Problem with protocol

Hi,

i am using a lot of sinotrack trackers like th 901,902,905,915 and they all perfectly work with the h02 protocol on port 5013

I have bought a Sinotrack ST-908, but that doesnt work on H02 protocol/port 5013. also tried gt06(5023)without luck. i have followed the instructions on identifying protocol, but i got stuck. i pulled the Hex files below from the server logs:

2019-12-25 23:29:52  INFO: [f5f87430: gt06 < 188.207.72.51] HEX: 2929b10007449345700c580d
2019-12-25 23:29:58  INFO: [f5f87430: gt06 < 188.207.72.51] HEX: 292980002844934570191225232957052088430051362300000299ffff000082fc0000001e78080e000034220d

but if i put those in the HEx decoder, i do not get a usefull output. Can somebody please help me figure out this protocol? or maybe someone knows which protocol it uses? it is a christmas present for my sister, so hope to figure this out soon.

thanks in advance and merry christmas!

to add to the above, the supplier has send me this document about the protocol. Hope someone can help me how to use this tracker. Thanks!!

With help from anton i at least got location updates over the khd protocol(port 5058)

hope the full protocol will be supported in the future. If people want to share the costs of anton implementing it(+-200 dollar) i am open for that!

This seems like a khd protocol and not gt06. most of this vendors sometime change stuff when they do different variants.. Will test with the document shared and revert.
