Abstract

The present disclosure relates to optimized Bluetooth scheduling for accessory devices. Specifically, a slot availability mask (SAM) is used to schedule communications between a source device and one or more pairs of accessory devices, and communications between accessory devices within multiple pairs of accessory devices. The primary accessory device provides information to the source device regarding requirements for communication between the primary accessory device and the secondary accessory device. The source device determines a SAM map specifying a periodic cycle of slots marked as available or unavailable for transmission / reception. The SAM mapping satisfies the requirements to avoid conflicts between communications between a source device and an accessory device and communications between accessory devices within pairs of accessory devices. When pairs of accessory devices establish a connection with a source device, internal communications between accessory devices within the pairs of accessory devices are aligned to use at least a common overlapping set of time slots.

Description

technical field [0001] The described embodiments set forth techniques for scheduling communications of devices in a Wireless Personal Area Network (WPAN), including optimizing communications between a source device and one or more sets of accessory devices. (BT) connection. Background technique [0002] Wireless communication capabilities continue to be added to a variety of devices, including accessory devices that can be configured to pair with the source device. For example, a wireless audio reproduction device such as wireless earbuds may be connected to a source device, such as a smartphone with media streaming capabilities, tablet, laptop, or other wireless-enabled computing device, to receive the audio stream via a WPAN connection, such as via a Bluetooth connection. The wireless earbuds may also communicate with each other via a separate WPAN connection, such as another Bluetooth connection. The two Bluetooth connections can form a scatternet, where a source devic...
