UART RX not working on nRF52832 DK board

Hi.

This might be because P0.10 is used for NFC.

On the nRF52-DK, P0.10 is used for NFC. If you want to configure the NFC pins as GPIO's you can find more information here:
https://infocenter.nordicsemi.com/topic/ug_nrf52832_dk/UG/dk/hw_nfc_if.html

By default I think that P0.06 is used for TX and P0.08 is used for RX.

Br,
Joakim

Hi.

[quote user="paul0208"]I cannot use P0.08 and P0.10 for uart?[/quote]

Which device are you testing this on? Is it a Nordic DK?

Also if you add information about SDK version etc. it's easier to support you in future tickets.

I was use P0.08 for tx and P0.10 for rx.
I have change to P0.6 for rx and P0.7 for tx, then APP_UART_DATA_READY event is working.

I cannot use P0.08 and P0.10 for uart?
