EC200U return -0.0 in lat lon

Dear Quectel Community,

I am reaching out for assistance regarding an issue I’ve encountered with the EC200U module. When attempting to parse latitude and longitude data, the module sometime returns a value of -0.0. This unexpected result is impacting the functionality of my application.

I would be grateful for any insights or solutions regarding this matter. Has anyone else experienced similar issues with the EC200U module? If so, how were you able to resolve this? Any advice or guidance on troubleshooting steps that I might take to address this problem would be highly appreciated.

Thank you in advance for your time and assistance.

Kind regards,
Quang
