Boolean operators turn undefined


#1

Hi all, as a relative novice to Makeblock, Scratch etc., I stumbled on a problem I’m not able to solve. (And which is very annoying…)

Since recently, all my Boolean operators turn into ‘undefined’ after restarting mBlock. First happened with quite an elaborate programme. Then tested it in a very short test.

When the bot is connected it works fine. I’m also able to upload the Arduino and run this autonomous.

But if I close mBlock and restart the file it looks like this…

I work only in scratch mode, not mastered Arduino yet. Windows 10, mBlock 3.4.3. mBot Ranger Auriga board. (But none of these parameters changed recently and everything worked fine before).

What’s going on?

PS Sometimes mBlock crashes all together…

You can download the software and reinstall, we fixed the bug, but we don’t change the version number because the timeline about release the version
