Hi,

This is not easy to describe:
I'm using "port.datareceived += dataReceived" to start processing an incoming data stream from a serial port.
When I want to stop that, I use the "-=" and it works. Problem is that it seems to take some time and that theres is at least one more data sample going through which causes an error due to the processing.

I put a "thread.sleep(500)" behind "port.datareceived -= dataReceived"
But it didn't help.

This also seems to be a windows processing problem, because in some cases it works fine and in some it doesn't.

I hope this makes sense to anyone.

Thanks in advance,

Mike

Solution 1

I would try closing the serial port, removing the handler, and the opening the port again.

Solution 2

I would recommand you to use a background thread for all communications including opening and closing serial port if you want to avoid blocking delays in your UI.
