I am developing wireless wind sensors using esp32. What I have is 2 esp32's. One of them at the sensors transmits the data using esp-now which is not wifi or bluetooth, but an esp specific protocol that has low latency. The other esp32 receives esp-now and can relay either via wifi, or more generally plug directly into pypilot via usb. The intention here is to eliminate the lag issues with tcp and even udp on both esp32, as well as linux, as I even find 500 millisecond hiccups on wifi data to be common and this is an issue when reacting to wind gusts.
