Qt中实现Wi-Fi Mesh需要使用QNetworkConfigurationManager和QNetworkSession类,以及QAbstractSocket和QDataStream类进行数据传输。以下是一个简单的Wi-Fi Mesh示例:
1. 初始化Wi-Fi Mesh网络:
```
QNetworkConfigurationManager manager;
QList<QNetworkConfiguration> configurations = manager.allConfigurations(QNetworkConfiguration::Discovered);
foreach(QNetworkConfiguration config, configurations) {
if(config.bearerType() == QNetworkConfiguration::BearerWLAN) {
QNetworkSession session(config);
session.open();
break;
}
}
```
2. 创建一个Mesh节点:
```
QTcpServer server;
if(server.listen(QHostAddress::Any, 9999)) {
connect(&server, &QTcpServer::newConnection, this, &MyClass::onNewConnection);
}
```
3. 处理新连接:
```
void MyClass::onNewConnection()
{
QTcpSocket *clientSocket = server.nextPendingConnection();
connect(clientSocket, &QTcpSocket::readyRead, this, &MyClass::onReadyRead);
connect(clientSocket, &QTcpSocket::disconnected, this, &MyClass::onDisconnected);
sockets << clientSocket;
}
```
4. 处理数据传输:
```
void MyClass::onReadyRead()
{
QTcpSocket *socket = static_cast<QTcpSocket *>(sender());
QDataStream in(socket);
while(!in.atEnd()) {
QByteArray data;
in >> data;
// 处理接收到的数据
}
}
```
5. 发送数据:
```
void MyClass::sendData(QByteArray data)
{
foreach(QTcpSocket *socket, sockets) {
QDataStream out(socket);
out << data;
}
}
```
这是一个简单的Wi-Fi Mesh示例,你可以根据自己的需求进行修改和扩展。
