Only works when debug is enabled? #167

Closed romwhite closed 4 years ago

romwhite commented 4 years ago

Not seeing this specific issue mentioned. I'm using a Windows 10 PC and a obdator Mini Bluetooth OBD2 Scanner ELM327 and coding in Python3. Also I've seen threads talking about knockoff ELM chips... but I don't see anyone stating what OBDII readers have real ones.

I can only seem to get things to work when I've uncommented out the diagnostics line at the top. 

import obd
import time

obd.logger.setLevel(obd.logging.DEBUG)

connection = obd.OBD("COM8", fast=False, baudrate=38400)

while True:
    command = obd.commands.SPEED
    print("\n")

    r = connection.query(command)
    print(r.value)
    time.sleep(5)

Are you using the master branch?

romwhite commented 4 years ago

I'm using the version installed with pip. Should I have installed it differently?

alistair23 commented 4 years ago

Can you try using the master branch? It has some fixes that might fix the issue for you.

romwhite commented 4 years ago

Yes, I'll give this a shot. I've also ordered a hard wired OBDII reader as well. I don't know that I trust this bluetooth one.

romwhite commented 4 years ago

Wanted to mention that this resolved the issue. Not sure why... the version number didn't change.

alistair23 commented 4 years ago

Great!
