I just found another possible flaw with the app that might explain my second problem. When not connected to the RC, the Go App is way off in showing my current position on the map. I can't blame it on the mobile device GPS since Google Maps shows my correct position. This occurred on the Samsung tablet and HTC 10. On the HTC I just confirmed I have it set for high accuracy which has it use GPS, cell signal, USB, WiFi and Bluetooth to determine location. It also shows GO app using this feature.
Aloha Dan,
The flaw is not with the app. Your Android device, like mine, is not an approved device. That is why there are problems. But, we solve our problems!
Well, you answered my first question with this second post. What version of DJI GO are you using? DJI just came out with 3.1.2 but the versions of DJI GO after 3.1.0 do not have Google Maps. We fly a network of at least three computers. Each computer in the network has to connect with the other two under wired and wireless conditions.
Like you noted, sometimes it is best to turn on the remote controller before the device or soon after you turn on the device. This allows the device to recognize and shake hands with the remote controller. (BTW, this is a very successful way to solve computer connection problems but cannot always be done.) Try your start-up procedure, while leaving debugging on, and see if it works.
We need to know what version of the DJI GO app are you using? There have been problems with the map not updating the position of the Phantom. That may be your "thousands" problem or related to it but we need to know what version you are flying. Maybe a newer app could solve that problem.
The last telemetry read-out is the Vision Positioning System (VPS) altimeter for landing when you get below 3 meters (10 feet). For example, I live and fly in the jungle and like to go up to the "flats" where there are landing spots and even two landing pads we set up over grass. I am not able to see the Phantom when it gets within 30 feet of the ground but the live view shows everything except my altitude. When I get withing 10 feet of the ground, the VPS altitude reads out the local condition. After a PAN scan for obstructions, I am able to confidently land using the VPS read-out.
The Radar is there to save your Okole when you get lost or disoriented. The direction of the Phantom and the camera and the attitude of the Phantom are all represented in the Radar. You might want to pay more attention to it and learn how to take advantage of its information. It is kind of cool once you get into it.
The RC has no GPS at all and depends on the device for GPS orientation. The Google Maps uses the GPS of the device to give the correct location. If the RC is not connected to the device, DJI GO cannot locate you or the Phantom.
Hope this helps!
Aloha and Drone On! |
