Lpc2000

Hello Sir,

What is ur application.Do u want to send data to server by using GSM.
Ur GSM must be in GPRS mode.

First Check ur GSM by giving AT<cr><lf>.The GSM will respond with 
the same AT<CR><LF> with OK.

After Getting the Message u should know ur Network and Signal 
Strength.

give the commands AT+CSQ<CR><LF> and AT+CREG<CR><LF> and check the 
signal strength and the Network strength. After checking these 
things put ur GSM into modem and send the formate of AT Command.

After u receive CONNECT u can get or post ur data to the server.

On the server side ur page must receive the data.If u want u can 
give response in the UDP and that can be used as handshake.

I done these by sending data to the server by using GPRS.It worked 
fine.

I want to know more about ur projects, so that i can help u.

with cheers,
Rajendra R
