Aeroscope has a "Deep Sleep" mode that can be accessed by tapping on the "Deep Sleep" button under the settings menu. Aeroscope will also automatically go into this mode if the battery is depleted too far.
In this mode, Aeroscope will be in its lowest power state and won't advertise over Bluetooth. The only way to "wake up" from this mode is to push the button or plug in a charger. If Aeroscope's battery voltage is high enough, the button will flash green once. If the battery is depleted it will flash yellow once and go back to sleep.
We envision this deep sleep mode being used when taking Aeroscope on an Airplane, or shipping Aeroscope in the mail, or any other time where you wouldn't want Aeroscope to broadcast over Bluetooth. Keep in mind that putting Aeroscope in this mode will cause the DC calibration settings to be lost. You will have to run the calibration routine when it wakes back up.
