M5NanoC6 Initial Setup

ESPHome
1

Hi, I may have done something stupid but I’ve just received my first M5NanoC6 and trying to get ESPhome connected and installed for it but I cannot seem to get it prepared. I have it connected OK via USB, and connected through the ESPhome Web but when I try to “Prepare for first use” I get an error that the platform is not supported.

Is this that I’ve bought a new board which is not supported?

I have posted the log below if it helps (does show this is an ESP32C6 so I expected it to be supported).

here’s my working config: GitHub - bogorad/m5stack-m5NanoC6-esphome: First attempt to create ESPHome config for M5stack NanoC6

This may be a really stupid question, but given I’ve been unable to do the “prepare for first use” I have no understanding of how you’ve loaded a configuration into eshphome to control the device.

4

Ignore my question. I finally worked out how to compile the binary and load it manually onto the device.

I’m a little slow, but getting there.

5

Could you pleas elaborate so others can accomplish this, too?

  • Build the firmware using the Manual option and download the .bin file (Factory mode)
  • Connect the device to the PC whilst holding the button (it enables as a serial port device)
  • On the ESP Home connect device screen connect to the serial port
  • Click the Install button and browse to the .bin file & click install
    when complete remove power and restart the device and it loaded the ESP firmware and connected to wifi

I to am trying to get this one going. I assume when you connect the M5NanoC6 holding the button, it should show up in device manager with a serial port. When I plug it in holding button, I do here a ding, but :

  1. Web.esphome.io does not find a port, and
  2. Looking in device manager, there is no USB port.

If I do the same thing with a normal atom lite, it all works fine with the same cable, setup and everything.

I had wondered if it was a driver problem. But because I can’t see a device in device manager that has a problem, I assume this is not the problem??

I have tried this with 2 NanoC6 with same results so assume it is not a hardware issue.

Does anyone have any ideas on what I am missing.

I realise this is not helpful to you in finding a solution, but I see that when I connect the device using a USB-C cable regardless of whether I hold the button.

Probably worth checking that the cable you are using is a data cable, or a charging only cable… can you test with any other device to see if it detects correctly to validate?

9

Turns out your reply was REALLY useful. Because with all my other ESP32, I have been using USB-A to C cables from a USB-A port, I have not tried and USB-C to USB-C cable in USB-C port. So I tried that, and I can connect via serial now!!

Next I need to figure out how to " Build the firmware using the Manual option and download the .bin file (Factory mode)" which I have not had to do before, but hopefully this is straight forward. But not I have figured out the serial connectivity, I should be able to upload the bin file.

10

Here are the steps I took:

  1. create the device in ESPhome manually and setup up all the necessary in the YAML
  2. Click the Install button (top right):

  3. choose manual download
    2025-02-02 13_23_03-ESPHome Builder – Home Assistant - Brave
  4. wait for it to compile then when prompted chose Factory Format:
    2025-02-02 13_27_15-ESPHome Builder – Home Assistant - Brave
  5. make sure your browser does not “protect you” and not save the file :wink:

I actually used the option to install it on the NanoC6 be connecting it to my HA server running ESPHome (Plug into the computer running ESPHome Device Builder), which is a VM running on Proxmox. I don’t like to send sensitive data to the internet so thought I could try this.

12

It literally says in the description no data is sent to ESPHome. It’s an entirely local process.

13

Yes. And the only way to know if that’s true or that it’s not hacked or whatever is by researching the code that is being executed. I found my chosen option to be easier and quicker.

14

You are you literally flashing their code onto your device. If they wanted to do anything malicious, that’s where it’s gonna happen.

15

Fair point. I was thinking more of external hackers etc as a danger but that could also happen with the code I flash.

Hello is your yaml still able to compile with a c6 lately? I cant for the life of me get it to work. I managed to get it to work using this yaml but the logger does not work.

Using esphome standalone it compiles fine though.

Okay so after speaking on the discord the error I was getting above can happen sometimes “That missing package thing is a platformio problem that has been happening a lot lately. Try re-installing the add-on.” not sure if that would resolve it for myself because now I prefer to use the cli version of esphome.

For anyone struggling to get the nano c6 to work try the cli version, it compiles fine for me there, then gets picked up in HA just have to enter the encryption key.

21

Actually I had a different problem. Nothing but docker version complied ok for quite some time, so I gave up on any other version :slight_smile:
