Sending data from 1 pic to other pic

i want send data from 1 pic to other pic using wireless comunication.
i want find the best way to send the data using bluetooth,IR,RF or other divice. can some one help me or give me idea

thank for help

IR would probably be the easiest of the methods you've mentioned in my opinion. Another wireless method is ZigBee if you want to look it up.

Your best bet would be to determine which method you would like to use as the first step. Determine how fast you want the communication to be, how much data you are sending, range of the communication etc etc

Cheers

Ah, in that case you probably won't want to be using IR! Sorry I can't be of more assistance as I've not designed any bluetooth applications. I think, but not sure, that zigbee was originally designed for lighting control so you may want to check this out first.

There are some people on this forum who have used bluetooth and may be able to help you decide what modules to purchase before you embark on your project. You may want to check out the bluetooth specific section as well.

Good luck

Hi Po,

Why don't you checkout Bruce's website: www.rentron.com. He has many products and examples on how to do it and he sells the materials! I think this is a good place to start.
