I tried to follow the steps described in this document http://docs.rakwireless.com/en/Cellular/RAK8212/Software-Development/Get_start_with_RAK8212_and_Hologram.io_using_RUI_firmware_V1.0.pdf
and I wired my J-link Edu Mini programmer to the board accordingly and used an external battery as a power source. But nrfgo Studio is not detecting the target as you can see in the attached screenshot.
I’m using the latest versions of all nrf and jlink softwares.
Could you please tell what else can I do?
