Modbus on UART0

Hello ESP experts. I have tested the modbus slave example with Uart2 and everything works fine. However I need to use Uart0 instead. I have changed the console port to uart1 and changed modbus port to uart0. Even though the console is now successfully moved to uart1, but modbus doesn't work on uart0. Any suggestions as to what could be causing this?

Hello,
Would you please send full details regarding your errors? Which IDF you are using? What type if error you are facing? Is it working on UART1 interface?
