摘要

Systems, methods, and devices seamlessly playback data files using one or more wireless connections. Methods include establishing a first wireless connection between a source device and a sink device, the first wireless connection using a first transmission protocol and transmitting audio data via the first wireless connection. Methods further include determining a switch should be initiated based on one or more signal quality metrics, the one or more signal quality metrics representing, at least in part, an estimate of a quality of the first wireless connection. Methods also include switching to a second wireless connection between the source device and the sink device, the second wireless connection using a second transmission protocol, and the second wireless connection using data packets encapsulated for transmission in accordance with the second transmission protocol.

Moreover, first devices 110 may start at a distance greater than distance 140, and may move to be a distance from source 150 that is less than distance 140. In this example, system 100 may also be configured to identify such a change, and seamlessly switch between communications modalities during streaming of the data such that they may switch from using Wi-Fi to using Bluetooth, which may be more energy efficient. It will be appreciated that while FIG. 1 illustrates first devices 110 and second devices 120, system 100 may include only first devices 110 or second devices 120. Moreover, system 100 may include only one of first devices 110 or only one of second devices 120.

FIG. 2 illustrates an example of another system for seamless playback between wireless communications devices, configured in accordance with some embodiments. As similarly discussed above, a system, such as system 200, may be configured to include various wireless communications devices that are in communication with each other, and are configured to utilize wireless communications connections to stream data. More specifically, such wireless communications devices may be configured as one or more source devices and one or more sink devices. As will be discussed in greater detail below, a source device may move or change distance from a sink device, and system 200 may be configured to compensate for such changes in distance.
