Hi,

You have the DEVICEID registers in FICR(Factory information configuration registers). The 2 DEVICEID registers each contain a 64 bit unique device identifier.

If you want to read and print the DEVICEID in the FICR register, you can do it like this:

NRF_LOG_INFO("DEVICEID0: %08X\n", NRF_FICR->DEVICEID[0]);
NRF_LOG_INFO("DEVICEID1: %08X\n", NRF_FICR->DEVICEID[1]);
