Re: Need an idea for my final Project!!Interfacing PDA-->
Hi,
other choice is USB, but bluetooth .. i don't know how good is the idea, if you want wireless communication, can use the IRDA port.
Made bluetooth receiver will be more difficulty, you can use standard one, this is easy, in this case you must only write soft for PDA, and if this is standard bluetooth to RS device, you must see it as a COM port in your PDA, then you will have a simple RS communication.
