Thread: How do I set up obdgui?

My first feeling is that you have the wrong serial dev for your OBDII device. Are you using bluetooth? USB? Serial? Which /dev entry are you using? Which OS are you on? I support OSX, Linux, and probably others depending on how nicely someone asks.

Can you go to window->raw output and click the checkbox to capture output, *before* clicking "go"? You can leave that window open while you use the main UI. The stuff that I want to see should appear in the right hand pane. Can you paste that here?

It's also worth noting that while debugging and setting up, it may be easier to use the command-line. So long as gpsd is running fine for you, just while testing the only thing you need to do is "./obdgpslogger -t -s /dev/your-obd-device"

Oh... and what's your OBDII device? It's elm327 compatible, right?

I'm getting a lot of:
>BD reported NO DATA for cmd 10: NO DATA

update: when I started the obd from another program and then started obdgui I was able to read oil temp, rpms, and speed but not the other two gauges.

Grab the latest svn, see if that fixes your problem.

Sorry about the delay. It did show tps. I'm still not getting MAF.

To get it to work I have to start another obd program first. Then I start obdgpslogger. I had a similar problem with the obd stuff in the nghost project and I believe it tuned out the developer had to have a longer delay when communicating.

Ah, someone else recently had this problem, I'll push something into svn later to fix it. For now:

1) Edit src/logger/obdserial.c
2) Find the blindcmd() calls around lines 100-105
3) Add another one that looks like:
blindcmd(fd,"ATST50");
[alpha tango sierra tango five zero]

See if that fixes it.

You might also try running obdgpslogger with "-p" to get a list of what PIDs your car supports.

OBD reported nodata for cmd 00:

Sounds like it is still having problems initializing the device.

Try logging the serial comms, with --serial-log=serial.txt or similar

Try increasing the timeout again. Say, ATST70 ?

I added in an atz before all your commands and everything seems to be working as I would expect.

I'm now in the process of tweeking it to show the gauges I want (even though I haven't decided what i want yet ).

Cool.

FWIW, I've now added an ATZ at the start in svn. I've also added one in my closeserial function, so hopefully I'm leaving the device in a state so that other software won't exhibit these same problems, no matter what I do in future.
