By default, Dot's Bluetooth is disabled. It does not emit continuously.
To connect to the application, the Dot must be activated(by tapping it several times). Its activation is confirmed by the lighting of the green LED.
This activates the Bluetooth and allows the connection to the application (modification of the parameters or download of the sleep data).
Note: since a software update (from V1.81), the Dot will be activated automatically 30 minutes before and 30 minutes after the end of the monitoring time in order to facilitate the download of your data. Outside this period, it is necessary to manually activate the DOT (tap two or three times on it) to "wake it up" and to be able to download your data.
Dot's Bluetooth turns off after a few minutes
