BLU2Lite User Manual
The BLU2Lite is a battery-powered Bluetooth Low Energy (BLE) camera status indicator. It connects wirelessly to your action camera and displays recording status, warnings, and errors through LED indicators, giving you peace of mind that your camera is getting the shot.
BLU2Lite supports GoPro, DJI, Insta360, and Sony cameras from a single device. The camera type is detected automatically during pairing.

Quick Start Video
Device Components
- Multi-Function Button — Powers down the device, initiates pairing, and enables firmware update mode
- Connection Status LED (Blue) — Indicates whether the device is searching for a paired camera, actively connecting, or in pairing mode
- "GoPro" Status LEDs (Three) — Display camera recording state, warnings, and errors once connected
Camera Status Indicators
Once paired and connected, the three camera status LEDs show:
| Red — Camera is recording | |
| Green — Camera is in standby (ready to record) | |
| Yellow flashing (with green or red) — Warning: low battery, low storage, or high/low temperature | |
| Yellow (solid) — Error: dead battery, no SD card, no remaining space, or camera overheated | |
| Blue — Searching for paired camera | |
| Yellow & blue blinking — Pairing mode active |
Note: Warning and error details vary by camera brand. GoPro, DJI, and Insta360 provide battery, storage, and temperature status. Sony shows recording status but cannot start/stop video and does not provide battery or storage warnings.
See the Camera Support for details.
Operating States
| State | How It Works |
|---|---|
| Sleep | Low-power state. A slight shake or tilt wakes the device via the built-in accelerometer. |
| Searching | After waking, the device searches for your paired camera for several seconds. If no camera is found, it returns to sleep. |
| Connected | Camera status LEDs are active. The device remains on until the camera powers off or disconnects. |
| Deep Sleep | Only a button press wakes the device. Use this for travel and transport to prevent unnecessary battery drain. |
Waking Up
The built-in accelerometer detects movement to wake the device. A slight shake or tilt on your helmet is generally enough. Once awake, the device status LED briefly shows battery level, then the device begins searching for your paired camera.
If no camera is found within several seconds, the LEDs flash blue and yellow briefly and the device returns to sleep.
Shutting Down
To enter deep sleep for travel or transport, hold the button until all LEDs flash in a rapid pattern (about 3 seconds). In deep sleep, only a button press will wake the device, preventing accidental wake-ups from vibration during transit.
If you are leaving your helmet at the drop zone between jumps, shutting down is optional. The device will sleep and wake automatically as needed.
Pairing
BLU2Lite automatically detects your camera brand during pairing and connects to the closest camera it finds. Simply put your camera into its Bluetooth pairing mode and put BLU2Lite into pairing mode by holding the button for 7 seconds (connection LED flashes blue, camera LED flashes yellow).
See the pairing guide for your camera:
- GoPro Pairing Guide (HERO5 through HERO13, MAX, MAX 2)
- DJI Pairing Guide (Osmo Action 3, 4, 5, 6, OSMO 360)
- Insta360 Pairing Guide (X2, X3, X4, X5, Ace, Ace Pro, Ace Pro 2)
- Sony Pairing Guide (BLE-enabled models)
To switch camera brands, simply pair with the new camera. BLU2Lite will automatically detect and adapt to the new camera type.
Battery
When BLU2Lite first wakes, a single LED color briefly indicates battery level:
- Green — Battery above 25%
- Yellow — Battery below 25%
- Red — Battery depleted, replace battery
The BLU2Lite uses a standard CR2032 coin cell battery (220mAh). To replace the battery, use a paperclip or similar tool to push out the old battery. Insert the new battery with the positive (+) side facing outward.
Battery Life Estimates
The BLU2Lite is engineered for minimal power consumption. Place the device in deep sleep during transport to maximize battery life.
| State | Estimated Duration |
|---|---|
| Deep sleep (button wake only) | 313 years |
| Deep sleep (accelerometer wake) | 7.8 years |
| Searching for camera | 1.4 days |
| Connected, standby | 11 days |
| Connected, recording | 8 days |
Mounting
Recommended placement: bottom left side of your helmet visor. This position allows the visor to open fully (the device height prevents top mounting) and positions the connection status LED toward your eyes for visibility.
This is the positioning I prefer
Be sure to give it about 1/2" or 1cm clearance from the gasket so it doesn't hit the BLU2Lite if the visor gets slammed shut.
In contrast: Julie has her BLU2 mounted too low and it's hard to see. It also is not good for the unit.
