Specialized Mission Control App Details & Settings

As long

As long as your Creo is non-Mastermind TCU version, BLEvo is far superior to the MC.
Sad to say, I do have a Mastermind TCU. I found a discussion that confirms what you imply, that BLEvo is not compatible with Mastermind TCU, and it probably never will be:

Apparently the reason is encryptions added to the Bluetooth protocol due to regulatory concerns. I can sort of understand that, but the fact that Spec's own limited app doesn't even work as advertised just adds insult to the injury of losing BLEvo.
