<R59> doesn't seem to be the right rule for disallowing bluetooth on the OI, as it deals with custom circuits on the robot.
Section 7.13.1 bans two-way radios, but that's about all that I can see in the rules concerning off-board devices. Like Joe said, it's pretty clear from the rest of the rules that the controls (and things that interface with them) are not covered as custom circuits (see <R57>).

I don't think Bluetooth would be a problem, technically speaking, because it operates at 2.4 GHz (not 900 MHz like the radios) and uses pseudorandom frequency-hopping at 1.6 KHz between 79 channels (as a security measure).

As a practical matter, Bluetooth could be one more manifestation of the unwritten rule that communication from outside the alliance station is not allowed. (The team in question isn't asking to do this, but I'd speculate that FIRST wants to avoid this situation.)
