Hi,  
Please retest with the latest FW. and I suggest first to check AT+KTCPCNX=1. Here’s my log for your reference.

Hi,  
Thanks for your answer, I want to send the data(GET / POST) through a session and get the response immediately from the server (End to End Secured Connection).  
Anyway, I’ve upgraded the FW to BHL7800.3.4.1.2.20190509 and I finally got it working , I’ve followed the below AT commands :

-AT+CGATT=0

- AT+KCNXCFG=1,“GPRS”,“lpwa.telia.iot”

- AT+KCNXUP=1

-AT+KTCPCFG=1,3,“213.32.68.232”,443,1

+KTCPCFG: 1

OK

- AT+KTCPSTART=1
