WS2812B + Arduino Nano + RPi3 Not Working

Hello. I have WS2812B Strip, Arduino Nano and RPi3 And trying to setup a ambilight. The arduino+strip works perfectly fine (Default NeoPixel library and the FastLED), but Hyperion on RPi3 doesnt. It sends the set color command successfully but nothing happens.

Followed this instructions: https://hyperion-project.org/t…-ws2801-ws2812b-apa102.8/

My Config:

"name" : "MyPi",
"type" : "adalight",
"output" : "/dev/ttyUSB0",
"rate" : 460800,
"colorOrder" : "grb"

Thanks. BTW if there is any way to do this without arduino please send guide.

Yup, I checked all the baud rates, all ok. When i do ls /dev and arduino is plugged I can see ttyUSB0, when I unplug, i cant see it. BTW There is also a /dev/AMA0, but it doesnt work either, and is still available even when arduino is unplugged

Adruino sketch from the post I mentioned as instructions, Pin 6.

The arduino works, because every time it boots the strip flashes rgb.

Fixed by changing baud rate on both arduino and RPi to 500000. Thanks
