Looks great. Awesome to set the list of supported Bluetooth Health services grow 🚀 I really only had comments regarding some minor documentations improvements. Everything else looks fantastic 👍

Generally, you might want to add these new types to the SpeziBluetoothServices.docc bundle and group them into fitting topics sections similar to the existing ones. What I like to do, is to Build Documentation locally in Xcode and look at which types are not grouped/structured yet. We currently have articles pages for Characteristics and Services to provide a good overview of all supported services and characteristics of SpeziBluetooth.
