Watch protocol problem

How are you

I started using China GPS with the watch protocol, but I had a problem.
Location information is incorrect, others are correct. The most important location information is 0.00000 and 0.00000. What should I do?

Please provide logs. Also, do you have protocol documentation?

Thank you very much for your reply.
I have a protocol document.
When I went to the countryside to test GPS, it worked normally.
Do not find location in the city.
The GPS location update time has been set to 3600, but the latest update on the device's state is quickly changing than 3600 seconds.
what does it mean Could this cause the battery to run out of power quickly?
Are there any settings on the platform to help save battery power?
Please help me.

Why would there be some server configuration to save device battery? How would it even work? It sounds like a device issue to me.

thanks for your reply.
