I&#39;m developing a peripheral device using nrf52840 to communicate with our android developed app. I&#39;m testing the latency between connections of device. the configurations are below.

Normally you first scan, wait for advertisement and then choose to connect by using the second api. But there is nothing preventing you to use the connect api directly if you know which peer to connect.</p> <p>Kenneth</p><div style="clear:both;"></div>
