DataHub provides a status LED on its top cover that allows you to know the status of the GPS feed, internet connectivity, and if you have position reports stored on the device that have not yet been sent to PredictWind.
There are a total of 3 LEDs, blue, orange, and green.
The blue LED is illuminated to show that you have power to the DataHub.
The orange and green LEDs serve multiple purposes to display both GPS status, internet connectivity, and tracking spool state (positions waiting to be sent).
Invalid GPS
The orange and green LED will blink rapidly in alternating succession when there is invalid or NO GPS data. Fast alternating orange/green LEDs means we have no GPS position from your NMEA or built in GPS antenna, so the DataHub will not be able to send tracking position reports to PredictWind no matter the state of the internet connection.

No Internet
With a valid GPS position, a no internet connectivity issue is displayed by a slow blinking orange LED.
The orange LED blinks once every 3 seconds when there is no active internet connection. (This is normal when connected to the Iridium GO exec )
If you are connected to the Iridium GO exec check this article to make sure you are connected.
Spooled Position Reports
With valid GPS positions, a slowly blinking green LED indicates that position reports have been sampled but not sent to PredictWind for processing. Normally you see slow blinking green along with slow blinking orange. The blinking orange LED indicates no internet, while the slow blinking green LED means that you have position reports queued but not sent.
When an internet connection becomes available, the DataHub will automatically send the position reports and the green LED will be turned off.
