Hi,

you need a pic-controller a gsm-modem, like MC35i Terminal (Siemens) or similar or a mobile phone, and max232- IC or similar to connect this both together. The pic and the mobile phone communicate over a serial- connection. You need minimum the write- read- and ground- wire. If you want to use SMS to do the secure alarm you have to send AT-Commands from the pic to the gsm- modem.

Regards,

Tomas

What module are you going to use?

What is size of your SMS messages?

Are you going to send AND receive SMS from the PIC ?

First select the mobile to be used. Then get their pdf to see the AT commands. After that things are pretty easy. Connect the mobile as an RS 232 device and control it from a PC or a PIC (do not forget the MAX232 chip!).

An example would be:

HSerout ["AT+CMGL=",34,"ALL",34,13] 'Check if there is new SMS

or:

HSerin 5000,ex_sms2,[wait("READ"),skip 4,waitstr command\10,skip 27,STR command\6\13] 'Check for number in waitstr command\10

Hi! The examples that gave you were from a big program that does many different functions. I cannot send the whole code. I sent an example of how easy is to communicate with your mobile, given that you have an elementary experience with AT commands and serial communication. If you do, then also you will need the AT-commands set for the mobile you are going to use, so as to be sure of the commands and syntax needed.

If you decide the above then I guess it is easy as shown to use PicBsic Pro to do the job.

I do not see how can a hex code of the example be of any use to you just like that. You need a whole program setup, variables and data exchange...

Ioannis

thank you MR. Ioannis for your reply,

i will test it and return you.

thanks again.
