BLE MIDI Client, ESP32-S3, keeps sending serial when not connected

[jhsa]

I am trying to make an BLE MIDI to USB Midi and Serial midi adapter. Everything works, but when it disconnects, the ESP32-S3 starts sending something on the serial pin, until it connects again. Is this a bug? Is it possible to disable this serial in the library? Thanks

#include <Arduino.h>
#include <MIDI.h>
#include <Adafruit_TinyUSB.h>
#include <BLEMIDI_Transport.h>
#include <hardware/BLEMIDI_Client_ESP32.h>

BLEMIDI_CREATE_DEFAULT_INSTANCE(); //Connect to first server found
MIDI_CREATE_INSTANCE(HardwareSerial, Serial,  MidiSerial);

// USB MIDI object
Adafruit_USBD_MIDI usb_midi;

// Create a new instance of the Arduino MIDI Library,
// and attach usb_midi as the transport.
MIDI_CREATE_INSTANCE(Adafruit_USBD_MIDI, usb_midi, MidiUsb);

int Led = 42; //modify for match with yout board

bool isConnected = false;

void setup()
{

  BLEMIDI.setHandleConnected([]()
  {
    Serial.println("---------CONNECTED---------");
    isConnected = true;
    digitalWrite(Led, HIGH);
  });

  BLEMIDI.setHandleDisconnected([]()
  {
    Serial.println("---------NOT CONNECTED---------");
    isConnected = false;
    digitalWrite(Led, LOW);

  });

  pinMode(Led, OUTPUT);
  digitalWrite(Led, LOW);

   TinyUSBDevice.setManufacturerDescriptor("My_Manufacturer");
  TinyUSBDevice.setProductDescriptor("BLE_USB_Aapter");

  // Initialize MIDI, and listen to all MIDI channels
  // This will also call usb_midi's begin()
  MidiUsb.begin(MIDI_CHANNEL_OMNI);

  MIDI.begin(MIDI_CHANNEL_OMNI);
  MidiSerial.begin(MIDI_CHANNEL_OMNI);

  MidiSerial.turnThruOff();
  MIDI.turnThruOff();
  MidiUsb.turnThruOff();
}

void loop()
{
  if (MidiSerial.read()) {

    MIDI.send(MidiSerial.getType(),
              MidiSerial.getData1(),
              MidiSerial.getData2(),
              MidiSerial.getChannel());

    MidiUsb.send(MidiSerial.getType(),
                 MidiSerial.getData1(),
                 MidiSerial.getData2(),
                 MidiSerial.getChannel());
  }
  if (MIDI.read()) {

   if(isConnected) {
    MidiSerial.send(MIDI.getType(),
                    MIDI.getData1(),
                    MIDI.getData2(),
                    MIDI.getChannel());
   }

    MidiUsb.send(MIDI.getType(),
                 MIDI.getData1(),
                 MIDI.getData2(),
                 MIDI.getChannel());
  }

  if (MidiUsb.read()) {
    MIDI.send(MidiUsb.getType(),
              MidiUsb.getData1(),
              MidiUsb.getData2(),
              MidiUsb.getChannel());

 if(isConnected) {
    MidiSerial.send(MidiUsb.getType(),
                    MidiUsb.getData1(),
                    MidiUsb.getData2(),
                    MidiUsb.getChannel());

  }
   }
}

Solved, commented all Serial Prints in "BLEMIDI_Client_ESP32.h"

a classic error :-) (still happens to me once in a while)

As a beginner, I am a little afraid of editing the libraries. Isn't that a way of moving all those serial lines to the examples themselves? I think that all the mods I did will be erased next time I update the library, right?

your code sits aside from the library, so nothing will be reset next time you update. Unless you made changes to the library code itself

Yes, that is what I meant. As I said above, commented all Serial Prints in "BLEMIDI_Client_ESP32.h", and of course also, no serial stuff on my code as well.
