https://devzone.nordicsemi.com/f/nordic-q-a/8873/do-i-need-to-start-advertising-to-enable-uartOn 51822 : tt seems to me that I need to call sd_ble_gap_adv_start before I can use uart... Do I also need dtm_set_timer etc to start uart ?

This is how I realized I needed to call <code>sd_ble_gap_adv_start</code></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/32632?ContentTypeID=1Mon, 24 Aug 2015 13:06:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f85515d8-2d6a-4edc-a1db-96ed9dbd4f65Susheel Nuguru<p>please give more context. You do not need to start advertising for UART to start. These two are not related. Same goes with dtm function. Which application are you trying to run?</p><div style="clear:both;"></div>
