Google patents method to prioritize keyboard and mouse over audio in Bluetooth

Google has filed a patent application for a method to manage Bluetooth Low Energy bandwidth by prioritizing Human Interface Device (HID) traffic over audio traffic. The filing describes a system that detects conflicts between data from devices like keyboards or mice and audio streams, then gives priority to the HID data to reduce lag. This approach aims to ensure that both audio quality and the responsiveness of connected peripherals remain high simultaneously.

Why it mattersThis is interesting for users who connect multiple devices to a single Bluetooth hub, as it addresses a common issue where typing or mouse movements feel sluggish when audio is also playing.

In the filing’s own words

Various arrangements for managing Bluetooth Low Energy (BLE) bandwidth usage across different devices are described herein. The techniques described include prioritizing HID traffic over Close Isochronous Event (CIE) traffic. Generally, a CIE is used by a computing device (e.g., a call gateway) to indicate that audio traffic for the event has been successfully delivered and received by another computing device. Using the techniques described herein, the user experience can be improved by helping to ensure that not only the user experience of the audio traffic is good, but also that the user experience with other HIDs are good (e.g., improved HID latency).

What exactly they claim (claim 1)

1. A method for managing usage of Bluetooth Low Energy (BLE) bandwidth, the method comprising: establishing a Connected Isochronous Stream (CIS) connection to communicate audio link traffic between a first computing device and a second computing device; determining a conflict between the audio link traffic and Human Interface Device (HID) traffic; and prioritizing the HID traffic over the audio link traffic based at least in part on the conflict.
