要在ESP32上进行TCP数据传输,您需要使用以下步骤:
1. 包含ESP32的WiFi库和TCP库。
```c++
#include <WiFi.h>
#include <WiFiClient.h>
```
2. 连接到WiFi网络。
```c++
const char* ssid = "your_SSID";
const char* password = "your_PASSWORD";
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(1000);
Serial.println("Connecting to WiFi...");
}
Serial.println("Connected to WiFi");
```
3. 创建TCP客户端并连接到服务器。
```c++
WiFiClient client;
const int port = 80;
const char* server = "your_SERVER_IP";
if (!client.connect(server, port)) {
Serial.println("Connection failed");
return;
}
Serial.println("Connected to server");
```
4. 发送数据到服务器。
```c++
client.print("Hello server");
```
5. 从服务器接收数据。
```c++
while (client.available()) {
String line = client.readStringUntil('\r');
Serial.println(line);
}
```
6. 关闭连接。
```c++
client.stop();
```
完整的示例代码如下:
```c++
#include <WiFi.h>
#include <WiFiClient.h>
const char* ssid = "your_SSID";
const char* password = "your_PASSWORD";
const int port = 80;
const char* server = "your_SERVER_IP";
void setup() {
Serial.begin(9600);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(1000);
Serial.println("Connecting to WiFi...");
}
Serial.println("Connected to WiFi");
WiFiClient client;
if (!client.connect(server, port)) {
Serial.println("Connection failed");
return;
}
Serial.println("Connected to server");
client.print("Hello server");
while (client.available()) {
String line = client.readStringUntil('\r');
Serial.println(line);
}
client.stop();
}
void loop() {
}
```
