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.

Method 900 may proceed to operation 906 during which it may be determined if AMP is supported by the wireless communications devices. As similarly discussed above, such a determination may be made by querying the device's capabilities and determining if both the source device and the sink device support AMP. If it is determined that AMP is supported, method 900 may proceed to operation 908 during which first Wi-Fi discovery operations may be implemented, as discussed in greater detail below with reference to FIG. 10. If it is determined that AMP is not supported, method 900 may proceed to operation 912 during which second Wi-Fi discovery operations may be implemented, as will be discussed in greater detail below with reference to FIG. 11.

Returning to operation 902, if it is determined that designated Bluetooth protocol is not supported, then method 900 may proceed to operation 910 during which a connection may be established in accordance with another Bluetooth protocol may be implemented. For example, if it is determined that the sink device does not support A2DP, a Bluetooth Low Energy connection may be established, and method 900 may then proceed to operation 912 discussed above.

FIG. 10 illustrates a flow chart of an example of a method for Wi-Fi discovery, implemented in accordance with some embodiments. As discussed above, source device and sink devices may implement various different operations for the purposes of establishing wireless connections. Thus, according to various embodiments, a method, such as method 1000, may be implemented to establish a second wireless connection in accordance with first Wi-Fi discovery operations, as discussed above.
