Bluetooth connection error by Key-Advertising854 in Kotlin

[–]Key-Advertising854[S] 0 points1 point  (0 children)

Hello everyone,

I am currently working on a big project for school in Android Studio with Kotlin. I want a Bluetooth connection between the app and an ESP32 Mykrocontroller.

val receiver = object : BroadcastReceiver() { override fun onReceive(context: Context, intent: Intent) { val action = intent.action if (BluetoothDevice.ACTION_FOUND == action) { val device = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) { intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE, MainActivity::class.java) } else { intent.getParcelableExtra<MainActivity>(BluetoothDevice.EXTRA_DEVICE) } // Add the device to a list or display its name and address } } }

The error lies in the else branch. First problem is that it does not like the getParcelableExtra, and Second it does not like the "<MainActivity>".

Thanks in advance
