Data overflow ? #4

Closed PaulCerna closed 1 year ago

PaulCerna commented 3 years ago

Hello, thanks for this project, it helped me going on my project where I need USB to UART bridge. One issue I found - when I put a physical loopback on the UART, send a byte buffer of some 100 bytes or so, I receive less bytes back on the USB CDC device. I have now tried the sending in Windows in Python script, and on a dedicated device with native C++ code - in both cases this loopback test looses data. While I dive into the troubleshooting, do you have any advice on what might be causing this ? Thanks, Paul.

Closing this issue, as I couldn't reproduce it with latest release (https://github.com/Noltari/pico-uart-bridge/releases/tag/v4.0).
