BLU2Pro User Manual
The BLU2Pro is a rechargeable Bluetooth Low Energy (BLE) camera status indicator designed for action sports. It connects wirelessly to your camera and displays recording status, warnings, and errors through a remote LED display, giving you peace of mind that your camera is getting the shot.
BLU2Pro supports GoPro, DJI, Insta360, Canon, and Sony cameras from a single device. The camera type is detected automatically during pairing.

Quick Start Video
Device Components

- Device Status LED — Shows battery level on wake-up, pairing status, and connection progress
- Multi-Function Button — Powers the device, initiates pairing, and enables firmware update mode
- Charging Status LED — Red while charging, green when complete
- 2.5mm Accessory Input — Accepts remote trigger cables for hands-free shutter control (Canon-style pinout)
- USB-C Charging Port — Standard 5V charging
- Camera Status Display (Three LEDs) — Remote LED assembly on a flexible gooseneck, showing recording state, warnings, and errors
Camera Status Indicators
Once paired and connected, the three camera status LEDs show:
| Red — Camera is recording | |
| Blue — Camera is in standby (ready to record) | |
| Yellow flashing (with blue 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 | |
| Quick red & blue alternation — 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. Canon provides shutter feedback only (no status unless recording is started by the remote). Sony shows recording status but 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. |
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.
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
BLU2Pro 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 BLU2Pro into pairing mode by holding the button for 7 seconds (device status LED flashes green, camera status LEDs flash 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)
- Canon Pairing Guide (EOS R50 and other BLE-enabled models)
- Sony Pairing Guide (BLE-enabled models)
To switch camera brands, simply pair with the new camera. BLU2Pro will automatically detect and adapt to the new camera type.
2.5mm Accessory Input
The 2.5mm jack accepts standard 2.5mm TRS remote trigger cables. When connected to a camera, the remote trigger starts or stops recording in the camera's current mode. The jack provides independent focus and shutter control:
- Half-press (TRS ring to ground) — Activates autofocus
- Full press (TRS tip to ground) — Fires the shutter / starts or stops recording
Compatible accessories include bite switches, tongue switches, and blow switches commonly used in skydiving.
Battery
Battery level is displayed on wake-up:
- Blue device status LED + Blue camera LEDs — Battery above 25%
- Yellow on both — Battery below 25%
- Red on both — Battery depleted, recharge immediately
The BLU2Pro uses a 250mAh LiPo battery. Charging takes approximately 2 hours via USB-C. Most users only need to charge every few months.
Battery Life Estimates
| State | Current Draw | Estimated Duration |
|---|---|---|
| Deep sleep (button wake only) | 0.003 mA | ~3,400 days |
| Deep sleep (accelerometer wake) | 0.006 mA | ~1,600 days |
| Searching for camera | 6.4-7.5 mA | ~1.3-1.5 days |
| Connected, standby | 1.5-1.7 mA | ~5.9 days |
| Connected, recording | 1.7 mA | ~5.7 days |
Mounting
Main Unit (External)
Mount the main unit to the outside of your helmet using the included VHB tape. Align toward the outside edge of the helmet to minimize snag hazards.
Be sure to remove the FCC sticker from the bottom of your unit first.
Main Unit (Internal)
On loose-fitting helmets, the main unit fits in unused audible altimeter pockets.
LED Display
Route the display cord under helmet padding to your forehead area for visibility. The flexible gooseneck holds the LEDs in position.
Do not mount the camera status display to your articulating ringsight. This will cause premature wear and is not covered by warranty.
Firmware Updates
Firmware updates add new camera support, features, and bug fixes. Update using the free app on your phone:
