Hi ilHw_4713311​,

Would you please let us know the UART pins you have selected? Also, what error or problem you are while testing?

FYR: Re: CYW20706 Can I use i2c and PUART(rx,tx,rts,cts) at them same time?

Also, check the comments in wiced_hal_puart.h-

Remember that P# is the physical pin number on the board minus 1.

         Ex: Board Pin 33 = P32.

Hello.

I'm using CYW920719B2Q40EVB-01 board, and want to use PUART flow control with PC comport via USB.

I just need sample code to use PUART flow control with CYW920719B2Q40EVB.

In my test

wiced_hal_puart_select_uart_pads( WICED_PUART_RXD, WICED_PUART_TXD, 0, 0);

-> I could send tx and PC received rx;

wiced_hal_puart_select_uart_pads( WICED_PUART_RXD, WICED_PUART_TXD, WICED_UART_2_CTS, WICED_UART_2_RTS);

-> No data were transferred.
