@me-no-dev Well, for some reason I couldn't get the STA version of my UDP Tx test working... but I did end up trying unicast instead of broadcast as SoftAP, and there were no significant packet loss problems all the way down to 1 ms. I got a 97% reception rate at 1400kBps bandwith with 1400-byte packets and 1 ms between transmissions.
So the problem is definitely in the fact that it's broadcast instead of unicast. There's some invisible wall of impossibility in trying to UDP broadcast packets more frequently than 25 ms.
FYI, I'm testing this on the update_sdk_2.1.0 branch, since UDP broadcast is broken-ish without it
