RE: Two BLE nrf5340 devices with two different names appearing as one in nrf Connect iOS app w/name rotating

It was my mistake. I took this code from one of the DevAcademy lessons I think:

    bt_addr_le_t addr;
    err = bt_addr_le_from_str("FF:EE:DD:CC:BB:AA", "random", &addr);
	if (err) {
		LOG_ERR("Invalid BT address (err %d)", err);
        return err;
	} else {
        LOG_DBG("BT address set");
    }


    err = bt_id_create(&addr, NULL);
	if (err < 0) {
		LOG_ERR("Creating new ID failed (err %d)", err);
        return err;
	} else {
        LOG_DBG("New ID created with index %d", err);
    }

I just commented it out and was fine.

Hi,

Have you somehow ended up with both boards advertising using the same address?

A sniffer trace would reveal all details about what is happening over-the-air.
