Abstract: The present disclosure provides systems and methods for transmitting data to a pair of truly wireless devices. A first device, which may be considered the primary device, may determine a first data packet was received. The first device may also determine the first data packet was not received by a second device of the pair of truly wireless devices. In response to determining the second device did not receive the first data packet, the first device may request the first data packet be retransmitted.

Abstract: Role switch between wirelessly paired master/slave devices may be performed without perceived glitches in audio. The devices negotiate an anchor point, such as a point in time or a point in relation to other events, for performing the role switch. To prepare for the role switch prior to the anchor point, the devices communicate a variety of information, such as information for communicating with the host device after the role switch and information for bit processing after the role switch. The slave device may use such information to serve in the master role, without the host knowing that a role switch occurred.

Abstract: A communication device (202) comprises one or more sensors (208) configured to generate sensor data, a wireless interface (206, 306), and a processor (210, 310). The wireless interface is configured to establish a connection with a remote device (402) according to a short-range wireless communication protocol and to transmit one or more signals to the remote device, the one or more signals representing information configured according to a media format. The processor is configured to determine at least one activity mode based on the sensor data from the one or more sensors on at least one of the communication device or the remote device, and during the transmission of the one or more signals, control the wireless interface to increase a transmit power level to a maximum transmit power level based on the determined activity mode.

Abstract: This document discloses technology generally related to an accessory that may wirelessly connect to one or more host devices such that the accessory is able to receive content from two or more of the host devices simultaneously. The accessory may have two or more wireless communication interfaces connected to two or more respective host devices via a type of wireless connection. The accessory may determine a time to simultaneously receive content from and/or transmit content to each of the host devices. The time may be determined by adjusting the start times for reception and/or transmission of content from the two or more host devices, and/or it may be determined based on the type of wireless connection. According to some examples, the accessory may determine a priority for each of the wireless connections using arbitration rules. The accessory may output the received content simultaneously.

Abstract: The present disclosure provides for detection of conditions, and triggering role switch between wirelessly paired devices in response to detection of particular conditions. In response to detection of particular conditions, a primary device may switch roles with a secondary device. Such conditions may include battery level of each device, signal strength of each device, audio buffer levels, whether the devices are being worn by a user, whether a microphone is active, historic data, or any combination of these or other conditions.

Abstract: This document describes an accessory that may wirelessly connect to one or more host devices such that the accessory is able to receive content from two or more of the host devices at the same or substantially the same time. When each of the host devices is wirelessly coupled to the accessory, the accessory and each host device may determine a bit rate for the accessory to receive content from each host device. The accessory may receive content from a first host device at a first bit rate. Based on the content received, the accessory may determine a new bit rate for other host devices.

Abstract: The present disclosure provides systems and methods for dynamically adjusting a bit-rate of encoded audio data. A buffer may receive audio data encoded at a first bit-rate. An audio data level corresponding to the amount of audio data stored within the buffer may be determined. The audio data level of the buffer may be determined to be within a buffer zone, and a bit-rate adjustment may be initiated after determining the audio data level is within a buffer zone.

Abstract: A system and method is provided for improving signal quality in communications among fully wireless systems including a host device in wireless communication with a primary accessory which further wirelessly communicates with a secondary accessory. The host device generates information for use by the primary accessory in determining which channels have interference and should be avoided. The information may include an adaptive frequency hopping (AFH) channel map for communications between the host and the primary device, from which the primary device can infer which frequency bands have interference and generate a second AFH map for communications between the primary accessory and the secondary accessory accordingly. In other examples the information includes the second AFH map generated by the host, for example, based on an out-of-band scan. In further examples, the information includes an indication of channels used by recognized nearby access points.
