https://devzone.nordicsemi.com/f/nordic-q-a/22439/gzll-esb-clock-requirementsI&#39;m looking at using an nRF51822 in a Gazell or ESB application. I prefer not to have any softdevice loaded at all. What is the correct procedure to perform clock calibration in this scenario? Is it required? If not, is there any advantage gained whenen-USTelligent Community 13Wed, 31 May 2017 15:53:04 GMThttps://devzone.nordicsemi.com/thread/88245?ContentTypeID=1Wed, 31 May 2017 15:53:04 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6ab48e48-36f3-4da0-be42-02c188f87229Andrew Kohlsmith<p>This answers my question.

ESB or Gazell doesn&#39;t use LFCLK or RTC. There is no connection interval, no calibration needed.</p><div style="clear:both;"></div>
