I want to set the device name by combining &quot;XXXX&quot; and the lower 3byte of MAC Address. &quot;XXXX&quot; is used to recognize it as a company product, and MAC Address means the unique ID of the device.

The device Addr is generated randomly (it&#39;s generated in production and it doesn&#39;t change)</p> <p>You can set the device name to anything you want. It doesn&#39;t have to match with the MAC address. Change the device name using:&nbsp;sd_ble_gap_device_name_set()</p> <p>In addition, you can change the device Bluetooth address ( i assume it&#39;s the MAC address you are asking here).&nbsp;You can do that using&nbsp;this function&nbsp;sd_ble_gap_addr_set()&nbsp;</p> <p></p><div style="clear:both;"></div>
