Hi folks, Bit of a long post because I wanted to detail the strange things happening to my P3P, lately, and I wonder what you make of it all: A couple of days ago, I have updated the firmware of the RC from v1.4.30 to v1.5.70, and the Phantom 3 Pro and batteries to v1.6.0040 (from 2015-12-22). I have since done a couple of successful flights, although I once shortly got a 'signal loss' during flight. I attributed that to using a new smartphone instead of the tablet I normally use. Yesterday, I wanted to do another flight, but at the startup/check-up screen I got the warning that the radio channel quality was poor, probably due to interference, etc.. Also, the pre-flight calibrate button was just not there. Furthermore, at some point a window popped-up with a slave (slave name: 9, I think it was) requesting control over the gimbal! Of course I denied it. I have never seen this before. Also, as far as I know, the Phantom 3 Pro does not have the option to be controlled by multiple Rcs, only the Inspire has that option. (And I absolutely used the firmware update software from the Phantom 3 Pro). I restarted all a couple of times, sometimes getting the message 'no-connection', sometimes getting the message 'no signal' and usually getting the slave-control request again as well. Always with the 'poor radio channel quality'-warning, and no calibration button. And then, starting up all of the hardware once again, all over sudden, all was back to normal. I did a successful flight, although the Phantom was noticeably less stable when hovering in front of me in the air (I have had that a couple of times before, and attribute that to the weather, also because I had around 20 satellites to work with). What do you make of that? I'm thinking there might actually have been some kind of radio interference. I'm not sure from what, because I live out on the countryside, with the nearest neighbors several 100s of meters away, no factories, no communication poles, etc... Solar flares? (Trying to take over my phantom?! ). Or is the latest firmware update unstable and to blame? Please let me know what make of all this. Cheers!
