Invalid argument(s): length must be in the range [0, 4611..]

It does not show this error all the time, but when it does, the communication can not be established by this port again. But, turning it off and on manually fixes the problem. However, we can not count that as a constant solution for this problem. Is there any other way we can follow to solve it automatically? (without turn the port on and off MANUALLY)

Same here, have you found a solution?

sp_nonblocking_read may return negtive value on error. This library assume that read operation is always success. If the return value is negative, asTypedList may throw that exception.

You can use sp_last_error_message to check what error occured.

How do I call sp_last_error_message when I'm using flutter_libserialport and not libserialport?

Could anyone check this one as 0.4.0 is available on pub.dev?

@lucafabbri Am currently on 0.4.0 but am facing the same issue

[MironRobert]

Has anyone found something about this issue? I have the same issue but not at the same place. Because for me, it happens only when I manually turn it OFF and ON.

The only thing I know is that, just disconnecting the port gets an "errno = 5" (and can sometimes crash the app). Yet reconnection automatically gets "errno = 0".

But to get that i just printed ("SerialPort.lastError") and the Unhandled exception wasn't there anymore. Just the errors listed before.

And i just don't understand why at some point the errno = 5 crashes my app.

I'm in 0.4.0.

I am also on version 0.4.0 and facing the same problem, any solution to this?
