Can't receive data via BLE on Android 14

[siroaleksi]

I have created Jetpack compose Android application which connects to a BLE device. BLE device updates its state and sends data to the app. Previously I have used Android 11 device and now I have updated my device to one that has Android 14.

I'm facing problem when trying to send data to app with Android 14. I'm using v2.9.0. On Android end, I receive characteristic changes like this:

    private val dataReceiver: BroadcastReceiver = object : BroadcastReceiver() {
        override fun onReceive(context: Context?, intent: Intent?) {
            val action = intent!!.action
            Log.i(tag, "This is the action $action")
            try {
                when (action) {
                    bluetoothManager.actionConnected -> {

                    }
                    bluetoothManager.actionDisconnected -> {

                    }
                    bluetoothManager.actionDataAvailable -> {

                    }
                    bluetoothManager.actionInfoAvailable -> {

                    }
                    bluetoothManager.actionError -> {
                       
                    }
                }
            } catch (e: Exception) {
                Log.e(tag, "onReceive ${e.stackTraceToString()}")
            }

When using exactly same code (excluding BLE permissions), with Android 11, I receive data normally and in the Log I get "This is the action ACTION_DATA_AVAILABLE" as expected. With Android 14 I get status updates e.g. "This is the action CONNECTED" and "This is the action DISCONNECTED" but for some reason it doesn't register "This is the action ACTION_DATA_AVAILABLE". When changing back to phone with Android 11 everything works as expected. I have also verified that code works with Android 12. Problems occurs now only with Android 14.

What might cause this? Are there some sort of security things that I need to take into account etc.?
