During a download sub-interval of the sub-intervals, and update packet can be received that includes new parameter data. During an upload sub-interval of the sub-intervals, transmitting an update response packet indicating the new parameter data has been received. Wireless operations of the wireless device can be configured according to the new parameter data. Communications can continue with the same advertising link while operating according to the new parameter data. Corresponding devices and systems are also disclosed.

Abstract: Disclosed are techniques to setup and use a BLE based wireless network between central devices of multiple piconets to exchange information to coordinate air-time usage by the piconets of the central devices. The information exchanged may include channel maps that indicate frequency channels that are available for use by the respective piconets, slot availability masks that indicate future air-time slots for use by the respective piconets based on a common time reference, and other meta information used to coordinate regulation of air-time usage. The multiple central devices may collaboratively regulate their respective air-time usage based on the exchanged information to reduce the potential for air-time clash. In one aspect, the central devices may use the periodic advertising with response (PAwR) protocol in BLE to exchange future air-time usage information. The timing of periodic advertising packets may provide a time reference for the multiple central devices to coordinate their air-time usage.

Abstract: Implementations disclosed include techniques and systems that include obtaining a connection event length for a wireless connection associated with a plurality of devices. The techniques and systems further include adjusting, using the connection event length, a parameter characterizing a quality of the wireless connection.

Abstract: A method can include monitoring at least one non-primary advertising channel for packets; determining if any of the packets received during a same periodic advertising interval of a periodic advertising link include synchronization data; in response to acquiring a packet with synchronization data, extracting synchronization data from the packet with synchronization data; and synchronizing to the periodic advertising link with the synchronization data to determine timing for at least one download window in each periodic advertising interval. The periodic advertising interval includes a plurality of periodic sub-intervals and the at least one download window corresponds to at least one of the sub-intervals. Corresponding devices and systems are also disclosed.

The at least two Bluetooth controllers are communicatively coupled to the host. Each Bluetooth controller is configured to wirelessly communicate with at least one respective external device.

Abstract: Disclosed are techniques to use existing BLE broadcast-based signaling protocols to achieve sub-1 ms peripheral-to-central latency even when multiple peripheral devices share the air-time. The techniques adapt existing BLE advertising or broadcast signaling protocols to efficiently allocate air-time to support frequent peripheral-to-central transmissions that are relatively short in duration and less frequent central-to-peripheral transmissions. A broadcast isochronous group (BIG) protocol may be used to reduce peripheral-to-central latency by aggregating broadcast isochronous streams (BIS) from peripheral devices into a BIG. A one-to-many broadcast event that may carry other broadcast data from the central device to the peripheral devices may be used for time synchronization by the peripheral devices and to configure time parameters of broadcast from the peripheral devices. A reverse many-to-one broadcast from the peripheral devices to the central device may be based on the time parameters.

Methods include determining, using a processing device, state information identifying a state of a first wireless device, and determining, using the processing device, that a data packet should be sent to a second wireless device based on an identified change in the state information. Methods may further include generating, using the processing device, a data packet for transmission from the first wireless device to the second wireless device via an isochronous wireless channel, wherein the data packet is configured to include the state information identifying the change.

Abstract: An approach is disclosed for providing bearer selection and transmission parameter configuration between a wireless terminal and a computing device. A request message is received from the computing device that is configured to execute a plurality of applications, wherein the request message specifies selection of a bearer channel and quality of service (QoS) requirement to support one of the applications. In response to the received request message, the bearer channel is configured with the QoS requirement, wherein the configured bearer channel is established for the one application.
