Hi,
So I am trying to modify QGC on my Herelink to have some on screen buttons to control a Flir Duo Pro R camera, because I don’t have enough hardware buttons.
I have managed to create the UI as widget, but am stuck on how to send a Mavlink command to the vehicle. Here is what I have so far:
import QtQuick 2.4
import QtPositioning 5.2
import QtQuick.Layouts 1.2
import QtQuick.Controls 1.4
import QtQuick.Dialogs 1.2
import QtGraphicalEffects 1.0
import QGroundControl 1.0
import QGroundControl.ScreenTools 1.0
import QGroundControl.Controls 1.0
import QGroundControl.Palette 1.0
import QGroundControl.Vehicle 1.0
import QGroundControl.Controllers 1.0
import QGroundControl.FactSystem 1.0
import QGroundControl.FactControls 1.0
/// Flir page for controlling a Duo Pro R
Column {
width: pageWidth
spacing: ScreenTools.defaultFontPixelHeight * 0.25
property var _activeVehicle: QGroundControl.multiVehicleManager.activeVehicle
GridLayout {
columns: 2
columnSpacing: ScreenTools.defaultFontPixelWidth * 2
rowSpacing: ScreenTools.defaultFontPixelHeight
anchors.horizontalCenter: parent.horizontalCenter
QGCLabel {
text: qsTr("Camera Mode")
}
QGCComboBox {
model: ["IR", "RGB", "PIP"]
onActivated: {
//move servo via MAVLINK
}
}
QGCLabel {
text: qsTr("Photo/Video")
}
QGCSwitch {
id: videoMode
onCheckedChanged: {
if (checked) {
//move servo
} else {
//move servo the other way
}
}
}
QGCLabel {
text: qsTr("REC")
}
QGCButton {
text: "Test"
onClicked: QGroundControl.vehicle.sendCommand(_activeVehicle, //Component to send to
183, //MAV_CMD to send 183:MAV_CMD_DO_SET_SERVO
true, //showError
11, //servo instance
1500) //servo value in us
}
}
}
How can I send a mavlink command to the current active vehicle from qml? I found the function “Q_INVOKABLE void sendCommand(…)” in Vehicle.h but don’t know how to call it. I get the error “TypeError: Cannot call method ‘sendCommand’ of undefined” in the QGC console. Can anyone help me out?
@AltitudeDavid,
You need to call sendCommand method on _activeVehicle variable.
onClicked:
_activeVehicle.sendCommand(...)

Hello
I have the same Problem,
1-can you tell me in wish file in QGroundControl source github code you add this qml script? and can send to me the last version code?
2- and after adding, should I add another think in other files?
Thank you very much for repliying.
Hi,
Check the code here: GitHub - Hasi123/qgroundcontrol-herelink
Have not modified it since then.
Hello,
I encountered an error while running the QGC code. This is my first experience with QT Android development applications.

Any help pleqse?
@AltitudeDavid
great info !! What is the version of the QGC on that Github link
Not sure, 3.6 or 4.0. Quite an old one, but CubePilot also hasn´t updated it in their GitHub repo.
thank you for the feedback. What is the issue in updating the QGC on Herelink…Are there no developers to assist
No idea, ask CubePilot on GitHub. I forked my repo from there
