Hi I am using UART code from nRF5_SDK_16.0.0_98a08e2\examples\peripheral.
I have checked loop back with default UART pins,which are 5,6,7,8.
Now I want to interface some sensor (Hardwired ) with this PCA10040 DK. Hence I read on Nordic community that I have to use different GPIOs.
I have changed 5,6,7,8 to 28,29,30,31 and 19,20,22,23 but in both cases loop back did not work.(I did not get data on serial port).
What am I doing wrong ? Please help
