One of the attractive Andruav features is that besides the built-in FPV features and multi drone tracking, is the ability to provide a telemetry over internet between your drone and your GCS. The connection uses mobile internet which means that telemetry range is unlimited.
The above video uses a multiwii board from HK with a bluetooth module. the module is connected to Andruav-Drone mobile. Andruav Drone communicates using Mobile network via Andruav server to Andruav GCS. Then I useEZ-GUI to connect using TCP to Andruav GCS mobile.
As we can see still you can make remote camera shooting and read Andruav Drone sensors independent of quadcopter multiwii board. Still you can use othe Drone-GCS and track the same quad, or you can quad other drones using the same Andruav - GCS using the many-to-many Andruav communication.
