B4J Question Serial Port Close

[mrossen]

Hi,

When I close the Serial Port this been written in the log?

Anyone know why?

Program started.

Have you closed AsyncStreams before closing the serial port?

 

[mrossen]

No,

I have done that now and now I only got it once,

Program started.

Can you upload your project (File - Export as zip)?

 

[mrossen]

Yes,

The test is based on your chat,

 

[Erel]

Does your program crash? Or you only see this message in the logs? If it doesn't crash then you can ignore it.

 

[mrossen]

No crash, I only see it in the log.
