Chinese Clone: Receiving data but not getting processed by traccar

I need to know what zero there means.

From the manual : the data valid bit (0 / 1), 1 indicates that the GPS positioning data is valid data, 0 data indicates that the GPS positioning data is not valid.

Please provide the manual.

do not have it here, will post tonight

Sorry i can not find it anymore, think it has thrown out by accident. Is it possible to make it work without the manual?

Sorry, but I need official documentation to implement it.

Okay, can't i modify it on my server and re-build?
I have sent 2 requests to the manufacturers now.

Of course you can modify it yourself if you want.

is there a guide somewhere how to re-compile the jar?

Yes, there is. Please use search before asking questions.

I have found the protocol information. This bit represents the Coding scheme: 0: GB2312, 1: Unicode, other: Undefined

You can find it here: https://cloud.mdlonline.nl/index.php/s/DM5jV2X2HEdZyRN
on page 8.

But what about "the data valid bit"?

I think i read it from a manual from different gps tracker. This is the manual from the manufacturers of this tracker. Sorry for that

I have added support for this format.

Thanks. Where can I donate
