Bluetooth® technology has been the cornerstone of wireless human interface device (HID) solutions for nearly two decades, enabling the widespread adoption and commercial success of plug-and-play wireless keyboards, mice, gaming controllers, and more.
To address the needs of evolving or more sophisticated, latency-sensitive HID applications, Bluetooth is introducing two new features that enhance its HID capabilities and allow supporting HID report rates of 1k or better. The first feature, HID ISO, leverages the transport and synchronization advantages offered by Bluetooth LE isochronous channels to enable faster HID report rates via a Connected Isochronous Stream. The second feature, HID SCI, exploits a new Bluetooth LE core specification (not based on isochronous channels) that permits the configuration and fast modification of ACL connection parameters to adaptively adjust HID report rates in an application.
This session will provide an overview of HID ISO along with an early introduction to HID SCI, highlighting and comparing their technical merits, as well as the benefits they offer for next-generation Bluetooth LE HID solutions.
