https://devzone.nordicsemi.com/f/nordic-q-a/96652/read-board-mac-address-in-zephyrHello ! nrf5340 have unique chip number what as usually used for compose BT MAC address for example. I can read it by nrfjprog $ nrfjprog --memrd 0x01FF02A4 --n 8 --coprocessor CP_NETWORK 0x01FF02A4: F662CF1F 65F529D7 |..b..).e| Do you haveen-USTelligent Community 13Fri, 17 Feb 2023 12:45:47 GMThttps://devzone.nordicsemi.com/thread/410640?ContentTypeID=1Fri, 17 Feb 2023 12:45:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8c170e51-41d5-45a4-a663-131a2d0ff92fdejans<p>Hi Eugene,<br /><br />You should be able to read the&nbsp;<a href="https://infocenter.nordicsemi.com/index.jsp?topic=%2Fps_nrf5340%2Fchapters%2Fficr.network%2Fdoc%2Fficr.network.html&amp;cp=4_0_0_5_3_0&amp;anchor=register.DEVICEADDR">FICR DEVICEADDR</a>&nbsp;register directly from the network core as it is accessible only from there.<br /><br />Best regards,<br />Dejan</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/410462?ContentTypeID=1Thu, 16 Feb 2023 18:15:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ac4c2866-8d99-4ee6-9a21-7ec56d8700c7Hiihtaja<p>Hi !</p> <p>In my case I have own radio and can&#39;t include those BLE frameworks.</p> <p>I can see some drivers read&nbsp;NRF_FICR-&gt;DEVICEADDR[0/1] directly.</p> <p>But I can&#39;t do it , no idea what headers to include in NET_DEVICE driver for be able to support nRF52840 and nRF5340 devices.</p> <p>May be some low level nordic API what can read and compose 8 byte link address ?</p> <p>Regards,</p> <p>Eugene</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/409910?ContentTypeID=1Tue, 14 Feb 2023 15:25:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c927bc51-7f0b-4fae-a132-fef264f95e61dejans<p>Hi,<br /><br />This&nbsp;<a href="https://devzone.nordicsemi.com/f/nordic-q-a/84539/zephyr-nrf52840---how-to-get-the-mac-address-of-ble">discussion</a>&nbsp;might be helpful if you are looking for BLE MAC address.<br /><br />Best regards,<br />Dejan</p><div style="clear:both;"></div>
