Error "An established connection was aborted, possibly due to a data transmission" | Telit Cinterion IoT Developer Community

I am trying to establish tcp connection by using your tutorial (

This is my configuration:


^SCFG: "Call/ECC","0"

After command at^siso=2, I always get "OK".

But, if I type "at^siso?", srvState is always 3 (which means connecting)

After some time I get an error "An established connection was aborted, possibly due to a data transmission".

But, if I now type "at^siso?", srvState is 6  (which means down)

What am I doing wrong?
