Chinese gps watch

I’m trying to add a Chinese GPS watch to traccar but with no success. Read all the documentation about the clone devices and used the hex converter but now I’m stuck. The HEX string is

ff41515348002b0100000077644d6bb975ca08e83abee9eb59e61bd9628c57dada406635f946694d354c865dbc4339a3

and I configured it to use port 5093 of my server. The Hex converter returns a weird string. The watch is connected as i can see in the server log. Ive tried the device id. Imei and the solution with the leading 0 for the imei with the last 11 numbers of the imei. All with no success. Anybody who can help me with this?

This has been discussed many times. Protocol is not supported yet because we don't have documentation.

Hi Anton,
please find a link to A19 communication protocol documentation.

That's wrong documentation.

I wonder Anton, why is that the wrong documentation ? Isnt it the communication protocol ?

Any update @rene? I have the same issue
