Drive the on-board RGB LED from scripts

The on-board RGB LED is the device's primary feedback channel for in-the-field operation (no display needed). Control it from scripts with the led primitives.

Primitives

led color "#ff00ff"             # solid magenta
led pulse "#00ff88" 1000        # pulse green, 1 s period
led blink "#ffaa00" 200 200     # blink amber, 200 ms on / 200 ms off
led off                         # all LEDs off
led brightness 50               # 0-100

Default firmware patterns

Color	Pattern	Meaning
Green	Solid	Powered on, idle
Magenta	Solid	Script running
Cyan	Solid	Autostart script running
Orange	3 blinks	Script execution canceled
Red	3 blinks after script	Wrong USB port or charge-only cable on USB
Red	Solid	File-system error

Recon mode interaction

recon mode on overrides all LED commands — the LED stays dark regardless of script state. recon mode off restores the prior color and pattern. See Recon Mode.

Use cases

Ack-after-payload — flash green when a script finishes successfully.
Visual handshake during plant-and-trigger — blink cyan to confirm autostart fired.
Status badge for TraceNetwork agents — assign each device a distinct color via identify.
