I recently bought a 'TinySine 3G shield (SIM5320E) 900/2100Mhz' based on Adafruit_FONA libraries to use with Arduino Mega 2560 R3. It successfully registered with Vodafone AU. Other functionality works (SMS, GPS) but not HTTP/TCP.
I'm following this TCP/UDP section of SimCom tutorial to receive data from a REST API. But I cannot set the APN for TCP as there is no support for
AT+CSTT command as it seems.
I can see it's on WCDMA network.
AT+CREG? +CREG:1,1 AT+CPSI? +CPSI: WCDMA,Online,505-03,0x014E,xxxxxxx,WCDMA IMT xxxx,xxx,xxxx,0,12.0,97,12,18,500 OK
Error comes here
Is there a way to resolve this issue - With the same setup/libraries OR - By upgrading libraries/firmware of the module OR - Using any other set of commands
Please provide if any of you have a sample code to access a REST API. Appreciate your help very much.
