https://devzone.nordicsemi.com/f/nordic-q-a/40606/fcc-certification-of-nrf51822-btleWe are going to FCC lab shortly to certify nRF51822 BTLE. We have done this before on previous products and passed with the same radio block. Unfortunately our compliance engineer and firmware engineer are no longer here, and I am not a firmware engineeren-USTelligent Community 13Mon, 19 Nov 2018 10:18:15 GMThttps://devzone.nordicsemi.com/thread/157907?ContentTypeID=1Mon, 19 Nov 2018 10:18:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e1edc5b8-a0bf-47e6-9e19-c112ae1d350bAndreas<p>Hi,</p> <p>&nbsp;</p> <p>You do not need the S110, only the radio test example hex, try only flashing this. This also might use different UART pins than usual, by default P0.06 and P0.08, if you use other pins you either have to connect to these, or change it in the FW and rebuild the code.</p> <p>&nbsp;</p> <p>Best regards,</p> <p>Andreas</p><div style="clear:both;"></div>
