https://devzone.nordicsemi.com/f/nordic-q-a/505/device-uuidDear Nordic, I know each sample has unique device address and stored in NRF_FICR-&gt;DEVICEADDR[0] and NRF_FICR-&gt;DEVICEADDR[1], and I think it has unique device UUID too. Where dose the UUID come from? As shown in the attachment. Thanks, Elcaen-USTelligent Community 13Tue, 24 Sep 2013 04:07:43 GMThttps://devzone.nordicsemi.com/thread/2639?ContentTypeID=1Tue, 24 Sep 2013 04:07:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a223009e-057a-4395-a5c4-21da67149b2eElca<p>Thank you for your reply.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/2638?ContentTypeID=1Mon, 23 Sep 2013 07:37:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d94024fd-dc4a-4e6a-b233-44218450a2e6Carles<p>Hi there,</p> <p>This UUID is generated and assigned by iOS, not by the SoftDevice. Assigning a UUID to a device is a concept particular to iOS, not to the Bluetooth spec.</p> <p>Regards,</p> <p>Carles</p><div style="clear:both;"></div>
