I've had my phantom 3 professional for about 2 weeks.  Have flown it a few times and really like it.  I've flown a few other quadcopters in the past so I'm not completely new to this.  I have still been extremely careful so far.  Some may even say overly cautious.  No crashes.

I went to fly the other day and went through my preflight checklist.   Armed the motors and they sound fine, GPS lock is good and remote is linked to the quadcopter (green liight on remote).  Fire up the pilot app on my iPhone 6 and it won't connect.  Just get the disconnected message at the top of the screen.  Also, I don't get the 'trust this computer' message that I was getting.

Any ideas what to try?

Some have mentioned starting things in a different order. Personally, i start the remote, then the app and then the phantom.  For me, app, remote and phantom also works.  The phantom, for me, is always last.

Thank you.  I think I've tried every possible order.  I'll give this a try again though.

I'm leaning towards an issue with the USB port.  I've tried different cables and a table with no luck.

i have the same problem. p3p with disconnected message on iphone 6

I always start remote, app, then bird. Opposite order for turning off.  I have had some connection issues, but have simply unplugged my ipad from the remote, then plugged it back in and it connects.

Did you fly with this device before? Do you have jailbreak in your phone

Let me know if you figure out anything.  At this point I'm thinking about returning it.

I flew it s few times without any issues.   The iphone is not jailbroken.   Not sure what changed.

I've tried unplugging the iphone and plugging it back in without any luck.  Frustrating.

Return it is the better choice, but i’m in Brazil, so difficult to do this. I will try to upgrade using the hdmi module board and see what happens.

Hope you are able to get it worked out.  

Shipped mine back today.  Was disappointing.  I really liked it and enjoyed the few times I was able to fly it.  Just to expensive to have and not be working properly.
