When we are using TX and RX, I want to know how RST will behave?
Hi nicksj.lin,
Are you using the devkit or custom board for Orin NX?
What’s your Jetpack version in use?
If you use TX/RX only for UART, please just disable HW flow control in your application before use.
This is not something easily answered, but I will suggest that my experience is that CTS/RTS is more reliable than no flow control. Theory says they are no different, but in order for a UART signal to work, there is some maximum amount of jitter allowed. The faster the speed, the less lenient one can be with jitter. CTS/RTS can improve start and stop timing. Then again, it might not do anything if the signal jitter is already ok. CTS/RTS also helps preventing any kind of buffer overrun since the sender won’t send if the receiver says “no”.
