Abstract
This publication describes a vehicle computing system (e.g., a head unit, in-vehicle entertainment system, infotainment system, etc.) that may automatically switch from outputting audio to a single computing device using a wireless point-to-point protocol to outputting audio to two or more computing devices using a wireless broadcast protocol. The vehicle computing system may include multiple modules for controlling wireless connections (e.g., multiple BLUETOOTH controllers, WIFI controllers, etc.). Each user in the vehicle may have wireless listening devices (e.g., wireless headphones, speakers, earbuds, etc.) connected to at least one of the wireless controllers. For example, a user may have wireless headphones connected to one wireless networking controller and another user may also have wireless headphones connected to a different wireless networking controller. Both users may be listening to audio, with the computing system providing the audio stream for each user using the corresponding wireless networking controller. While connected to only one device, the controller may use a point-to-point wireless protocol, such as BLUETOOTH Low Energy (BLE) or WIFI Direct. However, if one of the users wants to listen to the audio another user is listening to, the vehicle computing system may automatically switch from using the point-to-point protocol to using a broadcast protocol, such as BLUETOOTH Auracast. The broadcast protocol may enable multiple connections to the same wireless controller, such that each user receives the same audio.
