AT commands for HTTPS

Question

I've been working with a SIM808 and sending HTTP GET requests using the following AT commands:

"AT+HTTPPARA=\"CID\", 1\r\n"
"AT+HTTPINIT\r\n"
"AT+HTTPPARA=\"URL\",\"http://www.example.com/\"\r\n"
"AT+HTTPACTION=0\r\n"
"AT+HTTPREAD\r\n"

and it works fine . But when I replace the URL with https, I only receive "OK"

My question is if there is a way to use AT commands for HTTPS request methods (using SSL).

First, you should terminate an AT command line with only \r and nothing else, see [this answer](http://stackoverflow.com/a/21503919/23118). — hlovdal, Aug 26 '16 at 22:43
Could you include the code you use to send commands/read responses? — hlovdal, Aug 26 '16 at 22:45
@hlovdal I have been using \r\n for years and it has worked everytime. and the documentation of this module says specifically that the AT commands start and end with — Francisco Estêvão, Aug 29 '16 at 10:02
@hlovdal is the code really necessary? cause it's really long... I believe I'm receiving and sending everything correctly. my question is only if there is possible to send HTTPS — Francisco Estêvão, Aug 29 '16 at 10:06

The answer is to execute AT+HTTPSSL=1 after setting the URL. Hope this helps someone

Thanks @Francisco, How to pass a custom key via AT Command? I tried this way, `AT+HTTPINIT` `AT+HTTPPARA="URL","WWW.XYZ.COM"` `AT+HTTPPARA="CONTENT","application/json"` `AT+HTTPPARA="AuthenticationKey","mykey"` This line is not working. – Rudra Mar 26 '18 at 13:50
