Unable to read sms from GSM which is interfaced to 8051

Hi deep0177,

In your code, you have write one function read_text to read SMS message, right.
I think the second do while loop has problem.

do
msg++;
while(*msg!='+'); // reaching at no

Now think what happens in case of +CMGR: "REC READ","TD-610401","","12/08/24,10:52:41+22" .

Regards,

The garbage character problem can be because the power supply reference for the mico controller and the GSM modem are different. Try shorting the ground pins for mico controller and GSM modem. I think it should work.
