We tried different port’s number but nothing change,,,
We did AT#SD=1,0,80,"www .telit.com" all gone well!
looking for some help!!
Have you tried to set first the firewall then listen?
Can you connect from anything else, a PC?
Yes i tried to active first of all the firewall but nothing change. About the connection from the pc i tried with a broswer to contact (on port 80) the IP but nothing happens…..
Try with telnet better, check the server module, there is no incoming connection?
Are you sure your SIM/subscription allow incoming connections, ie running server applications?
Try another firewall setup, for example:
Hi,Seems like vodafone block those type of connection, in fact we tried with another sim(TIM) and it works with the upper configuration! What do i need to ask to my provider to allow me to open socket on Telit module? Peer to peer or something like VoIP?
Ask for a public IP (you have it already) with the possibility to run server applications on your choice of ports (probably they can do it only on a limited set of ports), in other words to accept incoming connections. You will probably need to speak with a technical person at Vodafone not the normal customer service support, and you can expect to be forced to use a special subscription plan or extra option.
If you intend to connect many devices a VPN will be the best option, they have such offer in the business portfolio.
Thank you! we will try to ask them!
