Weak RC signal

[Pim-K]

I have been flying this morning about 30 km from home. Very nice flight no problems.
When I got home did an other flight and got the message: 'weak rc signal' standing right next to the P3A.
After starting everything up a few times the message disappeared.

A flight later I got 'disconnected on the iPhone. Had to boot the phone to get 'save to fly'.

How can I get a low rc signal? No interference in the area.

too close to the phantom. You should be a distance from it.
