qt设置WiFi mesh 的根节点代码

以下是Qt设置WiFi mesh根节点的代码示例：

#include <QCoreApplication>
#include <QProcess>

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    QProcess process;
    process.start("nmcli", QStringList() << "connection" << "add" << "type" << "wifi" << "ifname" << "wlan0" << "mode" << "mesh" << "ssid" << "my_mesh_network");
    process.waitForFinished();
    process.start("nmcli", QStringList() << "connection" << "modify" << "my_mesh_network" << "802-11-wireless.meshid" << "my_mesh_network" << "802-11-wireless.band" << "bg");
    process.waitForFinished();
    process.start("nmcli", QStringList() << "connection" << "up" << "my_mesh_network");
    process.waitForFinished();

    return a.exec();
}

在此示例中，使用`QProcess`类运行`nmcli`命令行工具。`nmcli`是NetworkManager的命令行工具，用于管理网络连接。`connection add`命令创建一个新的WiFi mesh网络连接，`connection modify`命令设置网络连接的属性，例如mesh id和band，`connection up`命令启动网络连接。请根据您的具体需求修改示例代码。
