title: Receiving data from arduino with bluettoth HC-05 module to python - wierd numbers recived and conversion
body: <p>I asked this question before to know how to convert the byes to ints here: and now I have a different situation.</p>
  <p><a href="https://stackoverflow.com/questions/72905045/send-data-to-from-arduino-to-raspberry-using-bluetooth-hc-05-and-python-byte-c">Send data to from Arduino to Raspberry using bluetooth hc-05 and python - Byte conversion</a></p>
  <p>The HC-05 is connected to pin 1 and 2 in arduino TX to RX and RX to TX (PI, Arduino).</p>
  <p>The solution kindly sent was the function int.frombytes. That worked ok. But the only numbers I could see were 255, 254, 255, 10, 255, 254.</p>
  <p>I tried unplugging the usb cable form the pc and powering the arduino from a battery and same thing happened.</p>
  <p>Now, I modified the sketch from arduino to send only the number 2 and in raspi python I still receive 255, 254, 255, 10, 254, 255.</p>
  <p>Has anyone had the same problem?</p>
