Abstract: Methods, systems, and devices for wireless communications are described. One method may include determining that a quality condition of a primary Bluetooth-enabled device is lower than a quality condition of a secondary Bluetooth-enabled device. The primary Bluetooth-enabled device may transmit, to the secondary Bluetooth-enabled device, a handover request message based on the determining. The handover request message may include a subset of connection information associated with a connection between the primary Bluetooth-enabled device and a device in wireless communications with the primary Bluetooth-enabled device. The primary Bluetooth-enabled device may receive, from the secondary Bluetooth-enabled device, a handover response message based on the handover request message. As a result, the primary Bluetooth-enabled device may handover, to the secondary Bluetooth-enabled device, at least one logical transport channel of the set of logical transport channels based on the handover response message.

Abstract: As many applications, such as wireless headsets used with cellular phones, require mostly error free data to accurately reproduce a telephone conversation, uncorrected erroneous data packets may impact a perceived quality of a given application. The error correction techniques of the present disclosure promote error-correction in communication systems that lack FEC with respect to one or more portions of a data packet. The techniques therefore provide error correction for the entire packet, including those portions not protected by any imbedded error correction mechanism. As a result, data communications over noisy communication mediums may be improved as the techniques may reduce bit error rates, and increase the sensitivity of the receiving device such that the transmission power of a data packet may be reduced. For voice packets or other streaming data packets, the techniques promote improved audio quality over systems that do not employ the techniques described in the present disclosure.

Abstract: According to various aspects, an isochronous channel may include an update slot in which a source device may schedule a transmission to broadcast control information to one or more sink devices. As such, a sink device may initially listen to a periodic advertising stream to receive synchronization information to acquire or re-acquire the isochronous channel and subsequently synchronize to the isochronous channel according to state information that the source device conveys in the update slot.

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.
