Cannot receive large Sysex from NUX MG-30 #725

karozas · 2022-07-04T16:22:27Z

Hello from Greece.I am trying to build a MIDI contoller for NUX MG-30 (guitar multieffect unit). I send this sysex message
F0 43 58 70 0A 00 F7 in order the NUX MG-30 to respond with a 218 bytes long sysex that contains the data of the current patch . The NUX MG-30 is recognised by the usb host , I can send PC or CC messages to the NUX MG-30 or other sysex messages and the device responds normally but does not when I send the above sysex.This is what I get when I run MIDI_USB_desc sketch :

Thanks for the response.I will check it.

karozas · 2022-07-04T23:05:54Z

I 've loaded this example sketch :

`
#include <usbh_midi.h>
#include <usbhub.h>

// Satisfy the IDE, which needs to see the include statment in the ino too.
#ifdef dobogusinclude
#include <spi4teensy3.h>
#endif
#include <SPI.h>

#define _MIDI_SERIAL_PORT Serial

uint8_t reqpatch_NUMBER[] {
0xf0, 0x43, 0x58, 0x70, 0x15, 0x00, 0xf7
};

uint8_t reqpatch_DATA[] {
0xF0, 0x43, 0x58, 0x70, 0x0A, 0x00, 0xF7
};

USB Usb;
USBH_MIDI Midi(&Usb);
uint8_t phase = 0;

void setup()
{
_MIDI_SERIAL_PORT.begin(115200);

//Workaround for non UHS2.0 Shield
pinMode(7, OUTPUT);
digitalWrite(7, HIGH);

if (Usb.Init() == -1) {
  while (1); //halt
}//if (Usb.Init() == -1...
delay( 200 );

}

void loop()
{
Usb.Task();
if ( Midi ) {
MIDI_poll();
if ( phase == 0 ) {
_MIDI_SERIAL_PORT.println("\nRequest: reqpatch_NUMBER");
Midi.SendSysEx(reqpatch_NUMBER, sizeof(reqpatch_NUMBER));
phase++;
delay(10);
} else if ( phase == 1 ) {
_MIDI_SERIAL_PORT.println("\nRequest: reqpatch_DATA");
Midi.SendSysEx(reqpatch_DATA, sizeof(reqpatch_DATA));
phase++;
delay(10);
}
}
}

// Poll USB MIDI Controler
void MIDI_poll()
{
uint8_t size;
uint8_t outBuf[4];
uint8_t sysexBuf[3];
char buf[20];

do {
  if ( (size = Midi.RecvRawData(outBuf)) > 0 ) {
    uint8_t rc = Midi.extractSysExData(outBuf, sysexBuf);
    if ( rc != 0 ) {
      //SysEx
      _MIDI_SERIAL_PORT.print("SysEx:");
      for (int i = 0; i < rc; i++) {
        sprintf(buf, " %02X", sysexBuf[i]);
        _MIDI_SERIAL_PORT.print(buf);
      }

    } else {
      _MIDI_SERIAL_PORT.print("_____:");
      for (int i = 1; i <= size; i++) {
        sprintf(buf, " %02X", outBuf[i]);
        _MIDI_SERIAL_PORT.print(buf);
      }
    }
    _MIDI_SERIAL_PORT.println();
  }
} while (size > 0);

}`

and I get this in serial monitor:

Request: reqpatch_NUMBER
SysEx: F0 43 58
SysEx: 70 15 02
SysEx: 01 03 64
SysEx: 00 00 00
SysEx: 00 00 F7

Request: reqpatch_DATA

When its sending reqpatch_DATA sysex I get nothing but for example with zoom ms50g it works flawlessly (with another sketch of course).

karozas · 2022-07-08T06:10:34Z

sorry I closed this case by mistake.Anyway I 've loaded the above example sketch and I got this in serial monitor:

Request: reqpatch_NUMBER

SysEx: 70 15 02
SysEx: 01 03 64
SysEx: 00 00 00

Request: reqpatch_DATA

the response in reqpatch_DATA should be something like this :

but I get nothing .I ve used ARUINO MEGA and UNO with usb host shield and the results are the same.When I use serial MIDI and Raspberry pi as a usb host the device I built works fine.Thank you again and sorry for closing the issue by mistake.

YuuichiAkagawa · 2022-07-08T12:52:59Z

Run with debugging enabled.
https://github.com/felis/USB_Host_Shield_2.0#enable-debugging

My concern is that the endpoint size is larger than 64 bytes.
Full speed should be 64 bytes, but MG-30 reports 512 bytes.
MAX3421E and USB Host Shiled Library support only up to 64 bytes.
If the MG-30 is sending 218 bytes at a time, this cannot be received.

0x0F : hrBABBLE : Device talked too long

We suspect that the MG-30 is transmitting more than 64 bytes of data at a time.
Unfortunately, it is not supported by USB Host Shield.
You must select a microcontroller that supports USB 2.0 Hi-Speed. For example, Teensy 3.6/4.1.

karozas · 2022-07-09T05:11:07Z

I see!Thank you very much for your help.I will try a Teensy 3.6/4.1 when I have time.
