ATcommand GPRS PPP
-
Hi, I have a console application written in C language using Visual Studio. The application will reside in a laptop to dial up to the Internet using a PDA phone. The connection between the laptop and the phone is set up using the Bluetooth Dial-up Profile. I am able to make normal phone calls to a fixed house line and other mobile telephone number using the ATDT command. But I am unable to connect successfully to the ISP server through GPRS services. I am using the commands AT+CGDCONT=1,"IP","APN" and ATDT*99# (*99***1# is also tried). After issuing these 2 commands, I get a CONNECT response and then some unreadable characters appear. Then after a few lines of the unreadable characters, I get a NO CARRIER response. I would like to find out is there any commands that I left out? Or is there another way for me to set up the PPP link between my laptop and the phone? Thanks and regards, PS

After CONNECT you get PPP frame, and you should communicate using PPP protocol after getting CONNECT. I am looking for C# class to handle PPP, does anyone know where to find?
