Mezzz Firmware Update Troubleshooting

Mezzz
1

Hi

I’m trying to update mezzz, but [cu.usbmodemXXXXX port,] doesn’t appear.

Instead, “cu.Bluetooth-Incoming-Port” will appear.

I am using the USB that came with the Mezzz when I purchased it.

However, there are third-party adapters available to convert to USB-C.

I’m using a Mac Book Air M2.

▼Troubleshooting steps taken

I tried everything, but only “cu.Bluetooth-Incoming-Port” still appears.

Troubleshooting

Serial port never shows up? Try activating Programming Mode

Hold the center button while turning the device off and then on to place Mezzz into Programming Mode. No leds will light up in this mode but the port will be visible.

Can’t connect to serial port?

Make sure other programs aren’t trying to use the port, including any IDE, browser, game engine, vj software etc.

Hey! perhaps you could give us some more specific info here…

What happened when you took these steps?

Where you able to enter programming mode?

Are you using Chrome browser?

I am also unclear if youre using this cable directly or using an adapter on one end for USB-A to USB-C, if so please try to verify that the adapter has working data lines with another device. Please describe your wiring in more detail.

Hi, I’m having a similar issue. It seems like the updater tool is recognizing the Mezzz similar to the poster above, and that the Mezzz is successfully updated. However, after doing so, mine won:t turn light up when turned on, seems like it’s stuck in programming mode or something. I can see the USB light turn on when I plug the USB in.

Here’s details on what I did:
Plugged usb into Mac via adapter.
Selected the recognized device.
After it connected, selected the 1.4 firmware bin and ran the program.
After running through 100% write, the program says Leaving…
Turned off mezzz, turn back on but no LEDs

Did the same thing on my PC but without the usb adapter.

Did you use chrome? did you use the supplied cable? did you make sure to flash to address 0x000?

Hey there,
at a point, the updater tool broke, so we found another.

but use this one: Adafruit ESPTool

and run mezzz in programming mode, from there you should be able to reset it and keep it going with the new firmware.

Hey, thanks to both of you for taking the time to respond! I did indeed figure this out, complete user error! I thought my Mezz and Hypno would be completely up to date being brand new, but it seemed that they had some older firmware installed and weren’t speaking. All is good now, and they both rock!
