HOW TO WORK WITH "AT+CMGS=23" AND PDU MESSAGE
I AM USING PIC MICROCONTROLLER PIC 16F877A,4MHZ.
MY MOBILE IS OF SONY ERICSSON J300I.
MY PROBLEM IS -- I CAN SEND SMS USING AT+CMGS COMMMAND THRU HYPERTERMINAL BUT USING MICROCONTROLLER NOT YET SUCCEDED.
THE MICROCONTROLLER DIALS NO. CORRECTLY BY SENDING ATD=<DA> COMMAND.
ACTULLY, I DON'T KNOW HOW TO SEND THOSE BYTES OF PDU MESSAGES AS
ONE BYTE i.e. 0X0A (LENGTH OF DESTINATION NO.)OR ASCII OF O=30H AND ASCII OF A=41H.
