Can you change the RGB to BRG in the settings? I have a ESP8266 with a WS2812 led strip but when I press blue I get green and vice versa. I had wled before and there I could change the color order from RGB to BRG.
I had the same problem. You have to upload the sketch with arduino IDE and change the following lines:
NeoPixelBus<NeoRgbFeature, Neo800KbpsMethod>* strip = NULL;
to
NeoPixelBus<NeoRbgFeature, Neo800KbpsMethod>* strip = NULL;
and
strip = new NeoPixelBus<NeoRgbFeature, Neo800KbpsMethod>(newCount); // and recreate with new count
to
strip = new NeoPixelBus<NeoRbgFeature, Neo800KbpsMethod>(newCount); // and recreate with new count

This is hardcoded in the Sketch. Maybe we add a binary for future flashing of the flash tool.
Hi.
I am changing the color definitions:
NeoPixelBus<NeoBgrFeature, Neo800KbpsMethod>* strip = NULL;
and:
strip = new NeoPixelBus<NeoBgrFeature, Neo800KbpsMethod>(newCount); // and recreate with new count

Please help me.
Looks like you don’t have the neopixel library installed. Add them in arduino library manager.
