nRF52 Example wake_on_nfc

[Arepa]

Hi all,

I am testing this example and I have some question is possible using theR same NFC to turn off the nRF52? I cant see where the NFC event is handle

Can some one give any suggestion?

Hi,

This should be possible, but not in the same way that the wake_on_nfc example works. This example configures the device to wake on NFC field by setting NRF_NFCT->TASKS_SENSE = 1;. This will trigger a reset on wakeup from System off mode.

I have altered the nfc_text_record example to put the device into system off mode using NFC. The device is at the same time configured to wake on NFC field again. Note that the device is put in system off mode on the NFC_T2T_EVENT_FIELD_OFF event.

Hi Jørgen,

I am combining the wake_on_nfc and nfc_text_record example that you used. one for make the nRF52 ready for wake up and the other for messages and turn off the system.

Thanks a lot for you help :)

cheers
