Hello everybody. I would like to interface PIC with a Nokia mobile via FBUS to send and receive SMS. I have collected two schematics.
Which one do you recommend? Is there any enhancement need to make?
Thank you.[/img]
hey the circuit need not b that much complex u dont wory abt the tx pin of the phone.
u just have a resistor and diode(remeber 2V7) for the rx of mobile .that will work
