Single chip microcomputer controlled by short message

This is a function that sends a byte.

{

SBUF = sdata

while（TI = = 0）；

TI = 0；

}

send（“AT+CMGF = 0 \ r \ n“）；

send（“AT+CMGS = 25 \ r \ n“）；

Send a byte function, where you use it to send a string?

Don't rush to send the things sent by the single chip microcomputer to the mobile phone module.

Send it to the serial assistant of PC first, and see what you send.
