Please check this and let me know if any other help required byte [] Talk2BTsocket(BluetoothSocket socket, byte [] cmd, Mutex _mx, int timeOut = 150) { var buf = new byte [0x20]; _mx.WaitOne(); try { using (var ost = socket.OutputStream) { var _ost = (ost as OutputStreamInvoker).BaseOutputStream; _ost.Write(cmd, 0, cmd.Length); } // needed because when skipped, it can cause no or invalid data on input stream Thread.Sleep(timeOut); using (var ist = socket.InputStream) { var _ist = (ist as InputStreamInvoker).BaseInputStream; var aa = 0; if ((aa = _ist.Available()) > 0) { var nn = _ist.Read(buf, 0, aa); System.Array.Resize( ref buf, nn); } } } catch (System.Exception ex) { DisplayAlert(ex.Message); } finally { _mx.ReleaseMutex(); // must be called here !!! } return buf; }
