Thanks for your help

I tried to simplify the code, see below, but again it works perfectly on the WROOM board and there's no message coming from the S3 #include <MIDI.h> #include <HardwareSerial.h> #include <esp_now.h> MIDI_CREATE_INSTANCE(HardwareSerial, Serial2, midi2) void setup() { Serial2.begin(31250); midi2.begin(...
