Also it's not a problem, but FWIW the "alpha" value doesn't seem to have any effect on the status LED — though I'm not sure what alpha should mean in this context anyway since the color value's not composited over anything.
This turns the light to full white:
echo 1,255,255,255 > /dev/status_led
Light remains full white:
echo 0,255,255,255 > /dev/status_led
Alpha value doesn't appear in the stream from the device:
head -c 40 /dev/status_led
255 255 255255 255 255255 255 255255 255
I'm testing with an OAK4-D R7 / OS RVC4 1.11.0 (debug) / Agent 0.9.0.
