yep I agree although the new version you indicate below is on good way to solve that issue ! It’s not yet working but at least once identified on rakwireless website it comes back by itself in Wistoolbox app (but the app still keeps unidentified) 
Thanks for link
May I suggest that version be indicated in files names on your files server to make it a lot easier to find out if a new version is avalaible or not ? 
Should not make much differences as Ubuntu is based on Debian 
No idea what it is but for AppImage there are no such settings. All you need is to add linux user in dialout group !
For that version it’s a lot better than previous one !
→ I connect the RAK3172 at my computer, starts the app and then it discovers the device. It just displays a warning that I have to manually select the type of device as it could not find it by itself. No problem I select my board and then it communicates with it !
It just complains that it can’t get all details of board and that I have to switch in AT mode but it’s unable to do it ! if I do the switch by myself and then reconnect Wistoolbox it displays all infos properly:
→ I’m now able too to create and edit a template without any problem.
→ Firmware part is still not working (the AppImage is missing some Pithon libraries needed for app to flash fw !
Let me know if you need additional tests or infos and impatient to test the next version of Wistoolbox when it’ll be avalaible
In the meantime I’ll try to find a way to upgrade the device RUI version…
