sir my project is to automatically send an sms through gsm modem to the doctors mobile using a microcontroller whenever the threshold limits of blood pressure,temperature,heart beat etc are crossed so please suggest which microcntroller to be used and the mobile to be used and the necessary circiut with source code
I don't have source code for this.
how can we connect gsm modem to mobile phone or should we use any memory to store the phone no of the receiver????
sir thank u sir for ur valuable suggestions and also tell about the above ques sir plssss
No, that is not generally true!
You must read the datasheet (or "user manual" or whatever) for the specific make & model of modem that you are actually using!
P3.0 (RXD)connect this pin to pin no 9 of MAX232 IC P3.1 (TXD)connect this pin to pin no 10 of MAX232 IC
this assumes a specific package (pin numbers are different for difrerent packages)
Erik
thank u sir for ur
I have been looking all throught this thread for that microresistance (ur) and see no contribution from micro (u) to thank him for.
sravani, you are almost overly polite with the 'thank yous' and the 'sirs' and then you destroy the whole thing by continuing in gobbelygook which is an insult any adult human being.
