Abstract: Communication between a source device and one or more pairs of accessory devices and between accessory devices within pairs of accessory devices is scheduled using slot availability masks (SAMs). A primary accessory device provides to the source device information about requirements for communication between the primary accessory device and a secondary accessory device. The source device determines a SAM map that specifies a periodic cycle of time slots, with time slots marked as available or unavailable for transmission and/or reception. The SAM map satisfies requirements to avoid collisions between communication between the source device and the accessory devices and communication between accessory devices within pairs of accessory devices. When multiple pairs of accessory devices establish connections with the source device, internal communication between accessory devices within pairs of accessory devices are aligned to use at least a common overlapping set of time slots.

Abstract: A method and system for an improved communication mode for Bluetooth wireless devices is disclosed. Packets used in the improved communication mode are encoded using a convolutional encoder and transmitted with a particular modulation index such that the improved communication mode provides an improved link margin with respect to a communication mode specified in a Bluetooth wireless communication protocol. In this regard, the improved communication mode allows Bluetooth wireless devices to continue to communicate when a communication link between the Bluetooth wireless devices degrades, whereas otherwise the connection would be dropped. Furthermore, the Bluetooth wireless devices seamlessly switch between the improved communication mode and other Bluetooth communication modes without renegotiating the connection.

Abstract translation: 公开了一种用于蓝牙无线设备的改进的通信模式的方法和系统。 在改进的通信模式中使用的分组使用卷积编码器进行编码，并以特定的调制索引进行传输，使得改进的通信模式相对于蓝牙无线通信协议中指定的通信模式提供了改进的链路余量。 在这方面，当蓝牙无线设备之间的通信链路降级时，改进的通信模式允许蓝牙无线设备继续通信，否则连接将被丢弃。 此外，蓝牙无线设备在改进的通信模式和其他蓝牙通信模式之间无缝地切换，而不重新协商连接。
