ESP32-S3 DevC-1-N16R8-S3 not works (SOLUTION !!!)

[bruxotolo]

Hello. I have an M-vave MidiA (MIDI-Bluetooth adapter) connected to my Line 6 Helix, which allows me to send MIDI messages via Bluetooth that my Waveshare 4.3B touchscreen receives perfectly and uses to change presets on the ToneX One.
I have purchased an ESP32-S3 DevC-1-N16R8-S3 and used the corresponding firmware from the installer to install version V2.0.3.2 with the ESP DEVKitC N16R8, successfully connecting to the M-vave MidiA (adding it in the web configurator) as the blue LED on the MidiA stays lit, indicating that it has connected. I’m trying the same setup on my Helix, and every time I use a Helix footswitch, it should change the preset on the ToneX One, but it doesn’t. However, it does receive the signal because a blue LED on the ESP32-S3 lights up briefly when I do so, but the ToneX One doesn’t change the preset.
Can you help me?
I’d also really appreciate it if you could add the circuit to the project for making a bridge to connect to the controller via a DIN5 cable. I know they’re sold, but they’re not easy to come by here, and I think there are very few components needed for a DIY project.

Thanks a lot.

Hi. On the DevKic-C, do you have Midi enabled on it? And Midi CC enabled? I'm not quite understanding your setup. If these settings don't help, please explain some more about what data you are sending (PC, CC, what Midi channel etc.)

You can find the schematic for the Midi featherwing here:

I’m currently setting up MIDI message transmission from my Helix via Bluetooth (using the M-Wave MidiA adapter). It works perfectly with version 4.3B, but with the S32-S3 DevC-1 N16R8 it doesn’t work with the same Bluetooth settings. Although, as I said, when I press the footswitch on the Helix, an LED on the DevC-1 does light up momentarily, which means it is receiving something.
I ran this test via Bluetooth because I’ve built the Din5 adapter and saw that it wasn’t working, and I wanted to rule out the possibility that it was faulty (I know that with that adapter I need to enable wired MIDI).
The images show the settings on both Helix and the board

Thanks a lot.

Hello again.
I’ve carried on testing, even with another DevC-1 board, and it’s still the same, but I’ve realised that the fault isn’t whether or not the board is receiving the MIDI signal (which it seems to be, as the LED flashes once when I press the Helix switch); the problem is that the board isn’t connecting to the Tonex One because when I go to 192.168.4.1 and look under Config ---> Preset Map, it shows nothing.
When I use the 4.3B version, which I mentioned worked, and look under Config ---> Preset Map, it shows me all the presets on my Tonex.

Could there be a firmware issue with the Esp S32-S3 DevC-1 N16R8 board?

I tried both firmware versions and the same thing happens.

Thanks.

The solution is to connect these two points with a bit of solder. This allows current to flow through the USB port and enables the Tonex One to detect the host. It can also be powered from the board (I’ll check if this is stable; if not, I’ll connect the Tonex One to its 9V power supply).

Hi. I have this documented here:
