https://test-devzone.nordicsemi.com/f/nordic-q-a/86443/ble-app-beacon-advertisement-periodI am using &quot;ble_app_beacon&quot; code in nRF5_SDK_17.0.2 so that it beacons every 10 seconds. When I increase beaconing period (NON_CONNECTABLE_ADV_INTERVAL) above 10.24s, the code does not work and I get this in the Debug terminal: &lt;info&gt; app_timer: RTCen-USTelligent Community 13 Non-ProductionThu, 31 Mar 2022 11:35:02 GMThttps://test-devzone.nordicsemi.com/thread/361003?ContentTypeID=1Thu, 31 Mar 2022 11:35:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f5814b7a-79d9-436f-9c69-27f8f58716a2user7377<p>Hi,</p> <p>A advertising interval above 10.24s is not supported. If you need a longer period, then I suggest you stop an start advertising. For instance, configure advertising with a long interval and start it regularly with a repeated app_timer with an interval of what you want (say 100 s to pick a number). In addition to starting advertising, also start a single shot app_timer at the same time with a decent delay (to accomodate the random offset and some margin) - say 20 ms. In that timeout handler, stop advertising. That way you know that you only send a single packet (on all three advertising channels) every time you start advertising.</p> <p>Einar</p><div style="clear:both;"></div>
