我有2个ESP8266，我想连接到具有不同静态地址的同一网络。一个完美的工作。当我添加另一个时，两个都停止工作。在阅读了更多关于https://github.com/knolleary/pubsubclient/issues/259之后，我认为这是客户端ID的问题，但我不知道如何解决它。这是我正在使用的代码：
#include <ESP8266WiFi.h>
const char* ssid = "ESP Test";
const char* password = "88888888";
; //
WiFiServer server(80);
void setup() {
Serial.begin(115200);
delay(10);
pinMode(0, OUTPUT);
pinMode(2, OUTPUT);
pinMode(0, OUTPUT);
pinMode(13, OUTPUT);
digitalWrite(0, LOW);
digitalWrite(2, LOW);
digitalWrite(0, LOW);
digitalWrite(13, LOW);
// Connect to WiFi network
Serial.println();
Serial.println();
Serial.print("Connecting to ");
Serial.println(ssid);
WiFi.begin(ssid, password);
IPAddress ip(192,168,5,199);
IPAddress gateway(192,168,5,1);
IPAddress subnet(255,255,255,0);
WiFi.config(ip, gateway, subnet);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("");
Serial.println("WiFi connected");
// Start the server
server.begin();
Serial.println("Server started");
// Print the IP address
Serial.print("Use this URL to connect: ");
Serial.print("http://");
Serial.print(WiFi.localIP());
Serial.println("/");
}
void loop() {
// Check if a client has connected
WiFiClient client = server.available();
if (!client) {
return;
}
// Wait until the client sends some data
Serial.println("new client");
while(!client.available()){
delay(1);
}
// Read the first line of the request
String request = client.readStringUntil('\r');
Serial.println(request);
client.flush();
// Match the request
if (request.indexOf("/light1on") > 0) {
digitalWrite(0, HIGH);
}
if (request.indexOf("/light1off") >0) {
digitalWrite(0, LOW);
}
if (request.indexOf("/light2on") > 0) {
digitalWrite(2, HIGH);
}
if (request.indexOf("/light2off") >0) {
digitalWrite(2, LOW);
}
if (request.indexOf("/light3on") >0) {
digitalWrite(0, HIGH);
}
if (request.indexOf("/light3off") > 0) {
digitalWrite(0, LOW);
}
if (request.indexOf("/light4on") > 0) {
digitalWrite(13, HIGH);
}
if (request.indexOf("/light4off") > 0) {
digitalWrite(13, LOW);
}
// Set ledPin according to the request
//digitalWrite(ledPin, value);
// Return the response
client.println("HTTP/1.1 200 OK");
client.println("Content-Type: text/html");
client.println(""); // do not forget this one
client.println("<!DOCTYPE HTML>");
client.println("<html>");
client.println("<head>");
client.println("<meta name='apple-mobile-web-app-capable' content='yes' />");
client.println("<meta name='apple-mobile-web-app-status-bar-style' content='black-translucent' />");
client.println("</head>");
client.println("<body bgcolor = \"#f7e6ec\">");
client.println("<hr/><hr>");

由于我无法添加评论，我会将此作为答案发布。请注意，这主要是猜测
我只是想知道mac地址是否存在问题？您是否检查过两台设备以确保它们具有唯一的MAC地址？
如果他们有相同的地址，这可能是问题。 If found this article可能有所帮助。我没试过，但作者展示了如何更改esp8266设备上的mac地址。
正如我所说，猜测:)
