currently, i am doing a fire detection system. </I was wondering is it possible to use keil to send an SMS to a phone user?> I am currently now using 8051 Micro-p and Keil C programming. I have established an interface between micro-p and detection system.
Well, it can certainly be done – I have done it. You will need a GSM transceiver that can be driven through from your 8051's serial port. There are transceivers available that can be driven using "AT" commands with extensions for GSM/SMS. If you post your e-mail address perhaps we can exchange some tips.
"There are transceivers available that can be driven using 'AT' commands with extensions for GSM/SMS." The GSM specifications define the AT Commands that must be supported by compliant terminals; this link cites some relevant specs: http://www.8052.com/forum/read.phtml?id=32043
