Can't get GPS coordinates with A7670E module
Hi, I’m testing my module A7670E 4G module with an ESP32-C3 Mini to get GPS coordinates.
I’m sending AT+CGNSSINFO in a loop, but the response I get is always:
+CGNSSINFO: ,,,,,,,,
Meaning there’s no GPS fix at all, even after several minutes outdoors.
I’ve already enabled GNSS with AT+CGNSSPWR=1 and set GPS mode with AT+CGNSSMODE=1,1.
The antenna is a small square ceramic patch (marked 1596A-T) — I’ve tried placing it outdoors and on a metal surface (like aluminum foil) but still nothing.
Has anyone encountered the same issue or knows how to reliably get a fix with this module? Any advice would be greatly appreciated! 🙏
