BLE MAC address

[Starin1]

Dear Team,
Can we change MAC address of nRF 5340 pdk/dk development board or it is fixed?

Hi,

You can set the BT address using bt_id_create(). For instance, like this to set the address to DE:AD:BE:EF:BA:11:

	int err;
	bt_addr_le_t addr;

	err = bt_addr_le_from_str("DE:AD:BE:EF:BA:11", "random", &addr);
	if (err) {
		printk("Invalid BT address (err %d)\n", err);
	}

	err = bt_id_create(&addr, NULL);
	if (err < 0) {
		printk("Creating new ID failed (err %d)\n", err);
	}

Note that this must be done before enabling bluetooth.

Thanks,
BUT it is not working, i am using "C:\User\ncs\v1.4.2\nrf\samples\bluetooth\peripheral_uart\src" code to advertise MAC address.

Hi，Einar

Is there a way to update the mac address after enabling Bluetooth?

I have initialised it before bt_enable, but it shows the following error.
