So I have a P4 and
P4P. The DJI goggles work with
P4P with more recent firmware. But my P4 with older firmware, noted in my signature, doesn't work. It keeps disconnecting the telemetry data but shows the camera feed. This tell me the drone needs to have a recent version of firmware to work with the goggles via USB. I'm not updating my P4 firmware anytime soon, so that craft is out.
Today I flew my
P4P for the first time with the DJI Goggle via USB, since the provided HDMI cable isn't compatible with the DJI HDMI RC connector, go figure. Anyway I was thoroughly disappointed in the image quality using USB, less than 720 resolution, fuzzy with artifacts. Downright crappy. The goggle setting was on HD 1080 at 30FPS, so I'm unclear what I'm doing wrong. Maybe my camera needs to match that since I typically shoot video with1080 @ 60FPS. I'll have to buy an adapter and try out the HDMI feed, after I swap my HDMI module from my P3P RC.
Couple of things, ALWAYS take your tablet or phone device with you when using the goggles with P4 craft. I have learned you cannot do two things with the goggles:
1. Set the RTH height
2. Calibrate the compass
The goggles worked good with my Mavic yesterday, wirelessly. You can
see my review here if interested.
It's interesting that these DJI goggles are not very portable, as large or larger than a P4 craft. It appears tough to find a case that fits them reasonable well without being too big, due to the odd shape and size. Yet, they target these goggles to be used primarily with a Mavic, and the primary advantage of that craft is being portable. Hmmm. They don't work well with the
P4P IMO, which is the less portable craft, the craft that should have been target to have optimal performance, give the higher end price point. I hope they work better with
P4P using the HDMI interface, but then you lose all of the advantages of the goggle, abet being mediocre advantages. Maybe P5 will have Ocu-Sync this fall.
