stucked with sysex

[eqcq]

Hi,

a midi device I've made, receive and read sysex message with this function :

void OnMidiSysEx(byte* pData, unsigned length) {
  std::string myString((char*)pData, length);
  String message = myString.c_str();
  ChaineMemoire = message;
}

Everything is ok with ios app I've developped to send message to my device

now I wanted to send sysex with another device I made using this code :

#include <MIDI.h>
MIDI_CREATE_DEFAULT_INSTANCE();

void sendsysex() {
   uint8_t sysex[] = {0xF0, 0x65, 0x73, 0x73, 0x61, 0x69, 0x0A, 0xF7};
   MIDI.sendSysEx(8, sysex, false);
}

void setup() {
  MIDI.begin();
  // put your setup code here, to run once:
}

void loop() {
  sendsysex();
  delay(5000);
}

and the message don't seems to be received. what do I do wrong ?
THX !

Your message does contain the SysEx boundaries (0xF0 and 0xF7), so you'll need to pass true to the last argument of sendSysEx:

void sendsysex() {
   uint8_t sysex[] = {0xF0, 0x65, 0x73, 0x73, 0x61, 0x69, 0x0A, 0xF7};
   MIDI.sendSysEx(8, sysex, true);
}

Could you use a MIDI monitor to inspect what is sent by the iOS app (and understood by your receiving device), and what is sent by your emitting device, and find the difference?
