 I can able to get the DEVADDR0 and DEVADDR1. I am not able to make out How this EUI64 id is calculated using the DEVADDDR value. 
 I always get F4CE36 starting numbers in EUI64 id. Why it is happening. 
 Exmple: I got my

Great. I would like to go ahead with fa-ce-36 + 40 bits. &lt;/p&gt;
&lt;p&gt;For any time fa-ce-36 will not change until I use Nordic Semi radios.

&lt;p&gt;The IEEE EUI-64 address consist of two parts:&lt;/p&gt;
&lt;p&gt;- 24 bits of MA-L (MAC address block large), formely called OUI (Organizationally Unique Identifier).&lt;/p&gt;
&lt;p&gt;- 40-bits device unique identifier.&lt;/p&gt;
&lt;p&gt;By default, the device uses Nordic Semiconductor&amp;#39;s MA-L (fa-ce-36). You can modified it by overwriting &amp;#39;OPENTHREAD_CONFIG_STACK_VENDOR_OUI&amp;#39; define, located in &amp;#39;openthread-core-nrf52xxx-config.h&amp;quot; file, but this value must be publicly registered by the IEEE Registration Authority.&lt;/p&gt;
