I’m having problems to get the GPS working in my HL6528RD module. It gives me back an error every time I try to send any gps related commands.
I can read these commands:
+CME ERROR: 3
I’ve tried in 3 different modules and it’s always the same response. Driving the module through UART, the GPRS works fine.
I can’t find any other commands than: “AirPrime HL6528RDx - AT Commands Interface Guide” but none of these AT commands seem to work for the GPS.
