Hi

    uint8_t mac[6];
    mac[0] = (((NRF_FICR->DEVICEADDR1) >>  8) & 0xFF) | 0xC0;
    mac[1] = (((NRF_FICR->DEVICEADDR1)      ) & 0xFF);
    mac[2] = (((NRF_FICR->DEVICEADDR0) >> 24) & 0xFF);
    mac[3] = (((NRF_FICR->DEVICEADDR0) >> 16) & 0xFF);
    mac[4] = (((NRF_FICR->DEVICEADDR0) >>  8) & 0xFF);
    mac[5] = (((NRF_FICR->DEVICEADDR0)      ) & 0xFF);

The set_bt_addr() function did not work for you? Did you get any error codes?

Hi , I tried this in the broadcasting sample and iBeacon sample but it did not work but now in a separate custom project it works , thank you .

what might be the reasons for it not working in the samples?
