  • Publication number: 20200344618
    Abstract: A device implementing the Bluetooth packet transmit optimization with simultaneous channel sensing may include at least one processor configured to transmit a first packet over a first channel in a first time period; perform channel sensing on a second channel in a second time period subsequent to the first time period; apply a remedial action to a transmission of a second packet based on the channel sensing; and transmit the second packet following the applied remedial action. The subject system utilizes some of the following potential remedial actions, such as 1) deferring transmission of a next Bluetooth frame, 2) increasing the packet transmission power, and/or 3) modifying a transmission packet type or packet length. A method and computer program product implementing the subject Bluetooth packet transmit optimization is also provided.

  • Publication number: 20200068491
    Abstract: System, method and computer-readable storage medium including, a first communications device including a host processor to wake up upon receipt of a message and stream audio directly to another device via wireless communication, a second communications device including circuitry to control the streaming of the audio by sending messages to the first communications device and to control a display. The host processor of the first communications device enters a sleep stale during audio streaming while a state of the display is off. Reduction in the number of messages sent by the second communications device, or offloading, of message handling by the host processor, allows the host processor to remain in a steep state for longer periods.

  • Patent number: 10517048
    Abstract: A device includes circuitry configured to transmit advertisement data to one or more electronic devices at a first advertisement rate. A presence or absence of the electronic devices is detected within communication range of the device based on a detection signal received from at least one of the one or more electronic devices. A predetermined advertisement rate is modified to correspond to a second advertisement rate based on the presence or absence of the one or more electronic devices.

  • Patent number: 9924303
    Abstract: An electronic device includes circuitry configured to determine that a first codec associated with a signal corresponds to one of one or more codecs supported by another device that is connected to the electronic device via a first communication link. A signal path is configured between a radio device configured to receive the signal and the electronic device based on a correspondence between the first codec associated with the signal and the one or more codecs supported by the another device. The signal is transmitted to the other device via the first communication link encoded with one of the one or more codecs supported by the other device.
