Whenever I try to start in "connected mode" the program just crashes

[cvjensen]

Hello ,

I have installed DDT4ALL using the fully packaged installer for windows.

I'm using an ELM327 BT device that should have the right PIC18F25K80 chip .. I opened it up and there's the right number on the chip but I still dont know if it's a chinese copy?

I have tested the OBD BT device using my phone and some android apps - seems to be working fine.

If I dont start a command prompt first I cannot manage to read the errors, so here's the output from the command prompt whenever I try to press the "connected mode" button:

C:\Users\Rikke\Desktop>.\ddt4all.lnk
Initilizing ELM with speed 115200...
Trying to open portCOM3 @ 115200

  File "C:\Program Files (x86)\ddt4all\elm.py", line 574, in _init_
    maxspeed = int(maxspeed)
ValueError: invalid literal for int() with base 10: ''

Notice I do it 2 times - thats because for some reason the BT device shows up on windows 2 times. When I connect to both of the BT OBDII devices I get 2 different COM-ports - thats a little strange isn't it ?

Found this online:

The reason you had ValueError is because int cannot convert an empty string to the integer.

But it clearly states that it's trying with speed 115200 which I'm guessing is default for BT?

maxspeed is a function of the Python 3 version. The Python 3 version still contains some bugs. I recommend using the Python 2 version.

I will try that one of the following days. It's just funny that the readme says that Python 3.8 is a dependency .

have you tried downloading DDT4ALL from this Russian site , choose 'all cars exe' - and try choose 34800 baud rate -

yes that is normal 2 ports with a BT Dongle

@AndyIreland seems to be working fine. It is just great , thanks!

hi @AndyIreland , you don't by any chance know how to calibrate an edc gearbox ? :)

[AndyIreland]

Hiya - no, i have only made adjustments on Clio4 (non transmission settings) and Zoe EV sorry. could it be in the ECM / injection ECU section or that may be just be for the engine parameters?
