@kunal

 

put your message receiving command in timer function.Timer will  repeatedly check the time and will display the message after every 15 minz. U will have to use the delay function or date/time function.

so can u please tell me how to use it??????

or tell me the source from there I can learn about it.

The best thing you can do is to setup serial interrupt..

 

no need of waiting 15m when the msg is comming.. serial interrupt will just wait the msg u want serially and run continously in the backgroun if there is no msg…

but i dont want to receive sms. I WANT TO SEND THE SMS AFTER EVERY 15 MINUTE.

After every 15 minute, sms should be sent from microcontroller….

Which language are u using??

[Kunal]

I am using ASM language.

if you dont want to receive sms then just use any available timer in you controller..

 

measure 15m delay then tel your serial interrupt to send the msg every 15m
