Orientation issue

We were able to get the doodles communicating in most environments, but there is an orientation of the IF800 that trigger an increase in activity % and a decrease in MCS to 0

This causes the video feeds to tear and become unusable.

Theory

The antennas are in such an orientation that they see each other as activity, and therefore do not transmit data as they are waiting to talk. Data doesn't get through, the radios start dropping packets, start retrying some packets, and then the MCS drops down to 0 and this snowballs the issue

What we have tried

  1. Turn off 1 antenna: we were not able to recreate the issue

  2. Fix MCS at 4: it was harder to recreate the issue at MCS of 4, but the issue persisted for longer when it DID happen. Even when re-orientating the drone

What else we can try

  1. We did increase the bandwidth to 26mhz and this seemed to fix the issue. HOWEVER, this was one test that lasted 10 minutes

  2. Get rid of "optimize for robustness" such that ALL MCS can be used. This will allow minstrel more options to flip to in that specific RF environment

  3. Put SENSE on the radios. Possibly switch channels...

  4. Monitor the acivity, packet loss, and MCS such that when those look bad we drastically lower video bandwidth so this doesnt snowball into a larger issue
