After further experimenting, I suspect that one of my ESP32S is not functioning correctly. I tried the “Light touch” build and one of the devices causes the LEDs to both blink and flicker in a random kind of way similar to the jittery servos. The other one seems to work ok and I can send signals from the “jittery” ESP32S to the other (the cap touch wire works but there is no feedback of the sent colour as the ‘send’ LED is flickering). I believe the signals are received in the reverse direction (the onboard blue LED works in this way), but the LEDs give no clues!
