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...
HI,THIS IS KK I HAV PROBLEM WITH 2 SIM 508 MODULES USING GPRS.JUNK WAS SENDING IN BETWEEN THE AT COMMANDS THIS CODE IS WRITTEN IN ARM LPC 2378
Unless KK is the same as Mohit Rawat, this is the wrong thread. Create your own thread, and deactivate the caps-lock key and then write a proper problem description, followed by any questions you have and possibly relevant parts of source code.
Right now, you haven't even explicitly said if the ARM is sending the junk characters or the GSM module. And you haven't said what AT commands and if you wait the required time between the commands etc...
But once more: One problem, one thread. And don't reuse other peoples thread unless your problem is identical and you can supply solutions or better descriptions how to reproduce the problem.
