https://devzone.nordicsemi.com/f/nordic-q-a/27217/auto-unlock-with-iosHi, i am actually working on a smart lock and i want to implement an Automatic Unlock. This functionnality can be really useful, because the door unlock even if your smartphone is in your pocket. On my smart lock, using the NRF52832 (S132), i haveen-USTelligent Community 13Wed, 08 Nov 2017 14:15:04 GMThttps://devzone.nordicsemi.com/thread/107350?ContentTypeID=1Wed, 08 Nov 2017 14:15:04 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2c569e1c-47af-41c5-a699-9389bcf72780Hung Bui<p>I&#39;m no iOS expert, but there was some discussion <a href="https://devzone.nordicsemi.com/question/138096/background-ble-operations-with-ios/">here</a> and some information <a href="https://developer.apple.com/library/content/documentation/NetworkingInternetWeb/Conceptual/CoreBluetooth_concepts/CoreBluetoothBackgroundProcessingForIOSApps/PerformingTasksWhileYourAppIsInTheBackground.html">here</a>.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/107349?ContentTypeID=1Tue, 07 Nov 2017 10:05:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f939ddac-459c-4e3a-9127-dd48b9b61b7aendnode<p>Oh sure there are some ways. As you probably know there are plenty of such BLE locks in the field already so you can simply go and learn from these companies (who invested 5+ years of know how into it;). Yes, advertising iBeacon and use it as kind of geo-fancing helps. Some companies use reverse GAP&amp;GATT roles or dual (so each device can use whatever is more convenient for given app and operating system). In addition there are other tricks how to keep iOS app alive or to be more precise how to restart it on various events if system kills it in the meantime. But I&#39;m afraid this is not the best forum to discuss as it has very little to do with BLE itself but it&#39;s more about iOS development. There are better forums full of &quot;experts&quot; on that matter...</p><div style="clear:both;"></div>
