Error compiling for board Adafruit Bluefruit Feather nRF52840 Express.

Steps to reproduce the problem

Select board as Adafruit Bluefruit Feather nRF52840 Express. Add "#include <MIDI_Controller.h>" to the code.

Hardware

Adafruit Bluefruit Feather nRF52840 Express

Software versions:

MIDI Controller library: 3.1.1
Arduino IDE: 1.8.9
Operating System: Lubuntu
MIDIUSB library: 1.0.4 (also doesn't support this board)

Steps taken to try to diagnose or solve the problem

? Tried the MIDI debug mode, used a MIDI monitor, ... ?

The goal of your project and aditional information

Make usb midi controller that can also receive midi over bluetooth

[tttapa]

This board is not supported, and I have no plans to add support for it.

The updated version of this library, Control Surface, does have experimental MIDI over BLE support, but only on ESP32 boards.

You can reuse the BLE MIDI parser, but you'll have to implement your own functions to receive and send Bluetooth packets.
