Detailed Description

The SerialPortDevice component provides identifying and descriptive information about a single currently-connected serial port device. This is useful for confirming that the correct type of serial port device is being used for your app's needs.

This component inherits the properties and methods from the Device component, allowing for it to use the readData and writeData properties to send and receive data between your app and the device.

This code sample demonstrates usage of the SerialPortDevice component, displaying in a list view properties read from a device detected by DeviceDiscoveryAgent.

Item {
        property DeviceListModel deviceListModel: discoveryAgent.devices
        property SerialPortDevice currentDevice

        ColumnLayout {
                anchors.fill: parent
                anchors.margins: 10

                ComboBox {
                        id: comboBox
                        Layout.fillWidth: true
                        model: deviceListModel
                        textRole: "name"
                        onCurrentTextChanged: currentDevice = deviceListModel.get(currentIndex)

                ListView {
                        id: listView
                        property var fields: [
                        Layout.fillWidth: true
                        Layout.fillHeight: true
                        model: currentDevice != null ? fields : 0
                        delegate: Text { text: "%1: %2".arg(modelData).arg(currentDevice[modelData]) }

        DeviceDiscoveryAgent {
                id: discoveryAgent

        Connections {
                target: deviceListModel
                onCountChanged: if (comboBox.currentIndex == -1 && deviceListModel.count > 0) { comboBox.currentIndex = 0; }

        Component.onCompleted: discoveryAgent.start()
