FIG. 9 illustrates a flow chart of an example of a method for connection establishment between wireless communications devices, implemented in accordance with some embodiments. As discussed above, source devices 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 900, may be implemented to establish a first wireless connection that may be a Bluetooth connection, as discussed above.

Method 900 may commence with operation 902 during which it may be determined if a designated Bluetooth protocol is supported by both the source and sink devices. In various embodiments, such a determination may be made based on one or more interactions between the source and sink devices. For example, the source device may query the sink device to determine its capabilities. In one example, it may be determined if the source device and the sink device both support an A2DP Bluetooth protocol. If it is determined that they do support the designated Bluetooth protocol, method 900 may proceed to operation 904.

Accordingly, during operation 904 a Bluetooth connection may be established. As discussed above, the designated Bluetooth protocol may be an A2DP Bluetooth protocol. Accordingly, during operation 904, an A2DP connection may be established between the source device and the sink device.
