What could be causing intermittent UART communication failures in my AVR32UC MCU running Zephyr OS?
I'm trying to develop a smart healthcare system using an AVR32UC microcontroller running Zephyr OS. The system uses UART to communicate between the MCU and a central monitoring station. However, I'm experiencing intermittent communication failures, where the data received is occasionally corrupted or incomplete. I suspect the issue might be related to my UART configuration or the Zephyr OS UART driver. I have Verified the baud rate and ensured it's the same on both ends, checked for noise issues on the UART lines, and experimented with different buffer sizes. What could be causing the intermittent UART communication failures? Are there any specific configurations in Zephyr OS that I might be missing to ensure stable UART communication?

Solution
If you dealing with intermittent UART communication issues on a AVR32UC microcontroller running Zephyr OS , you must check your UART setup .
Your hardware flow control should be enabled, adjust the buffer sizes, ensure the ISR is running smoothly
