Finally got around to updating today. All good. Updating from AC firmware 1.6 to 1.8 took just about ten minutes on the dot. Updating from RC 1.5 to 1.6 took around two minutes to complete. All good connecting to dji go, all good connecting to Litchi. Did a compass calibration and a very low 60 second lift off (battery at 30%) just to make sure everything is ok, which it is. It may be just because the weather has grounded me for a couple weeks, but the motors at idle sound different- kinda ramped up a bit. Liftoff was fine. Might just be all in my head. I noticed no new NFZ's other than the ones I'm used to seeing.
For anyone interested, this is how I proceed each update, having never had an issue yet. I use an Ipad
air2 at IOS 9.1 for flight.
- Power up the full system and take notes of all custom settings. You need to do this because while many settings remained the same, some defaulted. Check camera and video settings too.
- Power system down
- Delete or transfer video files off of the card you have been using successfully to film. That goes for any folders, media or otherwise. Everything off. Then drop the Bin file on the card. Using your filming card ensures that the card is working and formatted properly. I do not like using new, unproven cards for firmware updates.
- Put the card in the bird, remove any gimbal guard, place the bird on a level surface and with a battery charged at least to 50%, turn on the bird. Let it finish updating- approx ten minutes.
- Power off the bird, remove the card and check the card for success on a computer. Once done, delete (or transfer to archive) all files so the card is empty once again. Place the card back in the bird but
do not turn on the bird at this time.
- If necessary and
without turning on the RC, turn on tablet/phone and update DJI Go. I had to do this. I was one rev behind. I always update DJI Go if need be before an AC/RC firmware update. Once the app is updated, force close out of it and for good measure, close out of any other flight apps such as autopilot or Litchi, etc, which might be open in memory.
- Connect the cable from RC to tablet and turn on the tablet and open DJI Go. It should now show an RC update is needed. Proceed and once done, power down but
do not restart yet. Force close the Go app as well.
- Turn on the RC and bird and wait 30 seconds before opening the Go app. This allows the bird and RC to make initial connection.
- Open the Go app and confirm live feed. With your previous notes, reset any custom settings. Be sure to check all camera settings too.
- While still connected to wifi, open any third party apps such as Litchi to establish connection is ok.
- Reformat the SD card within the DJI Go app.
- Done! Do a compass calibration in the field. That's the only calibration I personally do. I don't do an IMU or gimbal unless it says it needs it or there is odd flying behavior. I do a modest, low level close range flight for a battery after a firmware update to confirm all is well.
And now...for that flight! I'll report back if anything is screwy.
