nRF52832 / changing clock source dynamically in the FWhttps://devzone.nordicsemi.com/f/nordic-q-a/36129/nrf52832-changing-clock-source-dynamically-in-the-fwHello, We&#39;ve a Custom board based on nRF52832, it works fine in beacon mode using the Synth Clock (else it doesn&#39;t work): // &lt;o&gt; CLOCK_CONFIG_LF_SRC - LF Clock Source // &lt;0=&gt; RC // &lt;1=&gt; XTAL // &lt;2=&gt; Synth #ifndef CLOCK_CONFIG_LF_SRC #define CLOCK_CONFIG_LF_SRCen-USTelligent Community 13Fri, 06 Jul 2018 07:24:43 GMTRE: nRF52832 / changing clock source dynamically in the FWhttps://devzone.nordicsemi.com/thread/139188?ContentTypeID=1Fri, 06 Jul 2018 07:24:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d9715739-c10b-45f8-acbe-0469e44f6f79ovrebekk<p>Hi John</p> <p>To answer your question, yes, you can change the LF clock source dynamically if you like. That said it shouldn&#39;t be necessary, will complicate your firmware and increase the overall current consumption.&nbsp;</p> <p>What happens if you try to use the RC&nbsp;source all the time?</p> <p>Have you made sure to request external HF clock before enabling the radio?</p> <p>Are you using a SoftDevice for the beaconing, or are you using custom code?</p> <p>Best regards<br />Torbjørn</p> <p>&nbsp;</p><div style="clear:both;"></div>
