hello guys...
from past few days I'm working on TCP\IP protocol using sim 900 to develop GPRS based data logger system.
My aim is to develop client-server and server-client based n\w system.
For that purpose I've downloaded Desktop application "terminal.exe" and tune it in server mode to listen client, which is my sim 900 modem then after i fire at commands for sim 900 modem to force it in client mode to establish connection with server through server IP,
and it's working good and I'm able to send and receive data to server and from server.
Now consider second situation, I'm tuning my desktop application in client mode and force GPRS modem in server mode by sending at commands. The problem is when i try to connect client(application) to server(GPRS) through server IP(GPRS modem IP) then my client shows connection time out message!
can any one help me to find out problem,:bang:
I'll appreciate all precious comments:-D
