Thank you for replying. As the title indicated, this is the AT command code for the Sim7600A-H GPS board.
The problem is I followed the instruction to use the A-GPS, but failed. The GPS didn't return the location instead, it just closed itself.
As there is no debug message, I know nothing about it. I saw a post here years ago so I wander if someone has sorted out. Not everything on the Earth is analysable, even the document/manual of this hardware doesn't specified what causes this.
