Microblocks locks up if other microcontroller connected to USB port

[Simon Walters]

I’m running a device programmed with Arduino IDE and microblocks seems to lock up when I run it at same time

I’m on Windows 11

What's the sequence that causes the lockup?

For example, is it that the MicroBlocks stand-alone app is running but hangs as soon as you plug in your Arduino device? Or do you use the Arduino IDE to install code on the device while MicroBlocks is connected to the device? Or is it some other scenario?

Also, what kind of board is it? Does it happen only with the stand-alone app or also when you try to connect from the web app?

MicroBlocks stand-alone apps try to automatically connect to serial devices. They are supposed to give up if the device does not respond to the MicroBlocks ping message but that process may be going wrong.

Current setup is one ESP32 running Arduino code (And its outputting serial debug info)

I launch microblocks and I get varying unresponsiveness behaviour This is what happened last time - complete white screen - when I press on X, windows warns that program is unresponsive [image: image.png]

If I open microblocks without the ESP32 plugged in - everything fine

That's helpful. I will try to reproduce.

The latest pilot (1.2.45) addresses this issue. Let me know if it doesn't work for you.

Seems fixed for me as well :)

Great! Thanks for the quick testing!
