I am using traccar 6.6 ubuntu version and have turnt of ignition and odometer in the GPS software.
I am experiencing issues with this GPS GV57MGV2, while attempting to connect it to the Traccar platform.
In the Traccar logs, the GPS device appears to be returning an empty string.

I have configured the GPS to communicate using the GL200 protocol on Traccar, but the connection does not seem to work as expected. I would appreciate your assistance in resolving this issue.
Looks like we don't expect some fields to be empty. Do you have the protocol documentation for your device?
I don't have the official documentation for the protocol, but I have seen claims on some websites that it uses the @Track Air Interface Protocol.

We are currently waiting for a meeting with the company to clarify how to fix the issue, but the process is taking a long time.
