BT on/off not working in iOS 14

[NgNivida]

With new iOS 14, the Bluetooth enabled/disable has stopped working. Anybody looking into this issue?

Same here, when Turn ON bluetooth with iOS 14, can someone help please?
Debugging with Xcode, it shows:

Insufficient entitlements to invoke BTLocalDeviceSetModulePower: 13
[BluetoothManager] failed to set power on with error 13

But the app built and run fine with iOS 13.

Any updates on this? Also encountered this problem in iOS 14.

Upgraded to iOS14.6 and new Xcode, this issue is not observed.
But hit by the following issue:

[MobileBluetoothFramework] MBFXPC LOG Failed to attach to the Bluetooth daemon as the XPC connection is invalid
[BluetoothManager] Session attach called back with BT_SESSION_ATTACHED (1)
[MobileBluetoothFramework] MBFXPC LOG Failed to attach to the Bluetooth daemon as the XPC connection is invalid

Think this is related to https://developer.limneos.net/?ios=14.4&framework=BluetoothManager.framework&header=RemoteDeviceManager.h

and similar to #28
which is Notification issue?

Can anyone help please?

Spent a few days trying different things, and still not getting anywhere.
This issue was likely due to the change introduced to CoreBluetooth during iOS 13, then iOS 14 private API's:
https://developer.apple.com/videos/play/wwdc2019/901

In general, it looks like the Private BluetoothManager failed to establish XPC connection with the Bluetooth daemon when instantiate the SharedInstance. Many suggested issues with the Info.plist, and object went out of scope, which didn't help.

I assume iOS 14 still uses Bluetooth's Notifications, as there isn't an article to say otherwise; which then suggests that we need to establish the XPC connection with the Bluetooth daemon, in order to get the notifications to work. I had explored "BluetoothBridge", "BTServicesClient" etc. and still the same.

Hopefully someone with better understanding can revive this project.
