nRF52840 mini flow control?

I’m using the nRF52840 mini development board with Arduino and I would like to use the built in flow control. I can see that in the header file it is disabled. Is it possible with Arduino to enable hardware flow control? How would I go about this?

Do I

  • Go into the header files and simply change HWFC to enable?

  • Or do I just use some command in the Arduino library?

    You’re probably going to need to program these through the Nordic SDK to be able to use CTS/RTS flow control. I’m not aware of that being implemented under Arduino. You could try modifying the header file to see if that works, but I don’t know if the underlying code for hardware flow control is actually working.
