Alright, I think I have tried every possible permutation of switching and configuring DD and still the M200 won’t fly a mission.
I deleted and reloaded DD on to the iPad. Checked and saved the DD flight plan whilst in wifi range and then headed out to my remote site (no wifi). Then I tried the following:
Start up without DJI Go, straight to DD, UAV connects, fly mission button pressed and pre-flight check fails at Controller check due to multiple flight modes (MFM) not enabled as previously noted.
Start DJI Go, check MFM enabled (it was), check able to fly M200 in P, S and A; all good. Land, kill DJI Go.
Shut down UAV and controller. Disconnect USB from controller. Start up. Allow controller and UAV to connect and GPS on line. Connect USB.
Start DD - hit fly mission button, fail at Controller check due MFM again. Get airborne using P mode, try DD fly mission but fail MFM; switch to S mode and try fly mission - fail MFM; switch to ATTI mode and then try fly mission button - PASS controller check but fail at upload of waypoints. Hit Retry upload waypoints button - fail MFM. Hit Re-plan waypoints button - fail MFM.
Tried all again with DJI Go enabled in the background - no change. Tried with obstacle avoidance on/off. Tried different USB cables.Tried with MFM disabled.
Finally, tried altering flight plan route but then DD won’t give me a fly mission button - I just get the Save button and nothing I do after that gets me a fly mission button back, although DD says “flight plan saved, connect drone to fly” at bottom of screen.
Pack up. Drive home.
Can anyone see a fatal flaw anywhere (apart from hovering in ATTI mode and attempting to make screen selections at the same time)?
Has anyone used DD with an M200?
