https://devzone.nordicsemi.com/f/nordic-q-a/28253/thread-reading-peer_address-fieldsHey, For my project I am working on I am using openThread to multicast when a Thingy52 connects to a nRF52840. The nRF52840 (central) connects with a Thingy52 (peripheral) using BLE. I store the BLE MAC address and multicast this, so far so good.en-USTelligent Community 13Wed, 13 Dec 2017 09:15:43 GMThttps://devzone.nordicsemi.com/thread/111598?ContentTypeID=1Wed, 13 Dec 2017 09:15:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f8655671-123f-4982-a10f-579d66c52156ToasTer86<p>Thanks Hung, I got the address printing fixed with your tips.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/111597?ContentTypeID=1Tue, 12 Dec 2017 14:26:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0f932a08-08a3-46d0-90a7-b9e692f09283Hung Bui<p>The values are correct. It&#39;s only about the endianness and the number of digits you print with printf.
