BLU2Lite User Manual

The BLU2Lite Indicator is intuitive to use and works similarly to Hypoxic's products of past years. Since this device is battery powered and uses BLE (Bluetooth Low Energy) for connectivity, some newer status modes exist.

Device Overview

  • Device Status Used mainly for setup, this LED is used when pairing, connecting, and shows the battery level when waking up. 
  • Multi-Function Button This button is used to power down the device, pair to a new camera, and enter a firmware update mode if necessary. 
  • Connection Status This Blue LED shows if the BLU2Lite is searching for a paired camera, the connection state, or if the unit is attempting to pair to a camera. 
  • Camera Status The three LEDs show the status of the camera once connected. 

Camera Status

Once paired, connected, and awake the indicators are intuitive.

 BLU2Lite States

  • Sleep BLU2 will awake with a slight shake.
  • Searching BLU2 will search for several seconds for a paired camera before going back to sleep. 
  • Connected BLU2 will stay on until camera is turns off.
  • Deep Sleep BLU2 requires a button press to wake it up.

Waking Up

Since the BLU2Lite is battery powered, much care has been given to minimizing the power draw while providing a reliable and responsive product. An accelerometer within the BLU2Lite waits for high G's to turn on the device and start searching for the camera. A slight shake or tilt on your helmet is generally enough to wake up the device from sleep. 

Once awake, it will spend a couple seconds searching for a camera before going back to sleep. A quick blue and yellow led blink signifies the BLU2Lite is searching for a camera. 

Shutting Down

If the BLU2Lite is going to be traveling or moving around for a few hours, it's recommended to place the device in a deep sleep. To perform this, simply hold the button until you see Disco-lights and then release. Disco-lights is all the LEDs flashing. This stellar pattern occurs after holding down the button for 3 seconds.  

If you leave your helmet at the DZ, there is no need to turn it off at the end of the weekend. 

Pairing

Pairing is the method to connect the BLU2Lite to your GoPro Camera. During the pairing sequence, the camera also sets the default mode. Therefore the first step is critical.

  1. Turn on the GoPro Camera and ensure the correct mode is active. For most people this will be Video Mode or Timelapse Photo Mode. 
  2. On the GoPro, pull down from the top and choose Connections->Connect New Device->GoPro App or GoPro QuikApp. There is a slight difference between supported cameras so follow the below table if you are having difficulty.
  3. If your BLU2Lite is straight from the factory, the camera status should be flashing yellow and the connection status led flashing blue. This signifies the BLU2Lite is in pairing mode. If not, hold down the button for seven seconds until the connection status flashes blue and camera status flashes yellow. Then immediately release the button. 
  4. The camera should now pair. If the BLU2Lite goes to sleep during the paring process, simply shake it to wake it up.

Battery Level

When the BLU2Lite first wakes up, it first blinks a single led color. This color denotes the battery level of the BLU2Lite. 

Camera Status LED Battery State
Green >25%
Yellow <25%
Red Must be charged

 

The battery is an easily sourced CR2032. Use a paperclip to QUICKLY push out the old battery. Positive (+) side is facing us here. 

BLU2Lite Replacing Battery

 

Mounting

Once you've successfully paired the BLU2Lite to your camera now it's time to mount it on your helmet. We recommend the bottom left side of your visor. These are the two reasons:

  • Allows the visor to fully open up. The height of the BLU2Lite will hit the helmet if mounted too far towards the top. 
  • The connection status LED is mounted towards your eyes. 

Updating

The BLU2Lite can be updated via an Android or iPhone app that will be released in the future. This may allow features such as configurability and working with other manufacturer's cameras.

Troubleshooting

  • BLU2Lite takes a long time to connect using QuickStart / One-button-mode. 
    Some GoPro cameras use all their processing power when they first turn on and immediately start recording. The camera itself is not fully booted up in this state and it takes a while for the BLE subsystem to initialize. Therefore this is a limitation of the camera.
    It's suggested to turn the camera on standby when using the BLU2Lite and press record when ready to exit for the best user experience.
  • IMPORTANT The first connect every day will also take the longest on some cameras. (See below)
  • It takes a long time to connect in the morning. 
    The GoPro goes into a deep sleep after 8 hours of non-use. This is typical and it is suggested to check your setup before loading in the plane each morning.
  • BLU2Lite Blinks red and immediately turns off or does not turn on at all.
    Battery is dead, please recharge before use.
  • The GoPro HERO5 or HERO5 Session battery dies quicker when I use BLU2Lite.
    Unlike newer models, these old models kept their WiFi transmitter on when only BLE is needed. This will reduce the longevity slightly. Other cameras will not see much decrease in battery life expectancy. 
  • GoPro Constantly reboots
    There is a bug with some versions of the GoPro firmware that will get the camera into an endless reboot cycle. If you get this error, you'll have to put a factory_reset.txt file on your card to reset the camera's settings. 
    This post can help.

Power Usage

Great care has been taken to provide the most reliable indicator that does not interfere with the normal operation of your camera. Therefore, great pains have been taken to minimize the power usage of both the camera and the BLU2Lite. 

We painstakingly engineered this battery product to last for months of typical use. We recommend that the device is placed in to deep sleep when being transported. This prevents that "searching for camera" power usage which uses the most power.
The GoPro HERO5 and GoPro HERO5 Session cameras will see quicker battery drain.
