Video Games In Real Life: Duck Hunt + Drones

For your present hardware config, it seems you’re on the right track for time syncing. If you’re messing with SCHED_LOOP_RATE, be sure to reboot between value changes. Seems a bit odd that the default loop rate isn’t fast enough on Copter firmware, and an RTT of nearly 1/2 a second may be indicative of another problem.

I’m going to dig into the RTT loop rate. Any idea what I should be expecting for a RTT rate? (whats “good”)

RTT should be under 10ms.

But if you are trying to use it time_sync over wifi/radio telemetery, them that is expected to failed as the wireless won’t be great to keep timing …
Best move would be to put a GNSS on the RPI and get it update its time with GPSd and Chrony/ntpd. That way you would have the same time reference on RPI and all drones.

Great suggestion! Do you think I would be able to get away with something like this?
