RE: Modify DTM FW UART Tx & Rx pins

Hi Fabio,

Really sorry for the delayed response. We are currently at low staffing due to the holiday season. So please expect some delays in the responses.

You can create an overlay file and save it in the direct_test_mode folder in the name nrf52840dk_nrf52840.overlay. You can check this blog on how to create overlay files. When you build the sample, a new build folder will be created and within the zephyr folder in here, you can see a zephyr.dts file which gives details regarding all the pins and configurations for this board. Here you can see the TX and RX pin initiation and once you create an overlay file, it will literally "overlay" this dts file and your configurations will be considered.

Kind Regards,

Priyanka
