@rogue299: Yes, that's one of the common uses for this. If you're talking about data tethering, make sure you're using a smartphone that supports it and note that if you're phone has a USB tether or Wi-Fi hotspot option, both would be faster than tethering over Bluetooth.
Also if you're inot robotics? This lil device will help out alot if you're use Aurdino and Ez-builder for building and controlling your robotic overlords ;)
