post your code will be more helpful

Hi @Gaviota.
Currently I'm still learning to use UI Flow IDE and I want to crate the same thing- counting pulses and showing them on the screen. Can you send me your Blocky?
Thanks,
Bozho

great job!

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.
