First LED in the led strip doesn't get recognize at all

[JINODK]

I'm using a NodeMCU running colorchord and had NUM_LIN_LEDS changed to 30 before compile and burn it, so far everything seems to work just fine, except that the first led in the strip does not get recognize by the ESP and output nothing, the rest of the strip is working as it should be.

• I'm using the esp8266 as it is the best choice that i have for now
• The strip I'm using is WS2815 as it last longer than the 2812 one, as far as I'm aware, the WS2815 is just a 2812 with dead string problem being fixed and it runs on 12v
• I have tested it with Adafruit's neopixel rainbow example in the arduino ide and the first with the rest of the strip light up just fine
• I also tested with the esp8266ws2812i2s example by sending UPD packets to ensure that it's not the driver problem, same all light up result

I also had that issue. I ended up putting an LED out of site on the back of my project board so the first one was not being used rather than trying to fix it.

I am actually having a similar issue right now, but I don't actually know why. I've tried advancing my LEDs by one, in the actual sending code and it still isn't right. This is even weirder because it's on the STM32F303!!

If anyone figures it out, let me know!
