startScanning method
Starts scanning for Empatica devices once the EmpaStatus.ready is thrown.
Once a device is found, the statusEventSink will throw a DiscoverDevice event. This event contains the device's serial number, along with a label with the MAC address and the RSSI connection strength.
Implementation
Future<void> startScanning() async {
await _methodChannel.invokeMethod('startScanning');
}
