Since WatchOS 8.0.1 CoreBluetooth drops an active connection if the App goes to background (or back to foreground). This can be reproduced easily with this sample code: Interacting with Bluetooth Peripherals During Background App Refresh If you run the app on the Apple Watch and turn your wrist, an active connection is terminated. In the output window you can read: 2021-10-20 20:22:41.210839+0200 BARBluetooth WatchKit Extension[382:94603] [BluetoothReceiver] disconnected from Sender. The same is the case with my other Watch Apps, that are connecting to BLE devices. As far as I remember, with WatchOS 8.0 everything was fine. Since this occurs even on WWDC21 sample code this must be a bug. Is there a way to fix it for myself, or do I have to wait until it gets fixed by Apple?

Is it possible to integrate a simple custom Bluetooth gaming controller such as a Arduino built joystick with my mini watchOS game I’m creating?

We use External accessories framework for Bluetooth communication with medical equipment.  Mobile App was in Foreground but iOS (15.5 beta) triggered AppDelegage callback applicationDidEnterBackground event, when external accessories framework establish the connection to or disconnect from the medical equipment.  iOS should trigger this event only when the user moves application to background. We encounter this issue in iOS 15.5 Beta version, which seems to be iOS 15.5 beta issue.

My Bluetooth headphones are cracking and popping. This topic is on a lot of forums but I haven't found any fixes. Some of them are quite old. There is a really long run on this forum in fact years however there's not a fix for me. I did have success with reset the Bluetooth module this morning and it cleared up the distracting noises. I/m back on my computer this ever working in Logic Pro X and it's back. ANY HELP would be greatly appreciated. Thank You in advance. I have a late 2105 iMac Big Sur 11.4 Graphics: ADM Radeon R9 M390 2 GB 32 GB RAM
