lantrix problem ACK

Santiago8 years ago

I have a problem with a lantrix tracker, it sends the location normally but the server does not respond to the ack.
Could someone help me solve this problem?

I would need documentation.

Attached link to the documentation provided by the manufacturer. On page 5 talks about the format of the ack, Unfortunately it is only available in Spanish. I hope you can help me

Funny story. I have just implemented it yesterday.

My English is not very good with sarcasm. What did you mean to tell me?

Anton Tananaev8 years ago

It's already implemented.

Should I download a more recent version? I'm currently using 3.10 or maybe it's another reason why it does not work for me.

Anton Tananaev8 years ago

There is no more recent version. You should either wait for next release, or compile it from source code if you have enough technical knowledge.

I'll try! thanks for your time.

Eh I tried to compile myself and replace tracker-server.jar but I still do not respond correctly to the ack.

I have the doubt of doing something wrong. Maybe you can compile for me, to see if the problem is solved

Thank you

I will compile it for everybody with the next release. If you need it urgently, send me an email to discuss it.

Dear, I managed to make my lantrix work with Traccar
But you have to modify some lines of your source code where
Make the ack string

I attach the lines that worked for me.
Maybe you want to add them to the next release: D

   if (deviceSession != null) {
            if (sendResponse && channel != null) {
                if (messageIndex != null) {
                    //String response = ">ACK;" + messageIndex + ";ID=" + uniqueId + ";";
                    //response += Checksum.nmea(response) + "<";
                    String response = ">ACK;ID=" + uniqueId + ";#" + messageIndex + ";";
                    response += "*" + Checksum.xor(response) + "<";
                    channel.write(response);
                } else {
                    channel.write(uniqueId);
                }
            }

            return position;
        }

Saludos
