HTTPS connectivity with HL7802

IoT Modules

I’m working on a Sierra Wireless HL7802 and am trying to perform HTTPS (SSL) to connect to remote server. However I receive an error message from the server during the communication phase.

Here are my AT commands :

AT+KSSLCFG=0,3
OK

AT+KCNXCFG=1,“GPRS”,““szsjmc.gd”,”“,”“”
OK

AT+KSSLCRYPTO=7,8,2,16384,8,4,1,0
OK

AT+KHTTPCFG=1,“server-name”,443,2,0"
+KHTTPCFG: 2
OK

+KCNX_IND: 1,1,0

AT+KTCPCFG=1,0,“server-name”,443"
+KTCPCFG: 3
OK

AT+KTCPSTART=2
CONNECT
HTTP/1.1 400 Bad Request
Server: Apache
Reason: You’re speaking plain HTTP to an SSL-enabled server port.
Instead use the HTTPS scheme to access this URL, please.

I would like to know if the problem is related to the configuration of the server or the modem.
Did you have a configuration suggestion ?

Thanks.

i think you should use some KHTTP command to connect to server:
