https://devzone.nordicsemi.com/f/nordic-q-a/29075/advertising-as-two-peripherals-at-onceHi there, We&#39;re looking at doing something with beacons so that we can make use of the way iOS handles scans for them in the background differently to other peripherals. Beacons are generally not connectable - they just advertise and the central scansen-USTelligent Community 13Sun, 18 Jun 2017 21:13:50 GMThttps://devzone.nordicsemi.com/thread/115299?ContentTypeID=1Sun, 18 Jun 2017 21:13:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ef3286c7-5a95-4cc7-bdcb-9572960be837endnode<p>Hi Eliot,</p> <p>Indeed you can be switching between two (or even more) advertising (and scan response) packets, radio_notification API is the best (unless you have some connection in the parallel which makes it little bit harder). The only problem is when you want to also change things like connectable/not connectable, whitelist, channel map etc., that is not well supported by Nordic Soft Device GAP API. See more examples <a href="https://devzone.nordicsemi.com/question/56603/nrf-master-control-panel-for-android-crashes-when-displaying-details-of-fast-advertising-peripheral/">here</a> and <a href="https://devzone.nordicsemi.com/question/101172/combined-ibeacon-advertising-and-standard-advertising/">here</a> and elsewhere on this forum (and I can tell you that iOS devices love it, GAP Peripherals being iBeacon and at the same time something else, you can be switching adv. address to appear as completely independent devices or not, beside small confusion in some applications BLE stacks in mobiles seems to be completely OK with both variants and iOS devices especially react on iBeacon broadcasting in situations when nothing else would wake them up).</p><div style="clear:both;"></div>
