Abstract: Various arrangements for using a short-range wireless communication link are presented herein. A wireless communication device can transmit data using an asynchronous connection-oriented logical transport (ACL) of the short-range wireless communication link. Monitoring for a high throughput event on the ACL of the short-range wireless communication link can be performed. Based on detecting the high throughput event on the ACL, a first physical layer (PHY) symbol rate of the ACL can be increased to a second PHY symbol rate.

Abstract: Features described herein pertain to systems and methods for wirelessly providing an audio stream. When audio that is to be output to an audio output device is associated with an application a set of parameters for modifying an established Connected Isochronous Stream (CIS) of a wireless link between an audio source and the audio output device can be determined and the CIS of the wireless link can be modified based on the set of parameters. The audio that is associated with the application can be output to the audio output device using the modified CIS of the wireless link.

Abstract: Various arrangements for performing wireless device-to-device communication are presented. An audio output device, such as an earbud or pair of earbuds, can establish a connection with an audio source via a first Bluetooth interface that communicates using a Bluetooth communication protocol on a 2.4 GHz Bluetooth frequency band. The audio output device can negotiate that Bluetooth frequency-shifted communication, such as on a 5 or 6 GHz frequency band, is available for use with the audio source. The audio output device may then perform Bluetooth frequency-shifted communication with the audio source such that the audio output device receives an audio stream from the audio source using Bluetooth frequency-shifted communication and the Bluetooth communication protocol.

Abstract: Various arrangements for short-range wireless communication are presented herein. An earbud of a pair of true wireless earbuds can receive an audio packet addressed to the other earbud of the pair. A single connected isochronous stream (CIS) within a connected isochronous group (CIG) may be present between the pair of true wireless earbuds and an audio source which transmitted the audio packet. The earbud can transmit a cross-acknowledgement indicating receipt of the audio packet to the other earbud. The earbud can also transmit audio data from the audio packet to the other earbud after the cross acknowledgement.

Abstract: The present disclosure provides for detection of conditions, and triggering role switch between wirelessly paired devices in response to detection of particular conditions. In response to detection of particular conditions, a primary device may switch roles with a secondary device. Such conditions may include battery level of each device, signal strength of each device, audio buffer levels, whether the devices are being worn by a user, whether a microphone is active, historic data, or any combination of these or other conditions.

Abstract: Various arrangements are presented for increasing a link margin of a wireless audio link. A short-range wireless communication link having a first physical layer (PHY) symbol rate is established between an audio source device and an audio output device. An audio stream is transmitted using the communication link, which includes a connected isochronous stream (CIS) link. A number of packet retransmissions are detected on the CIS. Based on the detected number of packet retransmissions on the CIS, the first PHY symbol rate of the CIS can be altered to a second PHY symbol rate for transmitting the audio stream.

Abstract: A communication device (202) comprises one or more sensors (208) configured to generate sensor data, a wireless interface (206, 306), and a processor (210, 310). The wireless interface is configured to establish a connection with a remote device (402) according to a short-range wireless communication protocol and to transmit one or more signals to the remote device, the one or more signals representing information configured according to a media format. The processor is configured to determine at least one activity mode based on the sensor data from the one or more sensors on at least one of the communication device or the remote device, and during the transmission of the one or more signals, control the wireless interface to increase a transmit power level to a maximum transmit power level based on the determined activity mode.
