atrack protocol not reporting extra information

Adam 7 years ago

Hello!

Just got some atrack(AK11/AL11) devices and they are reporting to the server. However, none of the extra data OBD2 data is showing on the server.

I see the data report to the server when the device in in ASCII mode (but traccar doesn't understand it), the extra data is there though.

Any ideas?

Also... might not report it if the devices themselves are not offically supported. derp. I was hoping to see undefined fields at least.

Have you configured device to report additional data? Make sure you also configure it to report custom data format string to server.

Yes, I have. That's why I can see the data being sent (after changing it to ASCII mode). I'm changing the custom report to add the AT$FORM data, I'll report back to see if that changes anything.

That's binary data, not ASCII.

Adam 7 years ago

Yes, but the atrack protocol is only binary. If you try to send ASCII to that port, it doesn't work

Anton, could you tell us which is the process to decode binary protocol? Teltonika has a protocol like this.
I tried to convert binary to hex, but it was unsuccessful.
Maybe do you have any clue about it?

Anton Tananaev 7 years ago

Adam, as far as I know, Traccar supports both.

Peter, it's not possible to decode binary data into human readable text, if that's what you are asking.

Adam 7 years ago

Anton, I e-mailed you privately at support@ with an ascii logfile.
