Microcontroller › PIC › GSM and GPS helpp!!!!
I am running out of time can anyone help me setting up my gsm module i have tried a lot but can not make a call using it. i m using PIC18f4550.
Hi Ammar,
Connect the module to the Serial port of PC and using hyperterminal software, send the AT commands for call making and hence check whether the module is working or not.
I have connected the module it is working fine. I have also simulated the code using proteus its working too. But when I connect the controller and gsm module it does not work.
Please post your connection diagram.
