1. A computing device, comprising:
an accessory radio that facilitates point-to-point wireless connectivity between the computing device and one or more accessory devices, wherein the accessory radio periodically broadcasts its presence while operating in an active state, and wherein the accessory radio transitions from the active state to a sleep state after a period of inactivity; and
a general purpose radio that facilitates general wireless connectivity between the computing device and other devices, wherein the general purpose radio listens for any messages from the one or more accessory devices that are intended for the accessory radio while the accessory radio is in the sleep state, and wherein the general purpose radio activates the accessory radio in response to the general purpose radio receiving a message, while the accessory radio is in the sleep state, that satisfies at least one activation condition.
