Hi all,
I got an Adafruit Huzzah ESP8266 breakout board this week and I'm trying to connect it to my wifi.
Since I's like to stick to the Arduino IDE, I thought I'd post my problem here.
I got it connected, I can program sketches into it and I can get a list of available networks. I just can not get it connected to my own wifi. I got a cafe across the street with on open wifi network (no password), I can connect to that without problems.
I used this code from Using Arduino IDE | Adafruit HUZZAH ESP8266 breakout | Adafruit Learning System
/*
* Simple HTTP get webclient test
*/
#include <ESP8266WiFi.h>
const char* ssid = "Cafe SSID";
const char* password = "";
const char* host = "www.adafruit.com";
void setup() {
Serial.begin(115200);
delay(100);
// We start by connecting to a WiFi network
Serial.println();
Serial.println();
Serial.print("Connecting to ");
Serial.println(ssid);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("");
Serial.println("WiFi connected");
Serial.println("IP address: ");
Serial.println(WiFi.localIP());
}
int value = 0;
void loop() {
delay(5000);
++value;
Serial.print("connecting to ");
Serial.println(host);
// Use WiFiClient class to create TCP connections
WiFiClient client;
const int httpPort = 80;
if (!client.connect(host, httpPort)) {
Serial.println("connection failed");
return;
}
// We now create a URI for the request
String url = "/testwifi/index.html";
Serial.print("Requesting URL: ");
Serial.println(url);
// This will send the request to the server
client.print(String("GET ") + url + " HTTP/1.1\r\n" +
"Host: " + host + "\r\n" +
"Connection: close\r\n\r\n");
delay(500);
// Read all the lines of the reply from server and print them to Serial
while(client.available()){
String line = client.readStringUntil('\r');
Serial.print(line);
}
Serial.println();
Serial.println("closing connection");
}
I have a hunch that my router setting might be the issue.
My setup:
- Router: WRT54-GL
- Running: Tomato Firmware 1.28.0005 124 ND SD-VPN
When I use my own SSID in the code above it just stays in this loop:
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Is there any way of further diagnosing the problem using the Arduino IDE ?
Thanks !
