Wismo 228 flow control


#1

Hi

I am trying to set the flow control of the wismo 228.
I have tried this command
AT+IFC=2,2
and the wismo sends an OK reply but the flow control doesn’t seem to work correctly.
Any idea how to set the flow control

Your help would be greatly appreciated

In what way(s), exactly :question:


#3

If the RTS pin is high (indication that the UART of my microprocessor is not ready to receive new data) the wismo still sends data.


#4

How do connect the RTS between the module and microprocessor? keep it right.
