LED Indication¶

SmartBeam uses separate LEDs for the beam itself, battery charging, and the timing system state.

Where to look¶

SmartBeam with labels identifying the beam state, system state, and charging state LEDs

Beam state: an arrow-shaped LED pointing down the top of the unit, within the top light-bar.
System state: LEDs at the two ends of the top light-bar.
Charging state: an LED shining through a small hole on the side, directly above the USB port.

The arrow-shaped LED always indicates the state of that unit's beam.

LED colour	Beam state
Red	Beam broken.
Green	Beam established.

This is separate from the system-state LEDs: the arrow shows the beam state, while the ends of the light-bar show connection and timing states.

The LED above the USB port shows orange while charging and green when full. See Charging for the full indication table and USB power instructions.

The LEDs at the ends of the top light-bar indicate the following states.

Flashing white	Searching for a Bluetooth connection.
Solid white	Connected, but not included in the beam setup.
Solid yellow	Hot beam: the next expected beam break.
Solid blue	Idle and disarmed.
Solid purple	Idle and armed.
Solid teal	The system will arm when the beam is tripped.

LED indication	Meaning
Red	Beam broken during timing.
Green	Beam complete during timing.
Rapid orange flashes	Arming countdown.
Blue flashes for about five seconds	Paused countdown.
Brief rapid red flashes	Timing cancelled or timed out.
Dim purple alternating between the two system-state LEDs	Firmware transfer in progress, on firmware with update-light support. See Firmware Updates.

Brief, rapid random-colour pattern	Identifying the device.
