P3P Transmission Loss Causes?

[Pegasus Robin]

Hi all, I hope you're well. Had some strange things happen when I've been doing some real estate work and my P3P suddenly loses video signal and says transmission lost. What could be the cause of this? I'm flying at a fairly low altitude and the quad is always very close at line of sight. This has only started happening since I got my iPad.
My flights are usually close to houses but there is enough clear space and even wide open sea when I fly. Could it be wifi interference or a dodge cable? I'm stumped

I have an iPad. It has problems if my phone's Bluetooth is on. When the Bluetooth is off it runs great. Don't know if it correlates, but I'm flying a p3 s.

Usually dodgy cable.

I'll change the cable over and turn Bluetooth off and see if that works. Thanks
