I iCAB Well-Known Member Licensed User Longtime User Jul 23, 2021 #1 Hi Guys, We are working on an app that communicates with a Bluetooth device. As part of the requirements the app should be able to continue to do so in background mode, but not when the phone is locked. So we need a way/event to detect the lock/unlock actions. I found this article, but not sure how to use it with B4I and if it is the right way of doing it or not: https://stackoverflow.com/questions...to-check-if-the-ios-device-is-locked-unlocked Thanks, iCAB Last edited: Jul 23, 2021

We are using an SDK that needs to continuously scan for Bluetooth devices. If a device of interest, is found, it connects to the device, exchanges some information, and then disconnect.

Are you using one of the standard background modes? Have you seen this answer: https://stackoverflow.com/a/43624669/971547 ? Upvote 0
