Hi,
We are developing an application with a custom nrf5340 board in which beacons are sent periodically every 100ms. We have been analyzing power consumption with a Power Profiler Kit and we have been able to send the device, whenever necessary, to System Off mode, which obviously stops the advertising and therefore drastically reduces consumption.

After reading this post (https://devzone.nordicsemi.com/f/nordic-q-a/15062/power-optimizing-nrf-beacon) we got a bit confused and wonder if it is even possible to go into System Off mode and get those 17mA every time the device is not advertising, by means of waking up with a timer or any other option, considering we want it to be automatic and don't rely on any GPIO, NFC sense...
Thank you so much!
Cheers!
