https://devzone.nordicsemi.com/f/nordic-q-a/6906/srrc-certificationMy product have to pass SRRC certification. The certification lab need 3 prototype. Their bt RF frequency must work at 2402MHz, 2441MHz and 2480MHz separately. How can I fix the RF frequency then?en-USTelligent Community 13Sun, 19 Jul 2015 11:40:56 GMThttps://devzone.nordicsemi.com/thread/24346?ContentTypeID=1Sun, 19 Jul 2015 11:40:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ffafdd34-6afe-45a7-8592-84afae341f10mansfield<p>Thanks! I use direct test function of nrf go studio to fix this problem finally.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/24344?ContentTypeID=1Fri, 17 Jul 2015 09:04:17 GMT137ad170-7792-4731-bb38-c0d22fbe4515:94b926e0-19bc-493c-95a7-c543eff02623Susheel Nuguru<p>mansfield, please update/accept/comment on this case.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/24345?ContentTypeID=1Wed, 06 May 2015 08:41:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5d4855e8-cfeb-40ee-a4d5-0759d47a3b51Susheel Nuguru<p>You can change the channel map but each channel map is 2 MHz apart. you cannot get 2441MHz. This I guess is a hardware limitation.</p><div style="clear:both;"></div>
