Bluetooth: Does Milo use it to connect to other Milos?

Milo doesn't use Bluetooth for communicating with other Milos, because Bluetooth does not give enough range. Instead we created a custom long-range mesh network to make sure the Milo-to-Milo connections are reliable over a longer distance.

Milo does use Bluetooth 4.1 to pair with the Milo app and for pairing with wireless headsets.
