Help needed to identify protocol

Frank5 years ago

Hello everyone,

I've been trying a lot of protocols before posting.
It is a chinese GPS Tracker so it should be one of the clones but I cannot decode the HEX. It just gives weird unreadable text

In the log is:2020-10-11 09:08:29 INFO: [4459c8f8] connected
2020-10-11 09:08:30 INFO: [4459c8f8: xexun < 192.168.89.1] HEX: 78780d010352672102200268008860c30d0a

If I try to decode: 78782222140a0b07081acd057708ae0092170200140000ce1404ee006e400000000087c0c10d0a
I get: [binary data]

I hope someone can help me with this...

Read this: https://www.traccar.org/clones/

Your device is using GT06 protocol, as far as I can tell.

Also, HEX decoder only works for text-based protocol. Your one is binary.

I've tested GT06 before but it looked strange (not like my other trackers)

I retested it now and now it works...

Many thanks for your help!
