Hi everyone,

i just would like to know know the sequence of reintializing UART port to a new baudarte or change parity on the go during execution.  I am using Hal library. What would be the sequence to do so and does it take long time to reintialize. If anyone can provide an example of changing baud rate would be great!. Many thanks

Sounds like it has got a framing error from receiving data at the wrong/mixed baud rate. Check the SR signalling error states, and read the DR to clear them.
