ESP07 Webserver not reachable
Posted: Wed Aug 26, 2020 10:35 amHello everyone,
I've a problem to reach the webserver.. I tried out all examples I found in the IDE and a lot of stuff from the internet. However, I can flash the ESP07 with the FDTI programmer without problems. The sketch is starting as well. It says that the esp is connected to the router, but it doesn't show me anything (via IP adress as well as via mDNS adress) and it's not seeing the client.
That's my example code:
And this is my serial monitor output:
Best regards,
Florian
I've a problem to reach the webserver.. I tried out all examples I found in the IDE and a lot of stuff from the internet. However, I can flash the ESP07 with the FDTI programmer without problems. The sketch is starting as well. It says that the esp is connected to the router, but it doesn't show me anything (via IP adress as well as via mDNS adress) and it's not seeing the client.
That's my example code:
Code: Select all
#include <ESP8266WiFi.h>
#include <ESP8266mDNS.h>
#include <WiFiClient.h>
#ifndef STASSID
#define STASSID "WLAN-8YZG83"
#define STAPSK "*********"
#endif
const char* ssid = STASSID;
const char* password = STAPSK;
// TCP server at port 80 will respond to HTTP requests
WiFiServer server(80);
void setup(void) {
Serial.begin(115200);
// Connect to WiFi network
WiFi.mode(WIFI_STA);
WiFi.begin(ssid, password);
Serial.println("");
// Wait for connection
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("");
Serial.print("Connected to ");
Serial.println(ssid);
Serial.print("IP address: ");
Serial.println(WiFi.localIP());
// Set up mDNS responder:
// - first argument is the domain name, in this example
// the fully-qualified domain name is "esp8266.local"
// - second argument is the IP address to advertise
// we send our IP address on the WiFi network
if (!MDNS.begin("esp8266")) {
Serial.println("Error setting up MDNS responder!");
while (1) {
delay(1000);
}
}
Serial.println("mDNS responder started");
// Start TCP (HTTP) server
server.begin();
Serial.println("TCP server started");
// Add service to MDNS-SD
MDNS.addService("http", "tcp", 80);
}
void loop(void) {
MDNS.update();
// Check if a client has connected
WiFiClient client = server.available();
if (!client) {
return;
}
Serial.println("");
Serial.println("New client");
// Wait for data from client to become available
while (client.connected() && !client.available()) {
delay(1);
}
// Read the first line of HTTP request
String req = client.readStringUntil('\r');
// First line of HTTP request looks like "GET /path HTTP/1.1"
// Retrieve the "/path" part by finding the spaces
int addr_start = req.indexOf(' ');
int addr_end = req.indexOf(' ', addr_start + 1);
if (addr_start == -1 || addr_end == -1) {
Serial.print("Invalid request: ");
Serial.println(req);
return;
}
req = req.substring(addr_start + 1, addr_end);
Serial.print("Request: ");
Serial.println(req);
client.flush();
String s;
if (req == "/") {
IPAddress ip = WiFi.localIP();
String ipStr = String(ip[0]) + '.' + String(ip[1]) + '.' + String(ip[2]) + '.' + String(ip[3]);
s = "HTTP/1.1 200 OK\r\nContent-Type: text/html\r\n\r\n<!DOCTYPE HTML>\r\n<html>Hello from ESP8266 at ";
s += ipStr;
s += "</html>\r\n\r\n";
Serial.println("Sending 200");
} else {
s = "HTTP/1.1 404 Not Found\r\n\r\n";
Serial.println("Sending 404");
}
client.print(s);
Serial.println("Done with client");
}
And this is my serial monitor output:
Code: Select all
.......
Connected to WLAN-8YZG83
IP address: 192.168.2.113
mDNS responder started
TCP server started
