I've been trying to make this SIM5320A module send HTTP requests to my server but even though it appears connected to the internet I can't seem to ping any server or make any requests.
I'm sending AT commands through a terminal on my Linux PC.
AT+CPIN appears READY
I've configured through the AT+CGDCONT, AT+SOCKSETPN = 1 and AT+CGSOCKCONT commands, adding my service provider's APN.
AT+NETOPEN returns OK. Running it again returns Network is already opened.
AT+CPSI? show's that it's connected to the WCDMA network and is online.
AT+IPADDR throws a proper IPv4 address.
So I'm trying to do AT+CPING="google.com",1 but it just won't connect.
I've even been able of sending a SMS and reading GPS coordinates, just failing in the internet stuff.
Am I missing any configuration steps? There is so little information online on this device.
