On the VOXL, the LTE connection will need to be configured. Instructions here to connect to the network. In order for the QGroundControl station to find the VOXL connected over LTE, the VOXL’s IP address needs to be reachable. There are two methods:
- Static IP obtained through cellular carrier
- Use a cloud man-in-the-middle setup with VPN
To connect the QGroundControl station to the VOXL, it just needs an internet connection. This could be from your facility’s Wi-Fi network. If you’re going out to the field , an internet internet connection is needed through a cellular dongle.
RC Control for safety pilot
Often a backup R/C controller such as Spektrum or Futaba are used for safety. The range of the R/C controller is limited where the range of LTE is significantly further, as far as the network will take you. PX4’s lost-link behaviour needs to be configured through QGroundControl to handle lost safety R/C.
Joystick Control over LTE
Joystick control can be routed through QGroundControl if joysticks are connected to the same computing device that is running QGroundControl.
Alternate Flight Controllers
Other flight controllers that use MAVLink, such as ArduPilot, should work but are not well tested by ModalAI
