Google your UUIDs

When reverse engineering a device, it is often times handy to Google any UUIDs you might find.

In my case, I otherwise would not have noticed that Antti works at OURA, because a github issue was posted with an OURA Bluetooth UUID(98ED0001-A541-11E4-B6A0-0002A5D5C51B) that is only present in the OURA APP and AES encrypted ring firmware.

In my particular case, this corroborates my suspicion that the following UUIDs:

• 98ED0001-A541-11E4-B6A0-0002A5D5C51B
• 98ED0002-A541-11E4-B6A0-0002A5D5C51B
• 98ED0003-A541-11E4-B6A0-0002A5D5C51B

belong to the OURA's bluetooth communications subsystem. This is trivial to prove if one owns an OURA, but as I do not, the github issue suffices.
