The rover communicates via two way Iridium, LoRa, GSM and Bluetooth. All data received from the rover is sent to the Ground Base Station. This is a service running on a server accepting various structured data coming in through the internet. The Ground Station also provides a public live tracking website.
Ground station must be able to subscribe to devices registered to the staging.thethingsnetwork.org infrastructure. A device can be subscribed to using MQTT. Using this protocol is possible to send data to the device, but also to receive it. Sending data to the device is asynchronous in its nature.
