Communication Protocol 3000
BTN - Button ID according to the configuration in
RED, GREEN, BLUE- Color intensity for each base color. Values are from 0 (No color) to 255 (Full color). Plain buttons that support only on/off light should ignore values of these parameters (except if all set to zero – same as turning light off).
STATE :
"0" or "Off" (Color parameters can be ignored). "1" or "On"
"2" or "Slow" for slow blink "3" or "Fast" for fast blink
RESULT – OK if command has been executed.
“#DEV_ID@RGB ERR 003” should be returned if any parameter exceeds its limits (for example – Button ID does not exist).
Example:
Master Device:#03@RGB 1,0,255,0,1CR
Result: Device Application needs to light on its button 1 and set color to Full green.
Device Application response: ~03@RGB 1,0,255,0,1 OKCRLF

Device that implements lit buttons should reply this request and give its button color and state. Device can support full color buttons or just plain on/off lights.

Device that implements label (LCD) should react to this command and set its “LCD” (or text label).
LCD_ID – Label (LCD) ID according to the configuration in
TEXT – The text to display in the label (This parameter should be enclosed by quotation marks, character 34 in Ascii)
RESULT
– OK if command has been executed.
“LCD ERR 003” should return if any parameter exceeds its limits (for example – LCD with this ID doesn’t exist).

After answering OK, the master will send to the device commands to refresh user interface elements like RGB buttons and LCD labels. For example:
#DEV_ID@RGB 1,
#DEV_ID@RGB 2, …(All RGB)
RED, GREEN,
