libobd????
I guess that is something to do with CARMAN.
Am I correct, is there a way to correct it?
Cheers.

I am not really expert...so I guess I have to leave it and forget it.
I thought it was ELM problem, but as you pointed out, it was langauge problem.
I have re-installed the application again, and thought by doing that it will learn the language
no luck.
Just wondering how do others get connected and why did not they get the problem?
Can I ask any developer to help?
ortherwise, got to forget it.
Cheers.

OK, this is a bit weird, I've made a few changes to the ELM327 startup in carmand which appeared to get my car working again every other try but when I checked the report file my changes didn't appear to be actually there! I'll check what I've done but if you guys hadn't noticed it's Saturday night so I'm about to get ready to go out and this will have to wait.
@makkan00 my guess is that this is a problem with the way Carman communicates with the ELM327 so getting that bit right hopefully will fix these connection problems. If I get somewhere I'll send you my fixes somehow to test

Code:
if(obdchanelm_ssendcmd(chan, "ATSP0", 6)) { /* Set protocol to Automatic */
ret = OBDCHANERR_SETUP_ERROR;
goto error;
}
if(!strstr(pelm->buffer, "OK"))
LOG_WARNING("Unable to set ELM to use Automatic protocol");

I agree with you, its the way carman tries to communicate with ELM. And my connection to car through netbook and android phone confirms that it is either carman (or possible language as JLU reported).
As as I am not really expert in that language, so I should wait for you or Jlu to take a step ahead
Enjoy your weekend.

The third parameter of obdchanelm_ssendcmd is a timeout, so a suitable value might have to be tested.Code:if(obdchanelm_ssendcmd(chan, "ATSP0", 6)) { /* Set protocol to Automatic */ ret = OBDCHANERR_SETUP_ERROR; goto error; } if(!strstr(pelm->buffer, "OK")) LOG_WARNING("Unable to set ELM to use Automatic protocol");
Can you please tell me, which file in carman software or libobd's should be changed?
Where can I find that file, and how can I entre the commands you mentioned above?
As I am not expert like you, so I many need bit more guidance.
Cheers.

As I didn't have time to investigate what was actually happening, I assumed that either the device was dead or my car's battery (which was really dead) was somehow preventing the connection. I said I would retry after changing the battery, but I forgot. I think I'd better try again one of these days.
But now that you mention you have the same problem, I wonder if there was an update some time ago that broke something.
