Abstract: A technique for reducing latency of high priority asynchronous traffic in the presence of isochronous traffic of a Bluetooth™ Low Energy communications system includes communicating an Asynchronous Connection Link (ACL) payload using a Connected Isochronous Stream (CIS) event. A bit in a header of a host-controller interface packet indicates to the controller that an ACL packet is a high priority ACL packet. The controller replaces the payload of a CIS event with the payload of the high priority ACL packet and the controller encodes a bit in a header of the CIS packet to signal to the receiving device that a corresponding CIS event contains an ACL payload. The controller transmits the CIS packet in the corresponding CIS event and the receiving device applies ACL handling of the CIS event in response to decoding the bit in the header of the CIS packet.

Abstract: In one embodiment, a method includes: receiving, in a sink device, profile information regarding a communication from a source device; based at least in part on the profile information, determining, in the sink device, a size for a buffer of the sink device, the buffer for storing streaming data of the communication; based at least in part on the profile information, determining, in the sink device, a synchronization interval for the communication; and controlling, via the sink device, the communication of the streaming data from the source device to the sink device via a first wireless protocol based at least in part on the synchronization interval, to cause the sink device to be a synchronized receiver for the communication.

Abstract: A multi-protocol wireless communications system uses prioritization of isochronous streams to increase the reliability and improve bandwidth utilization. Placement of subevents in an isochronous interval according to link quality reduces fragmentation of the isochronous interval. A method for multi-protocol communications between wireless communications devices using a wireless communications interface includes placing in an isochronous group event, by a first wireless communications device, at least one subevent for each isochronous stream of a plurality of isochronous streams of an isochronous group based on a historical retransmission rate for each isochronous stream of the plurality of isochronous streams. The method may include counting retransmissions for each isochronous stream of the plurality of isochronous streams to thereby determine the historical retransmission rate for each isochronous stream of the plurality of isochronous streams.
