https://devzone.nordicsemi.com/f/nordic-q-a/3479/peripheral---auto-connect-to-androidHello, I am currently starting with the hole ble topic. This forum helps me a lot in the last weeks to understand ble. I am using S110 to provide a peripheral device. It works without any problems. As client I build an android application.

So Ziran suggestion could be the solution you are looking for. You can not adjust scanning window or scanning interval on Android or IOS device but you can adjust the scanning timeout. So you can program your app to start the scanning periodically and then have a relatively short scanning timeout.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/12595?ContentTypeID=1Thu, 14 Aug 2014 09:57:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e0bce32b-37e1-4286-8658-60f4031699b8Ziran<p>My Colleague made a loop of scanning and not scanning so whenever your device send advertisement data and your smartphone is scanning it will connect.Not the best choice but it works xD</p><div style="clear:both;"></div>
