Hi, kzsolt2
→ From what I find, CTS is input, RTS is output like below.
(This picture is from ST chip’s datasheet)
Because WizFi250 and host MCU have CTS/RTS pin, it can be controlled bi-directional.
Also, If you are using a UART with baudrate below 115200, you do not need to use the RTS / CTS pin.

Tom

Dear Tom!
The wizfi deafult is: hardware flow control disabled
Ok, then I limit to 115200 (I no need more) and do not use hw flow control.
If my reverse engineering is correct, then:
wizfi nCTS out pin need to connect to MCU’s nCTS in pin.
wizfi nRTS in pin need to connect to MCU’s nRTS out pin.
To clearify this wizfi250pg at appendix refer to HW flow control, but does not draw a correct pin connection between MCU and Wizfi.
