The flashing green LED indicates that the Bora band is switched off. This is activated by a long press on the push button (3 seconds).
If you want to turn it on, a simple and short press must be done.
If, in spite of a single press, the Bora band displays a flashing green color, it means that it is in the process of being turned off due to a lack of battery. Please put it on charge until the battery is fully charged. When the battery is fully charged, the Bora band will no longer flash white, so you can turn it on again.
