How do I check which SSL Certificate my SIM800 module has by default using ATCommands? How do I enable to use HTTPS GET using ATCommands?

Question

I want to get information from a particular web-page using HTTPS GET via GPRS connection using SIM800 Module connected to my Arduino Uno. For using HTTPS, I read somewhere that I need to have the right SSL certificate. I wanted to know is there any way using which I can view the SSL certificate which is there by default in SIM800 Module using AT Commands? Also, how do I enable it to use HTTPS GET, because I get ERROR message when I used AT+HTTPSSL and AT+CIPSSL.

Answer 1

You can use secured connection on arduino if you have GSM module which supports secured connections. Unlike the other answer said you CAN use arduino to make secured connections. These are the commands I use in SIM800 series module.

For https connection use " AT+HTTPSSL=1 "

For secured tcp connection use " AT+CIPSSL=1 "
