A computing device may include an accessory radio that facilitates point-to-point wireless connectivity between the computing device and one or more accessory devices. The accessory radio may periodically broadcast its presence to the one or more accessory devices while operating in an active state. The accessory radio may transition from the active state to a sleep state after a period of inactivity. The computing device may also include a general purpose radio that may facilitate general wireless connectivity between the computing device and other devices. The general purpose radio may listen for any messages that are intended for the accessory radio while the accessory radio is in the sleep state. The general purpose radio may activate 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.
