EHS5 and SISO fails to open | Telit Cinterion IoT Developer Community

January 16, 2020 - 1:59pm, 1422 views

I'm trying to connect to a server at 10.0.100.11:1883.

When I invoke the AT^SISO command to open an internet service it ***** out.

I can ping other systems like google.co.uk, I can FTP from other systems but cannot make the connection to this server. 

I can change to another server and connect ok and go into transparent mode but when I revert back to the original server it still fails to connect.

Firmware is 3.001-14.
