Chrome and Chrome OS have a lot of internal URLs starting with chrome:// providing an ocean of information about your Chromebook and browser. Chrome OS is getting a new page, chrome://bluetooth-internals for Bluetooth.
This page is currently available in Chrome OS Canary channel and can show status, services, characteristics, and soon, descriptors. If you use Bluetooth devices with your Chromebook this will be a good resource for you to know more about these device connections and also to debug when you are unable to connect to any Bluetooth device.
If you are a developer looking for more information about this page, find the details here.
