Which IDE version are you using? If you are on 1.6.8 could you try testing 1.6.7 and see if it still happens?

right, thx for your help :slight_smile:

So it's not happening in 1.6.7? If so, could you also test this build?

@facchinm

1.6.7 is right,but 1.6.8 shows 'port is busy ' or 'not available'.

the test build is same as 1.6.8. but, sometime is right,it'sstrange

sometime,after uploading,the tool>serialport don't show 101's port.

this time, reupload,IDE would display error info.

hope info is helpful.

Is this on Windows 10? I saw the same thing on a Win 10 VM with 1.6.8. I couldn't upload or even open serial monitor. 1.6.7 is fine. Even in 1.6.7, Win 10 seems sluggish in dealing with ports but it could be because I was on a VM.

Hi coloz,
could you test this build? Rework serial ports handling by facchinm · Pull Request #4792 · arduino/Arduino · GitHub
It should solve the "port busy" problem.
Remember to post here the results :wink:
Thanks
