Well, for the first time in ever… I can say I have a spare ESP32 
and thus was able to give this a try.
I simply loaded in the base sketch from the GitHub link above and added in some existing code for a physical RGB LED
It showed up as Blynk and didn’t want to connect on my older Samsung Note8 tablet… so far… but connected right away on my LG G6 
Latest ESP32 core (do they even have version numbers? If so, where?)
Blynk 0.5.2
ESP32 DEVKIT (no name clone?) (Chip rev1)
Android 7.0
App 2.20.1
Local Server (if that matters)
The ESP32/Blynk BLE link is WORLDS stabler than my old LightBlueBean… I think I might bury it (the LBB, not the ESP 
) and see what kind of a beanstalk grows from it
