Hi,

I wrote a TCP server application in C#. If I am using a telnet prog I can send data to the server application and receive data from the server application.

However whenI use hyperterminal to connect my SIM340 module to the server application through GPRS, I can receive text from the server, but when I send text using the AT+CIPSEND command, it looks like I receive nothing on my server?
I get SEND OK after I sent my text, that is the weird part :p

To read incoming data to my server I use a streamreader that reads the networkstream of my client (the gprs module).

Also in the TCP/IP application note, they talk about a SIMCOM server application. Any idea where to get the app? It would be handy to see if I am able to send data to their app or not.

Thanks in advance!
Mathieu
