 my dev board is nrf5340dk. 
 I took a sample that under zephyr handsfree_ag. In build configuration I added nrf5340dk/cpuapp. I have built and flashed my dev kit. I checked serial and saw that message; 
 &amp;quot;Bluetooth init failed (err -11)&amp;quot;.

&lt;p&gt;The&amp;nbsp;&lt;a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/zephyr/samples/bluetooth/classic/handsfree_ag/README.html"&gt;Hands-free Audio Gateway (AG) sample&lt;/a&gt;, which is part of Zephyr, is for Bluetooth BR/EDR (Classic) only, not for BLE. Our SoCs and solutions only supoprt BLE. Therefore, regardless of any other issues (which may or may not be resolved), that sample cannot be run on any Nordic Semiconductor devices.&lt;/p&gt;

&lt;p&gt;It may be the order of the includes or the Sequence of the Main setup,&lt;/p&gt;
&lt;p&gt;Also I had to RECOVER the board before I could get a good flashing. You may have some corruption also. Do that and try again.&lt;/p&gt;
&lt;p&gt;HTH&lt;/p&gt;
&lt;p&gt;GL :-) PJ :v:&lt;br /&gt;&lt;br /&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
