Any idea why nothing happens after "Send command:atz"?

Pyobd seems to be quite picky about delays between command and reply. One thing that you could try is to modify delay after atz command.

If you know how to edit pyobd python files, you can try to increase delay after sending "atz" command in /home/opt/pyobd/obd_io.py.
You can try different values in time.sleep() to see if that helps.

Code:

while 1: #until error is returned try to connect
  try:
    self.send_command("atz")   # initialize
    time.sleep(0.2) # try here 0.5 for example
