When Arduino is unplugged from USB by a bad cable or bad PC plug, adrgw.exe crashes #2

Closed RoCorbera closed 4 years ago

OS: Windows 10 Device: Arduino

Issue: when USB cable has a problem, or USB plug on PC is loose and Arduino gets unplugged and replugged to USB, AND a Scratch 3 Block is pressed, ardgw.exe crashes with this message:

Since ardgw successfully detected the Arduino, indicated in the number of pins message, I am assuming that the crash happens sometime after that. If the serial connection is broken after the board is detected, especially an intermittent connection, there is no easy way to recover.

RoCorbera commented 4 years ago

Yes, it's related to intermittent connection. This issue happens when I had about 15 PCs connected to 15 Arduino in a classroom with 30 kids. It was sort of hard to keep moving forward...

MrYsLab commented 4 years ago

Again, I understand that is very frustrating. I also understand trying to get additional funds from a school to buy or replace the cables with high-quality cables can also be an exercise in frustration.

That being said, the best I can do at this time is to refer you to the answer I provided in issue #3.

Explaining and emphasizing the startup and recovery procedure to the students may help to make things less chaotic.
