All of the GT06 data is getting filtered out

All the received data is getting filtered out with no position data making it to the database. Yes few of them do contain zero coordinates but i see even valid data is getting filtered. My device is called AT06N. I have identified the protocol to be GT06.

check device timezone

Thanks for the reply. I used GT06N and the behavior is same. I did change the device timezone but did not make any difference. Here are the logs.

Hi Anton,
How do I take this forward. How to debug this

Where is the valid data getting filtered?

OK. Checked the protocol in detail (12th bit of course status). GPS signal was not adequate in the location of testing as such the validity was 0.
Thanks for the reply.
