esp32wifi无线透传

ESP32是一款低功耗、低成本的Wi-Fi和蓝牙组合芯片，它可以作为一个独立的微控制器运行。ESP32支持Wi-Fi Direct P2P，软AP和STA模式。下面是ESP32实现无线透传的步骤：

1. 首先，需要连接到Wi-Fi网络。可以使用以下代码连接到Wi-Fi：

#include <WiFi.h>

const char* ssid = "your_SSID";
const char* password = "your_PASSWORD";

void setup() {
  Serial.begin(115200);
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to WiFi...");
  }
  Serial.println("Connected to WiFi");
}

void loop() {
  // Your code here
}

2. 连接到Wi-Fi网络后，可以使用以下代码设置TCP服务器：

#include <WiFi.h>
#include <WiFiClient.h>
#include <WiFiServer.h>

const char* ssid = "your_SSID";
const char* password = "your_PASSWORD";

WiFiServer server(80);

void setup() {
  Serial.begin(115200);
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to WiFi...");
  }
  Serial.println("Connected to WiFi");

  server.begin();
}

void loop() {
  WiFiClient client = server.available();
  if (client) {
    while (client.connected()) {
      if (client.available()) {
        String request = client.readStringUntil('\r');
        Serial.println(request);
        client.println("Hello, world!");
        break;
      }
    }
    client.stop();
    Serial.println("Client disconnected");
  }
}

3. 设置TCP服务器后，可以使用以下代码设置TCP客户端：

#include <WiFi.h>
#include <WiFiClient.h>

const char* ssid = "your_SSID";
const char* password = "your_PASSWORD";
const char* host = "example.com";
int port = 80;

void setup() {
  Serial.begin(115200);
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to WiFi...");
  }
  Serial.println("Connected to WiFi");
}

void loop() {
  WiFiClient client;
  if (client.connect(host, port)) {
    Serial.println("Connected to server");
    client.println("Hello, server!");
    while (client.connected()) {
      if (client.available()) {
        String response = client.readStringUntil('\r');
        Serial.println(response);
        break;
      }
    }
    client.stop();
    Serial.println("Disconnected from server");
  } else {
    Serial.println("Connection failed");
  }
}
