thank you for reply Rob.

i want control 20 light and range 20 meter.. i can on and off the light using wireless and check the light already on or off.

Rob if u thing using ir more easy can u help me..

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

Rob
