Microcontroller › 8051 › Interface of SIM 300 with 8051
i want to know how to interface SIM 300 module with any Microcontroller. i have connected Sim 300 to PC using RS 232 and sent messages via hyperterminal.
Can anyone give me interface diagram of SIM 300 with 8051? and a small code in which a sms is sent when a port of the uC is made high/low. Thanks in advance !!
