PicoPix wake-on-BT?

Is there documentation on the PicoPix waking up on Bluetooth from the AirMote? Found out quite by accident, was idly playing around with the AirMote, and noticed that when I long-pressed the power button, the blue light on the PicoPix lit up. And no, I wasn’t pointing the AirMote at the projector, and the IR couldn’t have bounced off walls or floor or ceiling. Might’ve pressed for three-to-five seconds. Another long-press, maybe shorter than the three-to-five seconds that [b]might’ve[/] powered up the projector, on the power button, and the PicoPix powered up.
