Hi,
I know that the nRF52 Dongle should be able to use printk() to debug. I have used it with the Serial Terminal before and it was working.
However, when I program the dongle with a project I found online. Everything was working except that the device/ port is not showing up in the drop down list from the Serial Terminal in nRF Connect for Desktop anymore. I have attached the kconfig and the imports below:
