Does it work for 5320E ?

[nagaokashi]

It seem that can not enable 3G for 5320E ?

Yes, it should support SIM5320A and E versions. Did you use the "G" command in the LTE_Demo code first to enable GPRS then post with "3"?

Please be more specific and include what code you're using, AT command responses, etc.

• GPRS is no longer available in my country (JAPAN). I took a look into the Adafruit_FONA.cpp, instead of using "AT+CSOCKAUTH" for 3G, you used "AT+CGAUTH".

  
  // set username/password
        if (apnusername) {
                  char authstring[100] = "AT+CGAUTH=1,1,\"";
                  char *strp = authstring + strlen(authstring);
                  prog_char_strcpy(strp, (prog_char *)apnusername);
                  strp+=prog_char_strlen((prog_char *)apnusername);
  ......

This is my AT command

AT+CGSOCKCONT=1,"IP","3g-d-2.ocn.ne.jp" OK AT+CSOCKSETPN=1 OK AT+CSOCKAUTH=1,2,"mobile","mobileid@ocn" OK AT+CHTTPSSTART OK AT+CHTTPSOPSE="httpbin.org",80,1 ERROR

I have no ideal about this error and do not know how to debug.

[botletics]

Please try "www.httpbin.org" with the "www" and see if it works.

Hi @botletics . I tried but same result.

AT+CGSOCKCONT=1,"IP","3g-d-2.ocn.ne.jp"
OK
AT+CSOCKSETPN=1
OK
AT+CSOCKAUTH=1,2,"mobile","mobileid@ocn"
OK
AT+CHTTPSSTART
OK
AT+CHTTPSOPSE="www.httpbin.org",80,1
ERROR

If you have any ideal, please tell me.

Sorry, I am not 100% sure what might be wrong because users have reported the code works fine on SIM5320 and the same AT commands run on the SIM7500 as well.

Maybe you could try "www.dweet.io" instead? I know that works for me.

Did you get it working?
