3. Connecting Botlink XRD2 to Autopilot
Connecting the Botlink XRD2 system to your existing autopilot is quick and simple. The XRD2
will easily integrate with MAVLink based autopilots, such as Pixhawk, Pixhawk 2, and ArduPilot
Mega, running PX4 or APM firmware.
4. Connecting Botlink Relay to Ground Control Software
Botlink Relay can be connected to QGroundControl, Mission Planner, and other compatible
flight control software. Additionally, Botlink Relay SDK is available for custom integrations
4.1 Connecting Botlink Relay to QGroundControl
4.1.1 UDP Connection
UDP set up is recommended, and a little bit simpler since you don’t have to configure anything in
QGroundControl. The default UDP port in QGroundControl can automatically connect to Botlink Relay,
but you do have to set this up in a specific order. First, power on the drone (which includes XRD2 and
flight controller). Second, configure Botlink Relay (shown below), and press the blue start button.
QGroundControl should connect as soon as the Relay app shows the connection.
