Channel Sounding CR_PR Draft

The Channel Sounding and Channel Sounding HCI Updates documents together specify the changes to the Bluetooth Core Specification required to add the Channel Sounding feature, which specifies methods and provides information for estimating the distance between two Bluetooth Low Energy devices. 

The Bluetooth Core Specification, Version 5.4, can be downloaded for additional context at the Core Specification 5.4 landing page. Each section title in the Channel Sounding CR and the Channel Sounding HCI Updates CR references the number and title of the section being added or modified in the Bluetooth Core Specification. Conventions that distinguish the proposed changes from the current adoption are described in Section 2 of each CR.
