Using P07 (CTS) as general output pin

Hi Johanan,

The way you did it is one way to do this.. You could go through this documentation here: https://infocenter.nordicsemi.com/topic/ug_nrf52832_dk/UG/dk/dyn_hw_flow_control.html?cp=5_2_4_3_1_0

You could also just disable UART0 in the overlay if you are not using it.

No, but I set the pins to null, as so:

/* Disable hardware flow control by removing RTS and CTS pin definitions */
&uart0 {
	UART_RTS = <>;
	UART_CTS = <>;
};

Hi Johanan,

Making changes to an overlay files overwrite the dts file without directly making the changes, so it would be no problem doing it that way. Did you however change the CTS pin in the overlay to a different one.?

I am using dk52 52832 boare, it does not look like a good idea to change that dts file. Why adding an overly file is not working?

If you use nRFConnect SDK, you must modify dts file
