Updating Firmware

IBIS firmware updates ship occasionally with bug fixes and new features. Updates are optional — your hardware works fine on whatever firmware it shipped with. Update when you want a specific new feature or when the VYRO VR Discord flags an important fix.

When to update

  • A new SlimeVR Server feature requires updated firmware (rare; the server announces this)
  • VYRO VR posts a known-good firmware release with fixes
  • You’re troubleshooting an issue that’s known to be fixed in newer firmware

If everything is working, don’t update for the sake of it. Stable firmware in production is good firmware.

Updating trackers

Tracker firmware is updated through the SlimeVR Server:

  1. Plug the receiver in, power on the tracker.
  2. In the SlimeVR Server window, open the tracker’s detail panel.
  3. If a firmware update is available, you’ll see an Update firmware button.
  4. Click it and wait until the server reports the flash is complete. Do not unplug or power-cycle the tracker mid-flash.
  5. Power-cycle the tracker (hold to off, single-press to on). It should reconnect to the receiver immediately — pairing is preserved across firmware updates.

If the tracker doesn’t reconnect after a power-cycle, re-pair it: Pairing.

Updating the receiver

Receiver firmware is updated with nRF Connect for Desktop — Nordic Semiconductor’s free toolset.

You need two apps from inside nRF Connect for Desktop:

  • Programmer — flashes new firmware onto the receiver
  • Serial Terminal — talks to the receiver over USB to confirm version, status, and post-flash behavior

Steps

  1. Install nRF Connect for Desktop for your OS, launch it, and install the Programmer and Serial Terminal apps from the app library.
  2. Download the latest receiver firmware image from the release notes VYRO VR points you at (usually a .hex or .zip file).
  3. Plug the receiver into your PC over USB.
  4. Open Programmer, select the receiver from the device dropdown, drag in the firmware file, and click Write. Wait for the flash to finish.
  5. Open Serial Terminal, connect to the receiver’s serial port, and confirm the firmware version reported matches what you flashed.
  6. Re-launch the SlimeVR Server and confirm trackers reconnect.

If an update fails mid-flash

A tracker that interrupts mid-flash boots into DFU mode automatically (slow LED flutter) — see DFU Mode for recovery.

A receiver that fails mid-flash usually stays visible to nRF Connect for Desktop’s Programmer — re-flash with the previous known-good image from the same workflow above.
