LED Codes

The IBIS tracker has a single LED that uses different on/off patterns to communicate state. Use this page as a reference when something looks off.

Button-driven states

These are the patterns for VYRO VR’s current shipping firmware:

Pattern	Meaning
LED comes on after a single press	Powered on and broadcasting
Short purple flash on a single press while on	Reset sent
Flashing blue once per second	Pairing mode (3 presses) — see Pairing. A single press, or a power-cycle, exits it
Cycling through rainbow colours	Side calibration (2 presses) in progress. Keep the tracker still on a flat surface until the cycling stops. Older firmware shows one flash → solid → 4 rapid flashes instead
Solid then fades out, or just fades out, when you hold the button	Powering off (which one you see depends on firmware version)
Slow fade / pulse, and a USB drive appears when plugged into a PC	DFU mode (4–5 presses) — see DFU Mode

After power-on, the LED goes quiet once the tracker is connected to the receiver and streaming normally. If a tracker is on but never shows up in the SlimeVR Server, work through Tracker Won’t Pair.

Charging states

When the tracker is sitting in the charging dock or on a USB-C cable:

Pattern	Meaning
Charging LED on	Currently charging
Charging LED off (with USB plugged in)	Fully charged, or no charge current — reseat the tracker if it was empty

Battery warnings

Pattern	Meaning
Tracker drops off and won’t power back on	Battery empty; recharge before retrying

Unconfirmed

Earlier versions of this page listed a “periodic double-blink” low-battery pattern. We haven’t confirmed that against current firmware, so treat the SlimeVR Server’s battery readout as the reliable indicator. If your tracker’s LED is doing something you can’t find here, post a short clip in the VYRO VR Discord — easiest way to identify it and improve this page.
