I have had P3 Adv for several months and it is has been fine. About 6 weeks ago I upgraded to the V1.8.8 and then this problem started. It is still there with the latest firmware upgrade 1.9.6 I fly and at short range (few hundred meters) the craft will go from full signal strength (control & video) to disconnected and then continually cycle in this disconnected state. By cycle I mean 1 red bar for control; and then video goes from 5 bars to none and back again. Repetitive disconnect messages. It will stay in this state for minutes. Rarely might recover. Then eventually do a RTH. While in this state I have checked remote antennas (good position); turned each way; moved left and right - nothing helps. After the RTH, at the time the props stop it will connect with 5 bars on each. once it reconnected a few meters off the ground. This behaviour is fairly typical - but doesn't always happen. I might then fly a km away without problems. My analysis: -The areas I am flying in on beaches and it has happened in several locations so I don't think this is RF interference. It would reconnect faster at closer range if it was and it doesn't... - direct LOS. no trees. Over water off beach in every case so shouldn't be these issues. - why it reconnects when motors shut down may be a hint? - no physical damage or reason to suspect damage to antennas (I did have a cracked base on one remote antenna but I fixed it and all looked fine). - the nature of this looks like a software bug in not reconnecting and just cycling..... my suspicion... but have no idea why it would just crop up. Does anyone know if this is indicative of a control link problem which causes the video to drop in and out? deathly drones log below. In this case it did recover a couple of times in flight but then eventually did an RTH.
