The LED always blinks twice after shortly pressing the button on the front of the GPS tracker.
FIRST BLINK: When it is green, it means that there is a GSM connection to the Tractive server. In case it is red, there is no GSM connection.
SECOND BLINK: If the second blink is green, there is GPS available, if it is red, there is no GPS available.
The LED also blinks when the GPS tracker is in Live Tracking mode and in case of very low battery status.
