以下是一个基于STM32标准外设库和ESP8266的WiFi模块连接Android Studio的示例代码:
```

#include <stdio.h>
#include <string.h>
#define SSID "your_wifi_ssid" // WiFi SSID

}
void ESP8266_Init(void)

在Android Studio中,您可以使用Socket类来连接服务器并发送数据。以下是一个基于Java的示例代码:
```
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.Socket;
public class MainActivity extends AppCompatActivity {
private static final String SERVER_IP = "your_server_ip_address";
private static final int SERVER_PORT = your_server_port_number;
private BufferedReader reader;
private PrintWriter writer;
private EditText editText;
private Button sendButton;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
editText = findViewById(R.id.editText);
sendButton = findViewById(R.id.sendButton);
// 连接服务器
new Thread(new Runnable() {
@Override
public void run() {
try {
Socket socket = new Socket(SERVER_IP, SERVER_PORT);
reader = new BufferedReader(new InputStreamReader(socket.getInputStream()));
writer = new PrintWriter(socket.getOutputStream(), true);
} catch (IOException e) {
e.printStackTrace();
}
}
}).start();
// 发送数据
sendButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String data = editText.getText().toString();
writer.println(data);
}
});
}
}
```
这只是一个简单的示例代码,您需要根据自己的实际需求进行修改。
