GSM interfacing

[Gebreabzgi Pawlos]

hallo for every one

i am student of university. am studying EEE and i am new for the proteus software.when i came to my question:-

i have tried to work a project which is GSM based project but while i tried to simulate in proteus software i can't find the GSM component some one who have an idea about my problem welcom and thankyou for your help!!

Hey Gebreabzgi Pawlos,

Simulation GSM component not available in proteus. But if you have GSM module and you want to communicate with proteus then it is possible.Click on  library of proteus and serach 'COMPIM'.Select it and enter configuration by double click on it.Connect your GSM modem with PC and check communicate port by go on 'manage' by right click on computer icon.same configuration make in proteous COMPIM.Now you can direclty communicate with GSM module from proteus.You can also interface COMPIM with controller and test your application through proteus.

i have spent a lot time to study about it but no best books that explains about GSM interfacing (GSM communication) if u have any refferences about it can u share me if u dont mind?

 

with best regards

Hey Gebreabzgi Pawlos,

GSM interfacing with microcontroller is very simple. First check what protocol supprted in your GSM module (i.e, RS232 , TTL , UART). If your module has TTL output then direct cross connect TX and RX pin of GSM to  microcontroller's TX and RX pin and make the common ground. If your GSM has RS232 support then connect with controller through MAX232(TTL to RS232) converter.If you want to interface with PC then directly connect RS232 cable and open hyper terminal .If COM port of GSM found,you can test GSM module by AT command.

Hey Vara  Ashishkumar i would like to say thankyou for your help

but the links that you give me are both on hardware based but i dont have a capacity to buy the GSM module. i am trying first to simulate all the components of my project with proteus then by revising (seeing) my instructor my project he is going to report to the university inorder to buy a GSM module and other all components what i have order him. and first i should have to complete all the simulation that doesnt requier hardware.

here you will help me the procidures in simulation of GSM interfacing with 8051 (i.e AT89C51).

 

I dont have words to say thankyou

Hey Gebreabzgi Pawlos,

You can't develop your application without GSM module.You want to first test in proteous but GSM module not present in proteus.But if you want another part of your application rest of GSM,you can do it. Almost GSM module is communicate with controller through UART port.So learn the configuration and make code for serial communication. You can test in proteus using virtual terminal connect with controller's serial port.
