Just updated my iPhone 7 to iOs 11.3, after that DJI 4go was updated to 4.2.12, my Mavic Air had the latest Firmware update and was in FCC mode:
So here is what happened:
Since in FCC mode we all know that every flight the screen politely asks you to reset your Wi-Fi setting but we always Kindly refuse this right?
Well, I can confirm that the app after my initially startup does NOT ask you to reset your Wi-Fi settings. Of course I checked if I still was in FCC mode and HURRAY, still in FCC mode with all of the 11 channels!
I was a bit curious so I made a screen recording of the whole proces to see where it went wrong if I needed to. But no fuss at all. Besides, there is an iPad and an Android around with older Firmwares so nothing to worry about.
Hope this will calm you and will help you to make your own choice whether to update.
Cheers
thanks you have been very correct and patient I will follow your advice.
just one last question ...
did you use this video guide at the top this thread to go to FCC with Android first?
