Build Error MIDI over BLE

diggyvee · April 9, 2025, 2:48pm

Hi, have been fiddling with Arduino for a little while and decided to have a look at BLE and specifically MIDI over BLE.

Have a really simple project which loads:

#include <ArduinoBLE.h>
#include <BLEMIDI_Transport.h>
#include <hardware/BLEMIDI_ArduinoBLE.h>

using the BLE-MIDI library fromn lathoub.

When I try to complile it though I get the following errors:

In that library file those are defined as such

const char *const SERVICE_UUID        = "03b80e5a-ede8-4b33-a751-6ce34ec4c700";
const char *const CHARACTERISTIC_UUID = "7772e5db-3868-4112-a1a9-f2669d106bf3";

This is the contents of "Copy Error Message" if it helps further

I am unsure what they should be at this point, if anyone has any pointers I would be very grateful.

First, edit your post and add code tags to both the source code, and a verbose error log.

diggyvee · April 9, 2025, 3:31pm

Hi,

OK have done that, i think.

Cheers

Ian

sonofcy · April 9, 2025, 3:44pm

You still need to post the entire sketch. We need that so we can try to do a compile. I will make a guess that you have not installed a library, but post the code so we can try.

sonofcy · April 9, 2025, 3:46pm

Correction, all libraries are installed, it's just as the error says, missing needed constants as the error msg states.

sonofcy · April 9, 2025, 3:51pm

IDGI, it fails differently for me.

sonofcy · April 9, 2025, 3:56pm

Show me what board you have selected. Here is mine. Make sure your Boards Manager looks like the 2nd pic.

diggyvee · April 10, 2025, 8:03am

HI,

Thanks for this, here is the sketch in full - its a test right now, just to get an analog and digital be recodnised and pushed over BLE:

#include <ArduinoBLE.h>
#include <BLEMIDI_Transport.h>
#include <hardware/BLEMIDI_ArduinoBLE.h>

BLEMIDI_CREATE_INSTANCE("MidiManV1", MIDI)

const int btnPin = 20;
const int potPin = 5;
const int potPin2 = 6;

int midiNote;
int btnState;
int lastBtnState;
int velocity;

void setup() {
  // put your setup code here, to run once:
  pinMode(btnPin, INPUT_PULLUP);

  pinMode(LED_BUILTIN, OUTPUT);
  digitalWrite(LED_BUILTIN, LOW); 
  
  BLEMIDI.setHandleConnected(onConnected);
  BLEMIDI.setHandleDisconnected(onDisconnected);

  MIDI.begin();

}

void loop() {
  // put your main code here, to run repeatedly:
  lastBtnState = btnState;
  btnState = digitalRead(btnPin);
  velocity = map(analogRead(potPin2), 0, 4095, 0, 127);
  
  if(lastBtnState == 1 && btnState == 0){
    midiNote = map(analogRead(potPin), 0, 4095, 60, 80);
    MIDI.sendNoteOn(midiNote, velocity, 1);
  }

  else if(lastBtnState == 0 && btnState == 1){
    MIDI.sendNoteOff(midiNote, 0, 1);
  }

}

void onConnected() {
  digitalWrite(LED_BUILTIN, HIGH);
}
void onDisconnected() {
  digitalWrite(LED_BUILTIN, LOW);
}

Board selected is Arduino Nano 33 BLE as per your screenshot above, here is mine:

The fail I get is within the library file build. The constants are defined - or seem to be as per original message.

really appreciate the help.

Cheers

Ian

sonofcy · April 10, 2025, 12:15pm

I tried one of the libraries sample sketches with the NANO and it fails. Note the reference to ESP32.
It appears there is a conflict (totally normal) between one or more of you're libraries and the board chosen.
My suggestion is to divide and conquer. If you KNOW you must use a specific board, start with the examples for that board. I just looked and there is NOT much there if anything. See attached screen shot.
IF you know the sketch you want to create NEEDS a certain library, check the samples under that library (see 2nd attached screen shot)
I have not found any combination that works other than using an esp32 board.

diggyvee · April 10, 2025, 12:28pm

OK Thank you.

I was trying to shortcut a little - and had even more library conflict problems running on an ESP32 board

I'll probably just bite the bullet and write it from scratch.

thanks for all your help.

diggyvee · April 10, 2025, 12:38pm

I actually had a mad idea - if its not finding those definitions, then why not duplicate the file that's missing them (I know its bad practice) but I did and its compiled and running on the nano 33 BLE!
