Hi, I have been experimenting with the Direct Test Mode program. I am using an nRF9160 DK, specifically the bluetooth chip nRF52840.
The Direct Test Mode is not officially supported by this dev kit, but I was able to compile it by creating a .conf file with just the following line:
CONFIG_NRFX_TIMER3=y
The program works as expected with nRF Connect's Direct Test Mode app, except that I was not able to get UART communication working. printk-commands are not getitng through, which is my main use case for the UART connection as I want to do some debugging with the printing.
Any specific tips on how to get the UART and printk working? I am lost on what I should try next.
