Variation of Xexun Protocol

Jess-UK8 years ago

I have purchased what is claimed to be a tk106 tracker and have installed traccar server (confirmed working via iphone / android clients).

I have configured the tracker to send data to traccar and can see it is being received in the log file.
looking at the format it appears to be a variation of the xexun data string (same layout to start with but missing data after imei)

sample data from log file

yes the unit really does send HI to the server as it starts up (not seen anyone else mention this)

What coordinates do you expect to see? Do you expect 0 longitude value?

Jess-UK8 years ago

approx position of the tracker is 53.082697 / 0.113305
possible ones from the strings would be the 6th and 8th

looking at the typical xexun strings they appear to match up to the end of the imei

I have fixed the problem. Here is a new build:

Many thanks for the swift response Anton

Traccar is now recognising the data from the tracker perfectly

Spoke too soon, there is an error in the parsing of the longitude where it rolls from 9 to 10

I hope this makes sense...
9.4151,E is translating as 0.15692 which appears to be correct
10.1423,E is translating as 1.00237 which is quite a way out (it should be somewhere around 0.16)

Image is of a short trip testing the tracker in a car (I can assure you we didn't drive in the sea)
Ooops

Please provide HEX message samples.

Here's a sample of the problem occurring from my log files (error first appears at 11:25:12)

new build installed and working for my home location, I will be able to check for the rollover error tomorrow and report back.

edit :
I used a tool to fake a couple of packets to traccar (repeats of old packets with modified time data) which would previously have caused the error, they all positioned perfectly

Just thought I would pop back and let you know that the new version worked perfectly, thanks again for your help.
