Doesnt works after some time

[adarshdevadiga]

hello , this library stops working after some time (like about 2 min)
actually im using it in raspberry pi to read multiple serial data via usb ports. it works properly for first 2 minutes, but stops working ( not reading afterwards) . any solution?

[SunitRaut]

In our tests, the library does work beyond 2 minutes. Do you get any error messages after 2 minutes?
It would be helpful if you share your Python code with us. Also, you can share your Arduino code so we can replicate & check the issue on our end.
