at commands sms

void init_serial_interrupt()
{
EA=0;
TH1 = 0xFD;
SCON = 0x50;
TR1 = 1;
RI=0;
TI=0;
ES=1;
TMOD = 0x26;
EA = 1;
}

void sr_intr() interrupt 4
{
if(RI)
{
dat = SBUF;
RI = 0;
}
if(TI)
TI=0;
}




This is Only for Receving SMS in SBUF.

AFAIK Nokia 3310 / 3315 will not support AT commands.
They use the proprietary FBUS protocol.

**broken link removed** , should get you started. Handling the data @ 115,200bps, may not be very trivial if you use a slow micro,with less RAM to buffer the inflow.
FYI this model is long discontinued.
Maybe its more relevant to try with another el cheapo model : 1200.
Have fun

dear gurpreet
vande matram....

thx for ur information.
i know how to get the data in SBUF already.
and thx for the code.

but now the point is --> if we get a data in text format, its not worth ( i feel so) so i got some information . we neeed to get SMS data in PDU format ( its binary) and with which we can make the action to operate a pin on MCU .

so if any one is aware of how to get a message ( at comands only) in PDU format. and decode it in MCU 8051 to make it meaningfull to operate a pin status.... plz comment.

i need only with AT commands and not with FBUS
