I was being a little sarcastic because of the lack of communication regarding firmware update for the hub device. I do firmware updates for everything that I can but when I look at the firmware update outlet on the hub device – I Assume that so long as everything I have is updated then whatever Updates are in all the batteries will simply transfer over to the Hub Device and be updated. If the hub is meant to be updated then DJI should be very clear about this. It would be useful if they could read and write English.
