How can I get the mac adress of my chip from main code?

[gootoomoon]

Can not find the mac adress related information from the PS or RM doc. Need your help!

If you want to read out the Bluetooth address used by the chip, you can use the function sd_ble_gap_address_get(), defined in ble_gap.h.

Edit: Not tx_address, just address.

How about using:

uint64_t deviceId = ((uint64_t)NRF_FICR->DEVICEID[1] << 32) | ((uint64_t)NRF_FICR->DEVICEID[0]);

Is it deprecated, or is it some other address? In my all applications I am using this method, and the address is different than address returned by sd_ble_gap_address_get()

Because sd_ble_gap_address_get() read from NRF_FICR->DEVICEADDR, if you change to

uint64_t deviceId = ((uint64_t)NRF_FICR->DEVICEADDR[1] << 32) | 0xC00000000000 | ((uint64_t)NRF_FICR->DEVICEADDR[0]);

You will get the same data as sd_ble_gap_address_get().
