Thanks for the info it worked, I am getting an interrupt after 8 us approx for each byte recieved. For future reference I added this to my code uart_intr_config_t uart_intr = { .intr_enable_mask = UART_RXFIFO_FULL_INT_ENA_M | UART_RXFIFO_TOUT_INT_ENA_M | UART_FRM_ERR_INT_ENA_M | UART_RXFIFO_OVF_INT_...

The problem is that I want to reduce the current latency time I have (2 ms). Is there any way of gettin...
