Abstract: The disclosed systems and method provide for an audio playback device to form a Bluetooth connection with an audio source device based on audio generated by an acoustic transducer. The audio is encoded with Bluetooth connectivity data corresponding to the audio source device. The acoustic transducer can be arranged on the audio source device, or it can be arranged on an audio playback device connected to the audio source device via a Bluetooth connection. The audio is received by a microphone of an audio playback device. The audio playback device then extracts the Bluetooth connectivity information from the audio, and forms a Bluetooth connection with the audio source device. If the Bluetooth connection is a Broadcast Audio stream, as defined by the LE Audio standard, multiple audio playback devices can be able to connect audio source device, allowing for a communal listening experience.

Abstract: Systems, devices, and methods for initiating an action based on location of a first device are provided. The first device, such as an earbud, includes a Bluetooth receiver. The Bluetooth receiver is configured to receive a wave signal transmitted by a second device, such as a smartphone. The first device further includes a processor. The processor is configured to calculate a location of the first device relative to the second device based on the wave signal. The processor is further configured to determine a zone status of the first device based on the location of the first device relative to the second device and a predetermined zone. The processor is further configured to initiate the action based on the zone status.

Abstract: An audio system, method, and computer program product for synchronizing device clocks. The systems, methods and computer program product can establish a first isochronous data stream between a peripheral device and a first device and establish a second isochronous data stream between the first device and a second device to send data between the first and second device. As the two data streams may rely on two different device clocks, e.g., one clock which defines the timing for the first isochronous data stream and a second clock which defines the timing for the second isochronous data stream, the systems, methods, and computer program disclosed herein are configured to maintain synchronization and/or synchronize the first clock with the second clock to prevent data loss due to clock drift.

Abstract: Methods and systems for improving the robustness of wireless communications. The methods and systems provided transmit data packets over a first isochronous stream and transmit one or more supplemental data packets over the same time intervals. The one or more supplemental data packets are used to re-create and/or enhance at least a portion of one or more data packets of the plurality of data packets that have already been sent. Alternatively, the one or more supplemental data packets are used to create and/or enhance at least a portion of one or more data packets of the plurality of data packets that will be received during the next isochronous intervals. The methods and system described herein allow for increased robustness by allowing for better retransmission with correctly received packets and the methods set forth herein work with any Bluetooth broadcaster sink without modification.

Abstract: Methods and systems of acknowledgment of wireless data packets is provided. For example, such a method can include receiving, from a central device, such as a smartphone, at a first peripheral device, such as a left earbud, a first isochronous data stream intended to be received by the first peripheral device. The method further includes receiving, from a central device at a second peripheral device, such as a right earbud, a second isochronous data stream intended to be received by the second peripheral device. In some examples, the second peripheral device is a right earbud. The method further includes eavesdropping, via the second peripheral device, the first isochronous data stream in an attempt to receive a packet of the first isochronous data stream. The method further includes sending, from the second peripheral device, an acknowledgment after the packet has been received by the second peripheral device.

Abstract: An audio system and method for retransmission of data packets between audio devices. The audio system includes a source device, a first audio device and a second audio device configured to receive an isochronous data stream from the source device. Each audio device is configured to eavesdrop or otherwise monitor the packets within the isochronous data stream meant for each of the audio devices and each audio device can retransmit packets from one audio device to the other in the event one audio device fails to receive a packet. The audio system is configured to operate in at least a partial retransmission mode or a total retransmission mode where the partial retransmission mode allows each audio device to selectably retransmit packets between audio devices and where the total retransmission mode requires one audio device to retransmit all packets to the other audio device.

Abstract: Systems and methods for broadcasting wireless data via one or more retransmission schemes to increase the packet reception in a wireless system. One or more devices of the system are configured to listen for an initial data packet from a source device. Should one or more devices successfully receive the initial packet, each device that received the packet can unconditionally retransmit a copy of the payload of the initial packet such that any device that failed to receive the initial packet payload has an opportunity to receive it during the respective retransmissions. Similarly, each device of the system can send acknowledgements to the other system devices that indicate whether they received the initial packet. Should one or more of the devices successfully receive the initial packet, the devices can conditionally retransmit a copy of the missing payload when one or more devices indicates they have failed to receive it.
