KICKR GATT Profile - StephenDone/kickr_bluetooth GitHub Wiki
Bluetooth standard UUIDs are all based around the Bluetooth Base UUID of xxxxxxxx-0000-1000-8000-00805F9B34FB.
In a similar way, the Wahoo UUIDs that I have seen so far have a base of a026xxxx-0a7d-4ab3-97fa-f1500f9feb8b.
This is anecdotal, but holds true for me so far.
BLE Advertisement
Very sensibly, the KICKR Bike advertises its most important services.

Note that in the table below, the names I have come up with for the Wahoo services are my own, since they are not documented, to my knowledge.

BLE Service Dump using Python Script
This is a little more raw than the information above, but shows the handles too. I guess these may change with firmware updates though...
