Just wanted to share my IMU calibration experience with everyone.
After my maiden, the drone seemed a bit erratic and not as predictable, so I went ahead and opted in to do the IMU calibration as I have with all my previous generation products. I ensured that I was on a level surface, away from any magnetic interference etc. I opened the sensor menu to get into the IMU Calibration and began the process. In step 1, the app asked me to set the drone down normally (legs down, normal position). Step 2 is to lay the drone on its left side, and step 3 was to go back to the "normal" position, but with the drone facing 5 oclock. At this point, I let the drone sit in the desired position for 10 minutes and but the process would not let me continue. I powered everything down and reached out to DJI support immediately. Attached are the screenshots of the IMU instructions.
Unfortunately, the DJI rep offered little assistance but opened up a ticket with the developer to look into this issue and get back to me.
I tried this process a few times, and each time it would not let me move past step 3 - I assure you I was doing everything down to the T.
At this point, I was a bit worried that if I try to take off with a half-calibrated drone that it was bound to wreck into something, so I reached out to youtube for a bit of assistance. Thankfully, DJI Support released a video on the IMU Calibration process, however, step 3 in the instruction video was quite a bit different than what the app was telling me to do. Since I had nothing to lose, I gave it one more shot, but this time followed the steps outlined in the video and I was able to get through the calibration process. For those curious, step 3 is to lay the drone on its right side (opposite step 2), step 4 is to place it on its back legs with the camera pointing up, and step 5 is to rest it upside down.
My conclusion is that the app is displaying the wrong image for step 3 & 4 and I am hoping DJI will release an update to the android version within a few days that addresses this. In the mean time - I would advise holding off on calibrating the IMU. If you happen to get stuck, follow the video instructions like I did and you should be in the clear. Ill put this turkey up in the air this evening and let you guys know if it flies away or decides to frontflip into the ground. Cross your fingers.
