Finding the proper protocol and port for a cheap chinese TK103B tracker

mdtahmid7 years ago

Dear Anton
I can't stop appreciating the endless support you have been providing to all these users will all sorts of issues and questions in this forum. Thank you for being there.

I have been using your software for providing tracking solutions to my clients. So far I have successfully used a wide variety of devices using multiple protocols (osmand, TK103, GT06A) and have implemented the trackers in many vehicles.

I recently ordered a few TK103B trackers from AliExpress that goes by the name Dytech and Dyegoo. Someone in the forum mentioned that some similar device uses TK103 protocol on port 5002 and uses the ID 0+last 11 digits of the IMEI. I tried ports 5001, 5002, 5006 and 5023 but no luck whatsoever. When I use port 5002 or 5001 I get the following messages in Traccar log and that's it. Take a look and see if you can me a solution. Thanks again! :-)

Cheap Chinese Tracker

Okay I have seemed to solve the problem. I used the full 15 digits IMEI as the device ID and port 5023 (GT06). It now seems to provide me data correctly now. Cheers! Anyone facing this issue can try this solution.

You should use 12-digit id (0 + last IMEI digits) ONLY with TK103 PROTOCOL, which means it only makes sense to use it on port 5002.

Hi, I also have a tk103b, did it work for you on port 5023 or 5001?

Please help me, thank you

Why not try both?

It does not work for me, I have tried with the 15 digits of the IMEI and also adding a continuous 0 of the last 11 digits of the IMEI.

Funciono utilizando el protocolo H02 puerto 5013. En el número de identificador utilicé los 15 digitos de IMEI.
