@kuriko

Thank you so much for your help Kurikio. And for your crazy fast response. This is exactly what I needed to get myself back on the right path. I through together a quick test this morning and everything is now running smoothly and I'm able to change between different lighting setting with out the program crashing or getting stuck in a endless loop.

Here's what I ended up putting together. Three buttons on the display that could change between three preset colors and a effect pattern, the A and B buttons mirrored the first 2 button and the C button turned off the lights.

Thank again so much for your help. Here are some photo of my end result:

If you’re unable to run UIFlow or M5Burner on Windows 10, try running the app as administrator and ensure all necessary USB drivers (like CP210x or CH340) are installed. Disable antivirus temporarily, update your .NET framework, and check if the device is recognized in Device Manager. Reinstall the latest version from the official M5Stack site. Compatibility mode and checking firewall settings can also help resolve startup or connection issues.

Any updates on this @m5stack ?, does anyone know when this will be working again?

Thanks,
Marnix

UIFlow2 can feel odd due to inconsistent block behavior, limited error feedback, and occasional cloud sync issues, making it tricky for users to debug and manage projects efficiently.

The green icon likely means the device connected to flow.m5stack.com successfully, but the API key connection might need extra steps. First, ensure you entered the API key correctly in UIFlow Web. Also, check if your firewall or network settings block the device from appearing in Fritzbox. For logs, try enabling debug mode in the M5Stack settings or use serial output to inspect connection details. Sometimes, the device uses a separate network interface that Fritzbox might not show. Double-check your Wi-Fi credentials and restart both device and router.

To interrupt a loop using a button input, ensure the program continuously checks the button state within the loop. If the loop doesn't monitor inputs regularly, it may miss the button press. Use flags or conditions triggered by the button to break or exit the loop immediately when pressed.

The M5Burner DBus error when publishing a BIN file usually indicates a permissions or communication issue between the app and system services. To fix it, try running M5Burner as administrator (or with sudo on Linux), ensure DBus is properly installed, and check USB device access permissions on your system.

@felmue I was struggling to figure out why my FIRE was restarting each time I tried to use the UART port... Using Port B worked though.

Thanks for the suggestion!

@I_am_Exiled When I get situations lie that I just use M5 Burner to erase and start over

@nabstar Did you ever find a solution for this? I’m having a similar problem

Hi Liquidbeam,

I know it has been a long time since you posted this, and I am curious if you ever got it to work. While I have worked with M5Stack (Blockly) for years. I know I can help you with the other aspects of your desired application and am more than willing to assist. This however is my first experience with BLE device scanning.

I copied your code into my CoreS3 with UIFLOW2 V2.2.4, and I can't even replicate what you have done.

I would very much appreciate an update on your experience.

Thank you

You mean Emulator?
No there is not.

@robski Thanks, I figured it out.

Hello, I'm going to tell you everything I know and have tried so far.
I'm experiencing an issue with my M5 Hard devices. A few months ago, I purchased a couple of M5 Hard units for an MQTT data transmission project. I developed it in UIFlow 2, and everything worked perfectly.

Recently, I bought more M5 Hard devices to expand the project, but now I’m facing a problem: when I install the firmware and try to connect them to WiFi, they won’t connect. I have tried the following without success:

Reinstalling the USB drivers on my computer.
Resetting the device to factory settings.
Reinstalling the firmware.
Trying different WiFi networks.
Temporarily disabling the firewall and antivirus.
Using different firmware versions.
Checking the router configuration and connection parameters.
Despite all these attempts, I still cannot connect them to WiFi. I’m getting the following error:

arduino
Copiar
Editar
E (328401) wifi: sta is connecting, return error
Traceback (most recent call last):
File "<stdin>", line 19, in <module>
File "<stdin>", line 12, in setup
OSError: Wifi Internal Error
Additionally, I’m also getting this error:

nginx
Copiar
Editar
E (328338) i2c: i2c driver install error
I don’t believe this is a network issue (firewall, antivirus, etc.) because, as I mentioned earlier, I have successfully programmed and connected other devices without any issues.

I would really appreciate any suggestions or help.

UiFlow have no and will no support for microphone. Please transfer to UiFlow2

Here is how I solved this:
