Abstract
Messaging between a companion device and an accessory device is controlled such that different modes of communication may be utilized. The different modes can implement different messaging strategies, each of which is intended for efficient power management, in view of the limited electrical power that is typically available at the accessory device. A received request message for sending from the companion device to the accessory device is sent if predetermined conditions apply, and similarly for messages from the accessory device to the companion device.
