Hi @pauldemarco

List<BluetoothDevice> devices = await FlutterBlue.instance.connectedDevices;
List<BluetoothService> services= await devices[0].discoverServices();
print('$services');

Android error : java.lang.IllegalArgumentException: Unsupported value: java.lang.Exception: no instance of BluetoothGatt, have you connected first?

iOS error: not print log and services

TKS

@LiangLuDev yes the device has to be connected before you can call dicoverServices. The new version will throw an exception when you don't. Can this be closed?

@ride4sun current connected. iOS : Although the settings show that it is connected, it still needs to be connected in the app

Can describe that behavior a bit better? - Possibly with some code.
