End of frame will also generate tout interrupt so unless you need ultra realtime processing of messages it should be ok.

We didn't set fifo threshold to 1 byte but set 1 byte as interrupt to get each byte interrupt.

Isn't that the same thing?

uint8_t rxfifo_full_thresh
UART RX full interrupt threshold.


Why do you need an interrupt for each byte? Default is 120.

Spring festival can start before some 3.0-final release or 3.1-rc release? :(

That will use heap memory so print your free heap and check for memory leak
