Hello @Sanjay Kumar Jha ,

It works on simulator, but it doesn't work when I try to run the app on my iPhone, the Native Crash Reporting and Native stacktrace show that " /System/Library/PrivateFrameworks/TCC.framework/TCC : <redacted> ". This crash is related to protecting app access to user data.

As noted in Core Bluetooth | Apple Developer Documentation - Your app will crash if its Info.plist doesn’t include usage description keys for the types of data it needs to access. You could open the info.plist file , then add the NSBluetoothAlwaysUsageDescription key and NSBluetoothPeripheralUsageDescription key. NSBluetoothPeripheralUsageDescription is deprecate, you don't have to add it if the deployment target of your app is iOS 13 and later.

Privacy - Bluetooth Peripheral Usage Description - A message that tells the user why the app is requesting the ability to connect to Bluetooth peripherals.
Privacy - Bluetooth Always Usage Description - A message that tells the user why the app needs access to Bluetooth.

In addition, please try to delete the bin/obj folder, uninstall the app from your device and deploy again.
Best Regards,
Wenyan Zhang
