Hi All,
I want to set up communication between GSM/GPRS modem and a remote server or PC. How to do that? Do we need some application on PC which will communicate to the GSM modem. I want 2 way commuinication. I want to interface GSM/GPRS modem with some microprocessor which has some LCD display. Can anybody help me in this.
Thanks, Manoj
Your question is pretty broad and covers a range of technologies.
Communicating with a GSM Modem
A GSM modem will connect to a computer using a serial or USB port. You can open the serial port and talk with it. Since you didn't specify platform, I can't suggest how to do that. In c#, you would use the SerialPort class. You use the standard AT* command set for various operations with it.
Communicating with a GPRS modem
A GPRS modem connected to external device will normally be on internet. If you know the IP address of target device, you can use TCP/IP sockets for communicating with it.
I want to interface GSM/GPRS modem with some microprocessor
Not sure what exactly you mean by that but if you want to program a processor for GPRS/GSM communication, you will need to understand that processor and write or buy a TCP/IP stack.
I think as the previous answer says you need to be more specific:
If you want to communicate with the GPRS modem itself, then you generally need a physical connection between whatever machine wants to talk to the modem and you would use regular modem AT commands (you could conceivably want to remotely control a modem but I am guessing this is unlikely).
More likely you want to communicate between a device (e.g. a computer) connected to the GPRS modem and a remote server. Provided your GPRS modem is working correctly you simply need to treat the GPRS modem as you would a regular interconnect connection. In other words your computer will now be able to use its browser (for example) to connect to a remote server just as it would if you were connected by a cable to your local LAN.
