nRF52810 wake up on RF signal reception

[PoojaK]

I want to optimize my receiver power by putting the controller in sleep mode, that is ;-

NRF_POWER->SYSTEMOFF = 1;

And want to wake up the controller only when it receives any data packet on the radio. I have already tried wake up on gpio pin and it works great. But now I need wake from rf signal .

Here I am referring to the Nordic proprietary rf and not BLE.

Please Help me OUT!!

Hi,

to be able to receive packets, radio should be in RX mode (consuming about 5 mA with DCDC enabled) - the whole system cannot be put in SYSTEMOFF.  You can put CPU to sleep with __WFE() or sd_app_evt_wait(), it will wake up upon reception of a valid packet if you enable an interrupt for CRCOK event.
