Bluetooth no work! why?

Hello everyone! I kindly ask you for my problem with bluetooth.

  1. the Bluetooth module is recognized via USB
  2. I attached a power supply just for logic
  3. when I want to move Hexy via bluetooth (USB disconnected) the moduo does not seem to be recognized.
  4. I open POMOCO2e I get this information "trying COM4
    Serial Exception: COM4, (<class ‘serial.serialutil.SerialTimeoutException’>, SerialTimeoutException (‘Write timeout’,), <traceback object at 0x02C796E8>)
    trying COM1
    Serial Exception: COM1, (<class ‘serial.serialutil.SerialException’>, SerialException (“could not open port ‘COM1’: WindowsError (2, ‘The specified file could not be found.’)”,), <Traceback object at 0x02C794B8 >)

What can I do? Can you help me? Thank you in advance!
