Very nice development!
Installation flawless as described.
Note that QGC now is 64 bit in windows, if You have made own fixes like dual joysticks simulation, switch to 64 bit for these plugin fixes.
Ping Viewer 2.1.0
-I can not make the viewer to autoconnect next time after I make an manual connection.
Instead it always starts with auto device searching waiting for user, and parameters like scanning 120
deg is gone to 360. Sometimes Ping 360 hangs and needs hard restart.
-Sometimes Ping 360 is indicated together with Ping depthfinder, se screenshot
-Cosmetic residue stays in lower right corner from earlier 360 deg sweep.
