What does it do?
It allows for the beacon to go into a hibernation mode (deep sleep) when not in use.
Thus lowering power consumption and extending battery life.
Simultaneously it will help older Android phones (often Samsung phones) connect better.
It will do so by transmitting signals at maximum speed and power for an interval of ten minutes before going back into hibernation mode.
How do I turn this on?
First, make sure that the beacon you want to put in hibernation is within close proximity to the phone and is not already in hibernation. You can confirm this by simply activating the CrewWatcher by pressing the top right toggle. If CrewWatcher activates with "Everything OK" you can proceed.
To wake your beacons from hibernation, dunk them in water for at least three seconds.
For as long as hibernation is enabled, this will be mandatory after any ten minute period of inactivity. (CrewWatcher in the app turned off and gray)
Make sure that the sensing pins on the bottom are fully submerged.
Alternatively, you can use a piece of conductive wire to connect the sensing pins for at least three seconds.
If you've never used your beacons before, the activation period is not three but ten seconds.
Quick tip: Always try to use a large enough container of water so the beacon can float horizontally. Submerging your beacon vertically in a glass can cause air bubbles to form around the sensing pins, much like a diving bell. This will isolate them from the water and not sense the submersion.
