https://devzone.nordicsemi.com/f/nordic-q-a/55226/connect-on-first-advertisingHi, I&#39;ve got some questions about setting up a connection. I want to connect as fast as possible with a UUID filter. Is it possible to connect directly on the first advertising or does the softdevice always need to wait for a second one?

You find the device you want to connect to on the first&nbsp;advertising packet, call&nbsp;sd_ble_gap_connect(), and the connect will happen on the second one.</span></p><div style="clear:both;"></div>
