https://devzone.nordicsemi.com/f/nordic-q-a/5419/setup-nrf8001Hi, I am trying to setup the nrf8001 by sending the setup commands from my microcontroller. After I send the complete setup packet (21 commands) I receive, as expected, the ACI_TRANSACTION_COMPLETE command (0x02). At this point I am not sure what shoulden-USTelligent Community 13Sat, 26 Sep 2015 17:43:48 GMThttps://devzone.nordicsemi.com/thread/18906?ContentTypeID=1Sat, 26 Sep 2015 17:43:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b68784e8-2bfc-43a6-af16-13e008ceb782David Edwin<p>This looks like a clock source issue. Ideally after the Setup is complete with the Status for the Command Response for the Setup Command coming in as ACI_TRANSACTION_COMPLETE , the Device Started Event (Mode = Standby) will arrive. However if you do not get the Device Started Event (mode = Standby) , it is likely that the 32KHz clock source is not set correctly and the nRF8001 is not able to startup. Set the 32KHz clock source in the nRFgo Studio -&gt; nRF8001 Configuration -&gt; Hardware Settings -&gt; 32 KHz source to <strong>internal RC oscillator</strong>. Let me know how it goes (my apologies for the delay)</p><div style="clear:both;"></div>
