Listening Socket by AT | Thales IoT Developer Community

January 28, 2018 - 10:39am, 2324 views

I want to setup a listening socket with AT Commands.

Unfortunately the examples in the AT pdf are confusing and don't work.

AT^SISS=0,srvType,"Socket"
AT^SISS=0,conId,0
AT^SISS=0,address,"socktcp://listener:80"

AT^SISO=0
^SIS: 0,5

AT^SISO?
^SISO: 0,"Socket",3,3,0,0,"1.2.3.4:80","0.0.0.0:0"

I can't connect to 1.2.3.4:80  , tried different hosts and programms
telnet 1.2.3.4 80
***** - TCP4-CONNECT:1.2.3.4:80

Connect Timeout and No Unc  / ^SIS Message

In Knowledge Base there is no Server / Listening Example and the Client Example uses 
AT^SISS=0,"srvType","Transparent"
while AT pdf uses "Socket"
