Bluetooth at competitions

[nathanwalters]

Hello all,
Some other students and I on my team are currently working on designing an electronic scouting system to replace our old paper-based one. Originally, we were going to use a flash drive connected to our Android tablets via and OTG cable, but that plan fell through because Android does not seem to support hot-swappable external storage. We are currently exploring our other options; Bluetooth seems to be one of them. Can anyone confirm once and for all whether or not Bluetooth is allowed at competitions? I've seen conflicting information on this site and want to be totally clear on what is and isn't allowed at competitions.
