I agree, there needs to be a way to prevent any random tablet/phone from connecting to a random IOIO board, simply by knowing the passkey is 4545. Has anyone successfully implemented this yet? I have an application where the IOIO will be controlling parts of an electric car so it is critical that noone except my tablet can connect to the IOIO. I would like to use bluetooth because it provides convenient electrical isolation between the 800V battery pack and the tablet on the dashboard of the car.
