Hi, I m connecting SIM300 Module with Hyper terminal using MAX232 circuitry. But when i open the terminal, it shows random ASCII characters before pressing any key as well as after pressing any key. Can anyone please help me in this ?
 

Ok. What should be the baud rate for SIM300 DZ ?
 

give the command AT+IPr=? and you will get a set of possible baud rates for sim300..... after you set the baud rate on the modem, set the same baud rate on hyperterminal... thats it...
 
SIM300 support 1200,2400,4800,9600.... Buad Rate
