DTM and clock source

DTM and clock sourcehttps://devzone.nordicsemi.com/f/nordic-q-a/16605/dtm-and-clock-sourceI made a product with nrf51822AC(based on SDK6.1&softdevice7.3), now we want to do BQB testing and I am working on our board's DTM code. I have tried example "\Nordic\nrf51822\Board\nrf6310\s110\ble_dtm" and changed pin configuration base on my boarden-USTelligent Community 13Fri, 23 Sep 2016 12:29:30 GMTRE: DTM and clock sourcehttps://devzone.nordicsemi.com/thread/63525?ContentTypeID=1Fri, 23 Sep 2016 12:29:30 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8efdc139-d677-4526-b9ad-166d1a309c2fbjorn-spockeli<p>Hi Frank, I am afraid that I do not understand why you want to set the clock source to <code>NRF_CLOCK_LFCLKSRC_RC_250_PPM_8000MS_CALIBRATION</code> when you do have an external 32kHz crystal. Couldnt you just use the default clock source, i.e. <code>NRF_CLOCK_LFCLKSRC_XTAL_20_PPM</code>?</p><div style="clear:both;"></div>
