The Arrowhead mesh radio system can take between 45-55 seconds to establish a connection after both the controller, backpack, and aircraft have been powered. If after this time, there is still no connection, this can be caused by:
| Possible sources | Causes | What to inspect |
|---|---|---|
| Comm Link | The Arrowhead connects to the software through a comm link that is pre-set during the production process. Departments that have more than one system on the same controller will need to cycle the comm link in “Application Settings” when changing drones. | Follow the steps in the images below. After following these steps, back out to the main screen of QGC, you should be connected to the aircraft now. |
| Radio Backpack | The Radio Backpack on the Arrowhead controller houses the modem and all necessary hardware to establish the connection. | If powering the Asus ROG Ally through the backpack, plug the backpack into the ROG Ally FIRST, then connect external power. You should hear the fan spin up and a USB connection made with the controller. ENSURE THE ANTENNA ARE ATTACHED BEFORE POWERING THE BACKPACK. |
| Modem Damage | The modems on the aircraft can sustain damage if the controller backpack is powered on without the antenna connected. This can severely reduce the range of the aircraft and break the connection entirely. | If the backpack is powered for an extended period without antenna mounted, damage can be sustained to the controller modem. This will severely reduce range or even break the connection entirely. This will require repair in our facility. |
