Hi, whenever I disconnect and reconnect the power from my board the dmx over wifi function doesn’t work. The other part of the code, which is like a strand test to check the strip, still works. I have to reload after every power cycle. Before turning the power off, every function works and I can drive the LEDs wirelessly from various software programs on my computer
my set up:
Huzzah esp8266 feather, lipo 3.7 battery, data on pin 12, strip ground to the board ground
90 LED neopixel strip on 4 1.2v 1.9amp li Ion batteries wired serial
This example will receive multiple universes via Artnet and control a strip of ws2811 leds via
Adafruit's NeoPixel library: https://github.com/adafruit/Adafruit_NeoPixel
