app_timer SHUTDOWN for nRF52 132 SDK 11

[RichieJH]

I see it is advised not to just stop a timer, but to also shut it down for certain of the nRF52s. What call is necessary to achieve this since I understand it is deprecated in SDK 11 which is presumably the reason I cannot seem to find a reference to it in v11?

Also after SHUTDOWN does it need to be created again or can it simply be restarted if required?

Where do you see that it is recommended to shut it down? Also, remember that the app_timer does not use a TIMER peripheral instance, but a RTC instance (which uses the 32 kHz clock). Most practical applications always have a RTC timer active at all times (for example the SoftDevice does with RTC0).

This is where I saw it devzone.nordicsemi.com/.../.

That is only valid for the TIMER peripheral, and has no relevance for the app_timer. The app_timer does not use a TIMER, but rather the RTC.

Excellent, thanks.
