https://devzone.nordicsemi.com/f/nordic-q-a/9273/how-to-change-radio-frequency-without-disabling-the-radioHi. I am using the nRF52 Preview Dev. Kit to send data over multiple channels by setting the NRF_RADIO-&gt;FREQUENCY register to the desired frequency value. To make it work I have to disable the radio after TX done set the new frequency and enable theen-USTelligent Community 13Fri, 19 Aug 2016 07:08:26 GMThttps://devzone.nordicsemi.com/thread/34223?ContentTypeID=1Fri, 19 Aug 2016 07:08:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9b91276c-c796-436b-b39d-4ef93afe83bcSusheel Nuguru<p>Hi CurtisHx, sorry for very late response, yes this is a hardware limitation set by designers to have a predictable radio performance.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/34222?ContentTypeID=1Tue, 05 Jul 2016 17:45:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9b3f5b82-591b-4fbf-8160-e6f747e73bf7CurtisHx<p>I just ran into this same problem as well. Is this a hardware limitation? Because the idea of being able to advertise on all 3 BLE channels in under 50us is <em>really</em> appealing for ultra-low power devices.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/34221?ContentTypeID=1Mon, 21 Sep 2015 11:34:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:543e6d50-d5a5-436f-a41b-55f0897ae2ecSusheel Nuguru<p>You cannot change radio frequency without disabling radio. it seems that this is not documented well but it needs RADIO not to be active for this register settings to take effect.</p><div style="clear:both;"></div>
