Thank you, with this hint and the post https://forum.m-labs.hk/d/191-drtio-master-satellite-ping-failure, I was able to write the corresponding JSON files for the device_db and generate them for the master/satellite system. Things seem to be working somewhat ok, but I want to check that everything is in order first. Then I plan to write a short manual here, because the relevant information is scattered between forum posts, github code and required a lot of trial and error. Unless I overlooked a manual somewhere on how to write the JSON file for the tool you mentioned?
