrf_sdh_enable_request()?

[charles]

SDK v14.0, SD132 v5.0.0

We're creating and starting app_timer instances before we enable SoftDevice via nrf_sdh_enable_request(). It seems to work, but I remember that SoftDevice takes ownership of RTC0. Is this safe to do? Should we enable SD before starting timers?

Hi, 

App timer uses RTC1 so it shouldn't be a problem as long as you start the LF clock source first. RTC0 is reserved for the Softdevice as you said.

Thanks for the quick response!
