ESP8266-01 WiFi Relay - STA and AP mode problem
Posted: Tue Dec 26, 2017 2:26 pmHi, I try to run this simple code on ESP-01 but I can not connect to any access point.
I got the output like:
I tried many ways of doing it. I can not setup STA mode nor AP mode like the whole ESP's Wifi module was broken or stop working. When I setup AP mode, then when I try to connect to it I got connecting -> enter password -> disconnected.
I am sure that this module worked once, but after another firmware update it stopped working. I'm not sure if I should clear flash, but I tried WIFI_OFF, ESP.eraseConfig(); ESP.restart ESP.reset() etc.
This is my setup. I use Arduino IDE but I installed also Espressif libraries:
I use this code to enable AP mode. It starts AP, setup the IP but I can not connect to it.
Code: Select all
#include <ESP8266WiFi.h>
IPAddress myIP;
const char *sid = "Mysid";
const char *pass = "Mypass";
void setup()
{
delay(100);
Serial.begin(9600);
Serial.println("Hello");
WiFi.persistent(false);
WiFi.mode(WIFI_OFF);
WiFi.mode(WIFI_STA);
WiFi.begin(sid, pass);
delay(100);
}
void loop() {
int i, i_prev;
if (WiFi.status() != WL_CONNECTED) {
Serial.print("Connecting to sid: "); Serial.println(sid);
Serial.print("Password: "); Serial.println(pass);
while (WiFi.status() != WL_CONNECTED) {
Serial.print(WiFi.status()); Serial.print("|");
delay(500);
/*
WL_IDLE_STATUS = 0,
WL_NO_SSID_AVAIL = 1,
WL_SCAN_COMPLETED = 2,
WL_CONNECTED = 3,
WL_CONNECT_FAILED = 4,
WL_CONNECTION_LOST = 5,
WL_DISCONNECTED = 6
*/
}
//Print the IP address
myIP = WiFi.localIP();
Serial.print("IP address: "); Serial.println(myIP);
}
i = WiFi.softAPgetStationNum();
if (i_prev != i) Serial.printf("Stations connected=%d\r\n", i);
i_prev = i;
delayMicroseconds(100);
}
I got the output like:
Code: Select all
Hello
Connecting to sid: Mysid
Password: Mypass
