Ok, I'm really confused here.
I have tried a D1 Mini and a NodeMCU and can't get either of them to connect to my Wifi.
The D1 was part of another (working) project and i grabbed it for this thinking i was doing something wrong with the Node.
No matter what I do, I can't seem to get them connecting to my Wifi.
I'm using the built in examples from the ESP8266 board library and they just sit on connecting.
This is an example
/*
* This sketch demonstrates how to set up a simple HTTP-like server.
* The server will set a GPIO pin depending on the request
* http://server_ip/gpio/0 will set the GPIO2 low,
* http://server_ip/gpio/1 will set the GPIO2 high
* server_ip is the IP address of the ESP8266 module, will be
* printed to Serial when the module is connected.
*/
#include <ESP8266WiFi.h>
const char* ssid = "-------";
const char* password = "------";
// Create an instance of the server
// specify the port to listen on as an argument
WiFiServer server(80);
void setup() {
Serial.begin(115200);
delay(10);
// prepare GPIO2
pinMode(2, OUTPUT);
digitalWrite(2, 0);
// Connect to 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");
// Start the server
server.begin();
Serial.println("Server started");
// Print the IP address
Serial.println(WiFi.localIP());
}
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 req = client.readStringUntil('\r');
Serial.println(req);
client.flush();
// Match the request
int val;
if (req.indexOf("/gpio/0") != -1)
val = 0;
else if (req.indexOf("/gpio/1") != -1)
val = 1;
else {
Serial.println("invalid request");
client.stop();
return;
}
// Set GPIO2 according to the request
digitalWrite(2, val);
client.flush();
// Prepare the response
String s = "HTTP/1.1 200 OK\r\nContent-Type: text/html\r\n\r\n<!DOCTYPE HTML>\r\n<html>\r\nGPIO is now ";
s += (val)?"high":"low";
s += "</html>\n";
// Send the response to the client
client.print(s);
delay(1);
Serial.println("Client disonnected");
// The client will actually be disconnected
// when the function returns and 'client' object is detroyed
}
I do not alter it at all, just input my SSID and Password.
I have also tried hot-spotting my phone, and that doesn't work either.
However, I am able to set the D1 up as an AP and connect to it using my phone, so at-least I know the hardware looks ok.
I was on version 2.4.0 of the 8266 Library. I upgraded to 2.4.2 when I had issues. I have now downgraded to 2.3.0 in the off chance it changed something.
I have even set up a separate SSID that is 2.4Ghz only and that hasn't helped.
Everything else it connecting to my wifi fine, so i don't think it's that. (2 phones, N-Switch, notebook computer, Echo, etc)
I'm within 3m of the AP (It's a Meraki AP mounted on the ceiling) and have LOS to it (not that it should matter).
Any ideas?
