Chinese manufacturers can use same model name for completely different devices, so you need to try and see if it's actually using GPS protocol. I use the protocol gps, port and works ok with the position, but not with the obd data, it is not stored. I have seen in the logs, that send 2 mesages, the first one send gps data, the second one two seconds later send the obd data.

If I use the hex decoder: The first one: imei,tracker,F, The second one: imei,OBD,13, Now I understand the problem. The OBD type is not supported yet.

I need protocol documentation to add support for it. I need to know possible value ranges. What values can be decimal? Are they always decimal?

Hex Decoder

I will tell you later. I have send an email to the seller ask him for the protocol document, but I am not very optimist in his answer. May I ask a stupid question? I also have that coban A and in the H2DB database. So it looks like the device can send OBD-data and traccar can store it. In state I can see e. But there are way more values coming in via GPRS, those are not shown in state. The values following "OBD" are imho those: comment.

That means: Almost all the incoming OBD values are correctly stored and got nice names too. Missing seems to be "power load: However: Almost none of them are shown in the "state" box. Sorry for the many updates of my comment above.

I really hope I can help with the debuggings I've made. The one you "sniffed" is an OBD message. The one that you are looking at in the web interface is a regular GPS message. Or is traccar not able to display the OBD-data messages if they come in as a separate data-message?GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

But traccar cannot decode the position HEX, or I'm using a wrong protocol? It's not a standard GT02 protocol. Looks like manufacturer has extended it. I would need to see protocol documentation. Here is a brief translation:. I found it, there is no " In short, you can just ignore the packge, but have to reply the packge clock synchronize.

No, it can't be simply ignored. I need to know the format to implement frame decoder. How do you know the message ends otherwise? Skip to content.

I got a additional documents, shows how to reply the and package. Thanks for your patience. OK, send me an email to discuss implementation of this protocol.

OK, now works My tracker sends zero coordinates because I'm still testing it and it is indoor But I received a sms a link with the correct coordinates. I wrote this information because it could be an error decoding the hexadecimal Do you have any suggestions?

You can try to look at traffic from device using Wireshark if you don't trust me, but I'm absolutely sure it's not a server bug.

I think it's either device firmware bug or you are using wrong command. Of course I believe in you, had captured the data with wireshark, but I was not sure I interpreted correctly reading the packet network. Excuse me if I expressed myself badly, I do not quite mastered the English language. I am have this device type TX-5 then I have a problem also with the terminal configuration setting to point the default www. That makes sense, I think someone already warned me about this "trackers" that don't really have GPS.

Someone has the right SMS commands?

Questions are: Can I use this device with traccar? If this device is not the right one, what device lbs-only should I use with traccar? Hi another time. Sorry for asking something that probably is in the documentation, but I have not found how to do it. Could you please give a clue about how to configure a geolocation provider for LBS, and if possible, suggest which provider to use?

Thanks a lot.

Identify Protocol

Thanks, for new info. I have tried to get an API key from opencellid but unfortunatly they have new registrations dissabled until 18th. So I tried to test it with mozilla. Not sure if I need also to ask for an API key or not, so I tried the following parameters, but still getting lat 0. Should 'test' key work? Protocol is H02, and decoding is working well. Also, if your device reports coordinates with LBS data, you have to enable processInvalidPositions flag.

Could you check it? Ok, now I understand what is happening. Anyway, I was going to return this device because is not accepting a server name, only an IP, so is not valid for me. I don't think you do. Even I don't. The message has "V", so it means that it's invalid, so geolocation should work. You are right, 'V' is there, so LBS decoding should work. Any option to get more log information to see why is returning 0.

And the following is what is showed in traccar web:. Wait, I think Traccar just doesn't decode the cell information. That's why it doesn't work. To support it, I need protocol documentation.I have managed to get them to work both with traccar but I cant find a way to get extra parameters like Estimated Odometer whch I am sure that it is supported by teltonika at least.

It doesnt work though. Does anyone have any idea how to get extra parameters from both teltonika and tk? Which port works for your TK?

If you provide a HEX message sample from log, I can check if it has odometer information or not. The 'io' regretfully didn't work. I am probably doing something wrong, so here is the whole query also for others to use :. And here is the teltonika HEX from the log: eddce2d4aaff8ceefcbee01cedde2d4c1a16affa0edfcabd01cedde2d4d0e16affa0effcf01ccb34a.

I am almost certain that odometer is enabled on FM because when I enabled it with the configurator, the HEX got larger slightly. As for the TK I think it is a GT02A but here is the HEX: eeeeec Could you please enlighten me on this? For TK, you should use port and it can report odometer, but in your sample the odometer value is 0. Thank you very much, I will look further into it for the teltonika tracker. I am also thinking of connecting a cheap thermometer on it arduino's lm35 and get some temperatures, so it would be great if I could decode it.

Thanks a lot for your time, you have been of tremendous help. Yours sincerely, Johnie D.

traccar hex decoder

I have decoded message through debugger, so you need to have some development skills to do it. Traccar decodes all Teltonika IO data, so you should be able to use thermometer as well. I am pretty skillful in python so I will try to decode it that way. I guess I have to break the text into substrings and decode it one by one according to the protocol right? If you want to debug it, I would suggest to take Traccar project source and put this HEX as one of the unit tests and run it in debug mode.

Can i avoid responding binary messages with sms or special cmd? You don't need to reply to any of those messages. I don't know if can avoid binary messages. Possibly not, but you should check manual or ask manufacturer. I check manual but it says the messages will be in hexadecimal - is this hex? No, messages are binary, but you can convert binary into hex string if you want.

Time is not correct and I can use server time as alternative. My main problem is Lat and Longitude which I'm trying to get for the past 3 days. Kindly help. Attached protocol screenshot for your ref. Kindly let me know after the above steps what am I suppose to do to get the lat and lon. Also, tell me plz whether I'm hitting the right index position in the byte stream for this lat and lon. Kindly give me some idea or tell me what message you need see.

I have attached the protocol spec. Anton, I have given the max information I can find. All I need is just a way to find this lat and longitude. Data getting is not correct and it exits saying unknown device. HEX raw data : eeeeec
