Can you set up Arduino for Blue tooth as well as wireless Ethernet?

Can you set up Arduino for Blue tooth as well as wireless Ethernet?

I want to be able to control Relays and Sensors mainly though Blue tooth or maybe even remote frequencies, but also be able to later do things over the net.

Thanks

Can you set up Arduino for Blue tooth as well as wireless Ethernet?

Are you asking for permission?

What hardware do you plan to use for wireless Ethernet? What hardware are you using for bluetooth?

Bluetooth is not a way to control relays and sensors. The Arduino can control relays, and read from sensors. It can communicate via bluetooth to some other bluetooth devices. What exactly is going to be on the other end of the bluetooth link?

but also be about to later to things over the net.

Well, good luck with that. Whatever that was supposed to mean.
