Hi @mlebret,
Thanks for the report. Re the Navio2, could you test with 4.6.0-beta? It’s probably clear but this is the 4.6 release notice so reports here really should be for 4.6. If you’d prefer to keep using 4.5 then could you re-post in the 4.5 category?
Re the LDRobot lidar, yes, that definitely sounds like a power issue so we probably can’t resolve that in the AP software. The LDROBOT LD19 Lidar360 is not even on our list of supported lidar as far as I can tell.
