Abstract: A method for muting a Bluetooth device is described. The method includes receiving, by a Bluetooth controller of the Bluetooth device, a mute remote microphone message from a peer Bluetooth device. The method also includes disabling audio transmission functionality of the Bluetooth device. The Bluetooth device may also receive a disable remote mute message from the peer Bluetooth device and enable the audio transmission functionality of the Bluetooth device.

Abstract: A method for wireless communication by an advertising Bluetooth (BT) device is described. The method includes detecting an energy level that indicates a corrupt connection request sent by a remote BT device. The method also includes determining that there is a failed connection attempt based on the corrupt connection request. The method further includes performing connectable advertising at a faster rate to allow the remote BT device to reconnect quickly.

Abstract: This disclosure provides systems, methods and apparatus for clear channel assessment (CCA) enabled narrowband (NB) communications. In some implementations, a device is configured to associate with an NB channel (such as a Bluetooth channel), perform a CCA to assess whether the NB channel is clear, and transmit on the NB channel when clear. If the NB channel is not clear, the device may prevent transmitting on the NB channel. The device may prevent avoiding the NB channel after the first time that the NB channel is not clear. If the NB channel remains not clear (such as over a number of CCAs for the NB channel), the device may avoid the NB channel by removing the NB channel for FH for an amount of time. In some implementations, the device may be configured to perform frame based equipment (FBE) CCAs for one or more NB channels.

Abstract: This disclosure describes a first slave device that transmits information to a second slave device indicating that a first data packet was improperly received from a master device, so that a corresponding data packet may be relayed from the second slave device to the first slave device. In an aspect, the second slave device may receive a first data packet followed by an indication that the first slave device improperly received the first data packet, where the second slave device is configured to relay the first data packet to the first slave device in response thereto. In another aspect, the second slave device may receive a request to listen for a separate data stream of the first slave device based on a first data packet being improperly received by the first slave device and transmit a second data packet of the separate data stream to the first slave device.

Abstract: A first device may establish, with a second device, a first logical link associated with short-range communications. The first device may detect the transmission of a first packet from a master device to the second device carried on a second logical link. The first device may decode at least part of the first packet comprising data intended for the first device. The first device may transmit, to the second device, a request for a re-transmission of the first packet when the first device fails to decode at least part of the first packet. The first device may receive, from the second device, at least one re-transmission of the first packet. The first device may apply an error correction operation on the at least one re-transmission of the first packet received from the second device and the first packet received from the master device.

Abstract: A method for communication by a scanner is described. The method includes receiving a broadcast message from a broadcasting device in a connectionless mode. The method also includes performing back channel communication with the broadcasting device on a contention basis while maintaining the connectionless mode. The scanner may send a packet to the broadcasting device while maintaining a connectionless relationship with the broadcasting device.

Abstract: Methods, systems, and devices for wireless communications at a wireless audio device are described. A first (e.g., primary) wireless audio device may initiate a role switch procedure with a second (e.g., secondary) wireless audio device. The first wireless audio device may disable traffic flow between the source device and the first wireless audio device and transmit synchronization information and timing information necessary for taking over the role of primary wireless audio device to the second wireless audio device. The first wireless audio device may transmit a device role switch message, and the first wireless audio device and the second wireless audio device may perform the role switch. After performing the role switch, the first wireless audio device may assume the role of a secondary wireless audio device and the second wireless audio device may assume the role of a primary wireless audio device.

Abstract: This disclosure provides methods, devices and systems for signaling modulation schemes and stream parameters such that the modulation schemes and stream parameters can be adapted dynamically while maintaining an existing wireless connection. Some implementations include signaling, via a first channel, a set of stream parameters that govern communications on a second channel when a particular modulation scheme is used to modulate the packets transmitted via the second channel. A transmitting device may select a respective set of stream parameters for each of multiple modulation schemes. For example, in addition to an initial modulation scheme and set of stream parameters, the transmitting device can select alternative modulation schemes and sets of stream parameters that are optimized for the respective modulation schemes. The transmitting device signals the modulation schemes and the respective sets of stream parameters via the first channel in advance of switching modulation schemes for the second channel. The transmitting device is enabled to change the modulation scheme and the set of stream parameters on the fly by including an indication of the modulation scheme in the next packet it transmits via the second channel.

Abstract: Two devices (e.g., two wireless Bluetooth earbuds) may exchange device address information (e.g., Bluetooth address information) and may identify a primary address. When either of the devices connect to a source device (e.g., a phone), the primary address may be used by the connecting device such that the pair of devices appear as a single device (e.g., a Bluetooth-pairable device) to the source device, regardless of the device connecting to the source device as the primary device. The primary device may then send identity information (e.g., that has been exchanged with the secondary device) to the source device, such that the source device may connect to either of the two devices. Further, once a primary device connects to the source device, the primary device may transmit, to the secondary device, connection information such that the secondary device may connect to the source device and operate in the primary role.
