Dropping throughput appx every 30 seconds

[Ingineerix]

First off, thanks for this!
Drone Firmware Version 2.3.3
AP is Ubiquiti UAP Pro
AP shows connection is maintained, but IP level fails about every 30 seconds and the outage lasts 30 seconds. Regardless of IP used fixed/dhcp.

I see something similar. here's ping output showing connectivity going away for about 30 seconds every 30-60 seconds:
