UART2 problem

[baggior]

only the first message is correctly sent via UART2
the others are garbled

bug of esp idf uart drivers and then in the arduino framework
espressif/arduino-esp32#991

workaround on idf not in arduino framework
espressif/esp-idf@4052803

Hi. I am using all 3 UARTs. One for debug and 1 for comms with a motor controller and the other one I want to use to communicate with a VSD. 2 work 100% but on UART1 I will see data not show correctly at random. It will not send all the data all the time on that UART. So UART0 and UART2 works 100% but UART1 that is mapped to pin 4 and 15 will drop data.
