Is there way to immediately initiate sending data through the uart once a uart.Write command is sent? I’ve tried using uart.Flush() but that does not appear to have any effect. Thank you.
UART data is sent immediately. It is a few ms to get the process going but I do not believe hold TX data. Are you seeing something different? Maybe your receiving end is buffering the data?
How did you know it does not have any effect?
if it stays long or not send at all mean wrong somewhere else.
Thanks for the replies. I got a hold of a scope and realized it was my issue. Uart.Write is working as expected.

What was the issue? Was it plugged in?
Forgot to take out a 500ms delay that I was using for troubleshooting another issue.
