Hola, gracias por tan fabulosa libreria.
Bien, sere breve, me preguntaba si se pueden crear varias sesiones en el es32 via wifi, asi como se crean via ethernet

APPLEMIDI_CREATE_INSTANCE (EthernetUDP, MIDI1, " Arduino1 " , DEFAULT_CONTROL_PORT);
APPLEMIDI_CREATE_INSTANCE (EthernetUDP, MIDI2, " Arduino2 " , DEFAULT_CONTROL_PORT + 2 );

Pero no se si se pueda, y que habria que colocar en lugar de EthernetUDP.

Muchas gracias, un saludo

Hola @Veroledez. At first glace nothing wrong with your code, good job!

I copied into the Arduino IDE and compiled for ESP32 DevKit, tweaked the code left and right (kept the essentials) and got good results. Can you try the below.

I noticed you did not show the IP address - how did you know the IP address of the ESP32? (Bonjour is not enabled in the code below)

In any case, try the below:

#include <WiFi.h>
#include <WiFiClient.h>
#include <WiFiUdp.h>

#define SerialMon Serial
#define APPLEMIDI_DEBUG SerialMon
#include <AppleMIDI.h>

char ssid[] = "xxx"; // your network SSID (name)
char pass[] = "yyy"; // your network password (use for WPA, or use as key for WEP)

unsigned long t0 = milli…

Hola @Veroledez

Taken from the ESP32_wifi example and

Arduino-AppleMIDI-Library/src/AppleMIDI.h

Lines 350 to 352 in 7c96535

 #if defined(ARDUINO_ARCH_ESP32) || defined(ESP32) 

 #define APPLEMIDI_CREATE_DEFAULTSESSION_INSTANCE() \ 

 APPLEMIDI_CREATE_INSTANCE(WiFiUDP, MIDI, "AppleMIDI-ESP32", DEFAULT_CONTROL_PORT);

Your code could something like this:

#include <WiFi.h>
#include <WiFiClient.h>
#include <WiFiUdp.h>

APPLEMIDI_CREATE_INSTANCE(WiFiUDP, MIDI1, "AppleMIDI-ESP32-1", DEFAULT_CONTROL_PORT);
APPLEMIDI_CREATE_INSTANCE(WiFiUDP, MIDI2, "AppleMIDI-ESP32-2", DEFAULT_CONTROL_PORT+2);

Let me know if this works

Hola, lo he probado y en el rtp midi no se anuncia el esp32, cuando uso solo el ejemplo de una instancia si se anuncia

Can you post minimalist code, so i can try to replicate

Hola, aqui esta mi codigo completo, soy un novato en esto por lo que algunas lineas que tiraban error al compilar y como no se que poner alli las he comentado, y aunque compila y sube al esp32 no hay forma de conectarse a la sesion. Lo ejecuto en windows 10, con rtpmidi y fl studio, el ejemplo predeterminado de la libreria si me funciona
Agradesco mucho tu ayuda, un saludo
