we might have to call you Mr. ESP from now on.

I'm far from been perfect, so I prefer been called ESPBoy ...

- Mon Oct 05, 2015 3:00 pm #30583 I mean to say, with the newest code and my prior code, the AP server does not start up, also the LED stays lit at all times.

Here is the current code on the ESP-01 that includes your code:

Code: Select all/* Create a WiFi access point */

#include <ESP8266WiFi.h>
#include <WiFiClient.h>
#include <ESP8266WebServer.h>
extern "C" {
#include "user_interface.h"
}
#define WIFI_MODE_AP

/* Set these to your desired credentials. */
const char *ssid = "Proximity Trigger 1";
const char *password = "thereisnospoon";
//Reference station counter as "devices"
unsigned char devices;
// boolean ledState = false;
int alreadyBlinked = 0;
unsigned int prevMillis = 0;



ESP8266WebServer server(80);

void handleRoot() {

}

void setup() {
  delay(1000);
  Serial.begin(115200);
  Serial.println();
  pinMode(2, OUTPUT);
  digitalWrite(2, LOW);
  //Serial.print("Configuring access point...");
  /* You can remove the password parameter if you want the AP to be open. */
  WiFi.softAP(ssid, password);

  IPAddress myIP = WiFi.softAPIP();
  Serial.print("AP IP address: ");
  Serial.println(myIP);
  server.on("/", handleRoot);
  server.begin();
 
 
   }

void loop() {
  devices = wifi_softap_get_station_num();
  if (devices == 0) {
    alreadyBlinked = 0;
  }
  else if (alreadyBlinked == 0) {           
    digitalWrite(2, HIGH);
    prevMillis = millis();
    alreadyBlinked = 1;
  }
  if (alreadyBlinked > 0 && (millis() - prevMillis) > 1000) {
    digitalWrite(2, LOW);
  }
  server.handleClient();
}
 

   

 

I apologize for being so ignorant about arduino programming, and thank you for your time helping so far.
I have read somewhere that some LEDs confuse the ESP-01, perhaps that may have something to do with it.
I hope we can get this project working!

First, it seems that wifi_softap_get_station_num() doesn't like to be called too often, so I moved it inside the 1 second If. Second, it seems that wifi_softap_get_station_num() is not coherent with real number of connections, after disconnect, it was still at 1, so I've decided to use wifi_softap_get_station_info() instead and counting the number of client myself. It is a bit better, but it still buggy too. But maybe you can try to see if it is working for you.

Code: Select allvoid loop() {
  if ((millis() - prevMillis) > 1000) {
    prevMillis = millis();
    devices = 0;
    struct station_info *stat_info = wifi_softap_get_station_info();
    while (stat_info != NULL) {
      stat_info = STAILQ_NEXT(stat_info, next);
      devices++;
    }
    if (alreadyBlinked > 0) {
      digitalWrite(16, LOW);
      prevMillis = millis();
    }
  }
  if (devices == 0) {
    alreadyBlinked = 0;
  }
  else if (alreadyBlinked == 0) {           
    digitalWrite(16, HIGH);
    prevMillis = millis();
    alreadyBlinked = 1;
  }
  server.handleClient();
}
 

- Mon Oct 05, 2015 4:47 pm #30604 I just tested out your latest bit of code, what happens is the LED lights up immediately and stays on always, and I am not picking up an access point coming from the ESP-01.
Darn! More troubleshooting.
