CAF wake up from sleep with timer.

[Tiit]

Hi

I would like to use power management module with CAF. I got it somehow working and the device is going to poweroff  or standby mode and wakes up, if i push some button, but I want to build a battery powered sensor device, with longest battery run as possible (sensor manager gets periodically the samples from sensor and the device goes standby).

As I understood CAF supports wake up from physical touch (GPIO or NFC), but can I use timer for that or is everything in idle, if board is on standby?

Hi 

As long as you use the normal standby modes, and not poweroff, you can have timers running in the background. 

Then it is no problem to wake up either on a button press from the CAF module, or once a Zephyr timer or RTC timer expires.
