The DataHub provides status LEDs on its top cover that allow you to know the status of the GPS feed, internet connectivity, and if you have GPS position reports stored on the device that have not yet been sent to PredictWind.

The DataHub has three LEDs, coloured blue, orange, and green.

The blue LED indicates that the DataHub is powered on.

The orange and green LEDs serve multiple purposes to display the GPS status, internet connectivity, and whether GPS tracking positions are in a spooled state on the DataHub waiting to be sent.

The Datahub orange and green LEDs will blink rapidly in alternating succession when there is invalid or NO GPS data. Fast alternating orange/green LEDs mean there is no GPS position from your NMEA or built-in GPS patch antenna, so the DataHub cannot send tracking position reports to PredictWind, no matter the state of the internet connection. To resolve this, see the article DataHub GPS tracking not working.

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, which is normal when connected to the Iridium GO exec.

To check if the DataHub is connected to the GO exec see the article GO exec will not connect to the DataHub.

When the DataHub is connected to the internet, the orange LED stays solidly lit.

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.
