I managed to get this working – besides adding the user to group dialout, you also need to be in the tty group. It would be great to see what others have used for their settings as I can see a lot of options e.g., encoders and step, that are not in the corresponding ASCOM driver. Any tips with how folks use the NiteCrawler in indi would be appreciated.
This is done automatically if you use the INDI PPA packages. I use this driver almost on daily basis in my observatory, there are no recommended settings per se, it just works.
