SIM 300 GSM Module

Sorry it was that instead of theat.

Plzzzzz anybody reply :-s

what about baud setup? you forgot that..!! printf wont work without it.

add this code in your main starting..

SCON = 0x50;
TMOD = 0x20;
TH1 = 0xFD; //if you are using 11.0592Mhz crystal
TL1 = 0xFD;
TR1 = 1;
TI = 1;

try again afterwards..

thnx for the reply.. bt still i m not able to send 1st AT command from the microcontroller... other commands are appearing properly on the hyper terminal screen.. and because of this problem i m not getting message on my mobile..

plz help...

first check if your controller is transmitting properly or not.

write a simple program to send 'A' on serial port and check its o/p at hyper terminal. get back with with results.

I checked it on hyper terminal, microcontroller is transmitting properly... but when i connect GSM Module, i m not getting anything on my mobile...:(

THANKS A LOT ....we got the output....i.e we are able to send a string on a mobile through microcontroller... !dance

initially we were using 20Mhz crystal but it was giving baud rate's problem so then we changed our crystal to 11.0592 MHz crystal as it was used in ur code...n now its working absolutely fine....

Now further...

we are going to read one register from ADE7754 IC and that value will be stored in variable...now...we want to send the value which is stored in variable to GSM Module to get that data through sms on mobile.....

so how do we proceed now?

Thanks in Advance

Read the variable IE 0x2a
Convert to an ASCII string of numbers. IE "2a" 0r "42"
Send as a simple text message.

But why did u take 0x2a?? i dint understand that...
