BLE-MIDI/src/hardware/BLEMIDI_ESP32_NimBLE.h compile error

[RCPilot1604]

Attempted to compile a previously working piece of code which now produces the following compilation error.
The error is in line 144 and 145 of Arduino-BLE-MIDI/src/hardware/BLEMIDI_ESP32_NimBLE.h.

I suspect that there was a migration of the h2zero/NimBLE-Arduino library, causing the code to break.

I can confirm I'm having the exact same problem, and when I roll back to version 2.1.0, the project compiles just fine.
