OBD data

oriebirj4 years ago

I bought the recommended freematics traccar edition device but so far I'm unable to get any OBD data.
Not sure what is achievable, but I was expecting to be able to get information about the different sensors as well as different metrics.
Any suggestions on how to get that data or even what is possible. cant find any documentation regarding that.
From freematics the support is hard, although I understand that in terms of software things are given "as it is".

Thanks in advance

Are you using correct firmware? Are you sure your vehicle is reporting the data that you are expecting?

Anton I have to say that your support is amazing in first place.
I have used other "dongles" to get information from OBD on this car. Speed, battery, odometer, etc.
As for firmware I'm using v5. Tried pointing to traccar ports and to freematics but no luck.
Maybe I'm missing something but would appreciate if you could help in anyway by pointing to some documentation or by any clue so I can dig a bit more.
I'm just an enthusiastic willing to explore the huge potential of this solution.

Just to confirm, you are using telematics protocol, right?

I don't think you need any additional configuration. Could be some hardware issue.

Protocol I think I'm using freematics as stated in devices page.
I followed instructions from https://www.traccar.org/freematics-configuration/ and I'm able to see position correctly.
But no other OBD data.
I will reconfigure device and test again in the morning tomorrow.
Hopefully will be able to post some logs.
Please let me know in case you have any additional advise.

Thanks

You can try to check device log to see if there are any errors.

unfortunately so far I'm unable to make SD work so far.
Will buy a couple of new SD tomorrow to be able to get to those logs..

Many thanks

How could I change the protocol? to use telematics as you suggested?

Anton Tananaev4 years ago

There is "telelogger" firmware that uses freematics protocol, but there's also "traccar_client" version of firmware which uses OsmAnd protocol and doesn't support OBD data. You need to use the former.

great...
I'm using telelogger.
will test tomorrow

Hi Anton,

Unfortunately I'm still unable to make the SD card work.
but here's the log from the server for positions table:

9	osmand	1	2021-11-08 05:23:00.0	2021-11-08 05:22:52.0	2021-11-08 05:22:52.0	true	25.******	51.******	1.9313	0.0	0.0		{"batteryLevel":93.0,"distance":1.74,"totalDistance":6.59,"motion":false}	40.53085986528376	null

Kind of strange that speed and course shows 0.0 all the time.
Also no ODB data on attributes. Is it supposed to show there or any other table?

On the events table I also only get 2 types deviceUnknown and deviceOnline. Is there any place to check how to configure more on the xml? or should they come from default?

And apparently telelogger uses osmand...

Thanks

Are you sure it's not from your mobile phone. Do you have Traccar Client installed somewhere?

Sorry.My mistake.
You are absolutely right. That log was from 2 days ago.
After rechecking I have 2 different sets of data, without changing any configuration:

1954	freematics	2	2021-11-10 03:50:46.0	2021-11-10 03:50:46.0	2021-11-10 03:50:46.0	true	25.******	51.******	6.0	7.18143	351.0		{"obdSpeed":9.719226,"rpm":695,"throttle":12,"engineLoad":28,"io270":"18","battery":14.73,"acceleration":"-0.19;-0.02;-0.06","deviceTemp":5.300000000000001,"sat":11,"hdop":10,"distance":4.03,"totalDistance":6243196.97,"motion":true}	0.0	null

4741	freematics	2	2021-11-10 13:54:34.0	2021-11-10 13:54:34.0	2021-11-10 13:54:34.0	true	25.******	51.******	7.2	7.18143	133.0		{"battery":14.55,"acceleration":"0.00;0.04;-0.22","deviceTemp":5.2,"sat":12,"hdop":7,"distance":3.71,"totalDistance":6271309.33,"motion":true}	0.0	null

so basically, speed and course are showing and I had some OBD data but then was gone for some reason.
What could be the reason for this difference? And are these the only possible values? I know there is a lot more data on OBD.

Don't know, but sounds like it's not a hardware problem if it was working at some point.

And are these the only possible values? I know there is a lot more data on OBD.

What makes you think there are more? Which ones are you expecting and missing?

I understand. Just would love to have more consistent results. will keep on trying.

What makes you think there are more? Which ones are you expecting and missing?

As previously shared, I used another "dongle" before to get some insights of the data available. Things related to cruise control, gears, ignition status, oil pressure.. There is a lot more for sure
