How can i communicate between two GPRS enabled,SIM-508 module, using AT command via hyper-terminal of PC.
This has nothing to do with Keil tools!
See: http://www.keil.com/forum/
There are basically 3 ways:
1. Using SMS messages;
2. Usind a Data Call;
3. Using GPRS.
(or combinations of the above).
You will find the necessary AT commands in the Documentation for the modules.
Most of it is standard, so any site dealing with such things will be of use to you...
<p>Yes i can use any of three as described above. But i want to communicate using GPRS only.But for that use i need at least one static IP for one module and another mayhave static/dynamic IP.</p> <p>But i want to do it with Dynamic IP alloted to both module from GSM service provider.</p> <p>so how cani achieve it</p>
Note that dynamic IP means that you must register your current IP with a machine with static IP somewhere. Look at dyndns.com for example.
But there is another problem. Dynamic IP may also imply that the module is firewalled so that it does not accept incomming connections, even if you know the IP. Because of this, you may have to do the actual data transfers too trhrough a third machine, so that both the modules performs outgoing connections to the common machine.
Sir,can you plz seuugest me some forum or web-link which related to AT commands query.
