https://devzone.nordicsemi.com/f/nordic-q-a/37339/does-a-peripheral-automatically-go-to-sleep-between-broadcastsHello, We are using in nrf51822 in a product. I do not understand whether by definition and, thus, always, before connecting, whether a peripheral goes to sleep between broadcasts or whether this is hardware or software configurable.

Then you will go to sleep as long as there are no events/interrupts running, and as long as you don&#39;t run any other code in the main loop.&nbsp;</p> <p>Best regards<br />Torbjørn</p><div style="clear:both;"></div>
