hello guys,

I am trying to make a project that sends a message to a cellphone number when a door or window is opened.
I am using pic18f4620 and sim500w GSM module.
When i run it on simulation it's ok but on the actual hardware it doesn't work, it becomes stuck at the first part of the program.
Please help and thanks in advance
 

you should provide your mcu code and hardware diagram.
that could be helpful for you
 

First of all find out that it is software problem or hardware.
1) use delays in your code.
2) use rs232 or lcd or any thing else and send current status of micro-controller on lcd or rs232.
3) connect noise filters in your micro-controller power supply and make shore that microcontroller is running on +5v.
 

Post the datasheet of SIM500w. How did you simulate GSM in proteus. Do you have GSM module in proteus or did you just check the serial communication in Proteus? Post you code so that we can see what is the first part of the program.
 

hello guys,
here are the datasheets of sim500w one is for the hardware and the other is for the software...
in simulating the GSM we used DCU-11 cable and connected it via COMPIM

here is my code :
