Hi,
First, I would like to thank you for your work. I really like it and i'm trying to set it up in my car.
Even though i have an USB 327ELM it doesn't show much information of my car (Toyota Yaris 2003 D-4D)
It shows me a warning like "it may be fake adaptator" but it is strange because it is USB and i still can see rpm for example or km/h.
And i am using raspberry 3 desktop version.

Hello,
I am not a developer.
I am looking for a project (read OBD information in USB or WIFI) as yours to use it in my car on a Pi Zero W.
This one must manage MotionEye as well as RaspAp.
I wish a display without used GUI (a bit like "htop") for limited resources and that it is readable by a human (no hex).
Is this possible from your project?
Thank you for your reply.

My vehicle doesn't have canbus! How do i read fault codes from the K-Line? Can you point me on a direction?

I tried to add Honda and Ford car PID in data folder and configuration. I had no success, Please can explain how i can add them

First and foremost, absolutely love this project! I am able to successfully connect to my ODBII bluetooth adapter.

When I initiate your software, it loads and states that is connecting to the CAN BUS; however, it never connects. When i close the software, there are the following errors in the terminal:

"invalid literal for int() with base 16: 'CH' "

I'm not that great with Python otherwise I'd inspect the code myself. Is this a quick fix item?

Hello, when I try to launch « python PiOBDII.py » :
pi@LaCaseMove:~/PiOBDII $ python PiOBDII.py Traceback (most recent call last): File "PiOBDII.py", line 43, in <module> import ELM327 File "/home/pi/PiOBDII/ELM327.py", line 736 SyntaxError: Non-ASCII character '\xe2' in file /home/pi/PiOBDII/ELM327.py on line 736, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

I have cloned the code from GitHub and also installed all the required packages to run the program PiOBDII but still every time I try to run the program it gives me this error:

Please help me with this as soon as you can.

I've done the computations and am displaying "corrected" US standard Speed, RPM, Temp etc, but am having issue with manipulating Text display, to reflect the change. eg 45 MPH displays as 45 km/H and Coolant Temp displays 120 C rather than 120 F ... Can you push me in the right direction please.
Also, would like to spin off changes only for these conversions, and additional PID's additions if you wouldn't mind.
Coolant Temp -- Result = ((int(Response, 16) - 40)*1.8) + 32
Speed -- Result = int(Response[:2], 16)/1.60934

this is my ELM327.py code

...

THANKS A LOT !!!

I can not connect to my car, the screen just shows
FAILED TO INITIALIZE ELM327 DEVICE.
FAILED TO CONNECT TO ELM327 DEVICE.
my car is Ford Everest 2010 which used CAN (11/500kb)
and I am using Raspberry Pi 3 which already integrated Bluetooth inside so i don't need to use a USB Bluetooth dongle. So i think the serial port that i am using to connect Bluetooth is rfcomm, not USB port.
what do I need to do to make it works, I am not a coder? Please help me !

Is there anyone that help me with this project??!! I"M DESPERATE

Hello,

First, thank you for the amazing work ! I was really new over the OBD-II standard and I could have ramp-up on this thanks to the script.

I do not believe I found a bug but this is maybe kind of future improvements. For example, my car is a Renault Clio IV from 2016 and when I am requesting for the "0101" or "0100" the ELM gives back 12 bytes of data (if I do not count the \n ) which can be this :

>0100
41 00 BE 3E A8 13
41 00 88 18 00 11

>0101
41 01 00 07 A1 00
41 01 00 04 00 00

And in your script you consider first 2 bytes as the prune data, and the next 4 bytes are used for interpretation which means the second word I got back is not processed.
After some researches, it figures that several ECU may respond to any OBD service. And after turning on the hidden frame headers with the AT H1 command, it seems that the first word is coming from the "7E8" guy (the Engine Control Unit) and the other from the "7E9" guy (the Transmission Control Unit) and I am not sure if Engine is always answering the first or not.

For instance I had some DTC from the TCU and I had to make small fixes to mask the headers when doing the AT commands because in the actual script snapshot, it did not show up.

I don't know what could be the best way to improve it and if you already heard of that but at least you are now aware.

(In terms of hardware I have a OBDII-2-UART from Sparkfun with a STN1110 chip (elm v1.4b) which is not categorized as a "Fake ELM device" by your last commit :) )

Thanks for this work! I'm planning to run your code on a Windows PC through an ELM USB cable and specifically have an issue with the passenger side airbag (I believe that's code B1937) on my Ford F150. Any thoughts on Python calls that might ping B1937? Diagnosing or resetting? Thanks again!

In pyOBDII.py lines 530 and on, the filename assumes that the vehicle VIN can be retrieved via the 0902 command.
In my case (1996 Saab 900) this command returns N/A
So the filename is constructed as SAVE/date..N/A.pdf which cannot be written as the second / is interpreted as a directory separator.
In my case I just commented out line 533 and added
FileName += '.pdf'

However this is not the proper solution
