saikiranra is correct, through the maximum number of connections is slightly more complicated. The number is usually seven, but can vary between devices. A good brief explanation can be found at http://superuser.com/questions/33276...uetooth-device.

Each of the super scout tablets (red and blue) is connected to the three scout tablets for the alliance. The scouts are able to transfer their files via this connection to the super scout. In addition, the scouts can request the competition schedule from the super scout, which is then sent from the super scout to the scout. For the technical details of how the bluetooth connection works, I would recommend looking over the Bluetooth connection code in the scout and super scout apps. Below are links to the files that control most of the Bluetooth connection.
