The problem is due to Firebase server connection was reset when use ping and my library was not detect any change through WiFi core and assumed that the connection to Firebase is still alive and not need to restart server server connection.
To work around this issue at this time, please call ping before call begin stream or avoid to use ping.
This issue will be fixed in the next update soon.
from firebase-esp8266.
This is because device cannot connect to internet even the WiFi was connected.
The error connection refuse is directly return by esp8266 core when connection to server was failed.
Please try the following.
- Reset your router.
- Connect to another WiFi hotspot.
- Connect to soft AP created with your computer.
- Connect to your mobile phone WiFi hotspot.
from firebase-esp8266.
I have already tried connecting with my mobile phone hotspot and also tried connecting with my laptop hotspot. I cross checked and the Internet connection was properly working, actually I have also developed an app for updating values on firebase database and that app is working properly which ensures that Internet connection was proper and working.
Already tried connecting to 3 to 4 different WiFi hotspots, but the problem still retains.
from firebase-esp8266.
Please try this
#include <WiFiClientSecureAxTLS.h>
using namespace axTLS;
WiFiClientSecure client;
#include <ESP8266WiFi.h>
#define FIREBASE_HOST "xxxxxxxxxxxxxxxx.firebaseio.com"
#define FIREBASE_AUTH "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
void setup() {
Serial.begin(115200);
Serial.println();
Serial.print("connecting to WiFi");
WiFi.mode(WIFI_STA);
WiFi.begin("SSID", "PSWxxxxxxxxx");
while (WiFi.status() != WL_CONNECTED)
{
Serial.print(".");
delay(200);
}
Serial.println("");
Serial.println("WiFi connected.");
Serial.println("IP address: ");
Serial.println(WiFi.localIP());
Serial.println();
if (client.connect(FIREBASE_HOST, 443)) {
Serial.println("Connect to Firebase OK");
client.print("GET /number.json?auth=");
client.print(FIREBASE_AUTH);
client.print(" HTTP/1.1\r\n");
client.print("Host: ");
client.print(FIREBASE_HOST);
client.print("\r\n");
client.print("Connection: close\r\n\r\n");
while (client.connected() && !client.available())
delay(1);
if (client.connected() && client.available())
while (client.available())
Serial.print((char)client.read());
} else {
Serial.println("Connect to Firebase failed!");
}
}
void loop() {
}
And post the printed serial.

If problem still existed, please update ESP8266 Arduino Core.
From Arduino IDE, go to Tools > Board: "xxxxx" > Boards Manager.., search for esp8266 and select version 2.5.0 and install.
from firebase-esp8266.
Thank you for the response.
I have already installed the correct version i.e. 2.5.0 of the ESP8266 Arduino Core library.
Here's the printed serial output.
from firebase-esp8266.
Ok now you're ready to connect.
The library should work now.
The problem I guess is the versions of Arduino core that checked in my library are 2.4.0, 2.4.1, 2.4.2 and 2.5.0. If user installs beta or rc version or older version, some files are not included properly due to WiFi client changes since v 2.4.2 and 2.5.0.
This solved in latest commit.
from firebase-esp8266.
Okay, so I have already updated the library and it worked for 2-3 times properly, but again it started to cause the same trouble. Please help to solve this issue ASAP. Here's a screenshot-
from firebase-esp8266.
To ensure Internet connectivity I have also performed ping test.
from firebase-esp8266.
From Arduino IDE go to menu
Tools > Debug port:, choose "Serial"
Tools > Debug Level:, choose "WIFI"
Tools > lwIP Variant:, choose "v2 Lower Memory"
Upload below sketch.
Copy all serial and post it when it shows Connect to Firebase failed!

It's connecting to firebase successfully, the connection only fails when I turn off the mobile data from my smartphone...otherwise everything works just fine.
from firebase-esp8266.
If this works, the library should work too, because this is the way I use in the library.
from firebase-esp8266.
But still it is showing connection refused, and my Internet connection is working properly as you can see in the image. Both the device my laptop and esp8266 are connected to the same WiFi network.
from firebase-esp8266.
Please show your serial debug and your sketch you currently used.
from firebase-esp8266.
Make sure FIREBASE_HOST should not ending with any character after .com and not leading with https://
#define FIREBASE_HOST "???????.firebaseio.com"
#define FIREBASE_AUTH "????????????????"
from firebase-esp8266.
And update Firebase-ESP8266 library to v 1.0.5.
from firebase-esp8266.
FIREBASE_HOST and FIREBASE_AUTH are configured correctly and I have updated the Firebase-ESP8266 library recently.
from firebase-esp8266.
Please paste your code (delete your host and auth).
from firebase-esp8266.
Didi you missed?
if (!Firebase.beginStream(firebaseData, path))
{
Serial.println("------------------------------------");
Serial.println("Can't begin stream connection...");
Serial.println("REASON: " + firebaseData.errorReason());
Serial.println("------------------------------------");
Serial.println();
}

Here's a link to my code-
https://github.com/AMAN-KHATRI/ESP8266/blob/master/Clikofy.ino
from firebase-esp8266.
Okay, now I have removed ping completely from the code but the issue still persists. I really don't have any idea why this is happening, I have already tried restarting the router, connecting with my mobile phone hotspot, also tried connecting from one of my friend's mobile hotspot but yet no visible change.
Please help me to solve this issue. Thankyou.
from firebase-esp8266.
Ok I finally fixed this issue and some bugs in mode switching. The version is still 1.0.5, please update the library and check.

Ok I finally fixed this issue and some bugs in mode switching. The version is still 1.0.5, please update the library and check.
still not working on my end and I just downloaded this library on a brand new arduino IDE installation.
from firebase-esp8266.
@affibox Which ESP8266 Arduino Core version you installed?
Please update ESP8266 Arduino Core to version 2.5.0 (or older 2.4.2).
@affibox and @AMAN-KHATRI
Please delete the current version of Firebase-ESP8266 from library folder.
Download and install the new one of v 1.0.5 (I just fixed the issue and update core and its header few monent ago but not change the version number)
from firebase-esp8266.
Thank you so much. Now the library is working perfectly fine. One more thing, when I update the firebase using setInt or updateNode, it takes about 2 seconds to reflect changes, and at that particular time no other code is functional, everything just stops working. So, is there any faster and more efficient way to do so?
One more thing, can I use ping now in between the code?
from firebase-esp8266.
It depends on size of json data passed to updateNodeSilent, time for WiFi client to start new SSL connection after disconnected from stream because you use the same Firebase Data object.
Another way is use difference Firebase Data object for stream and for normal operations (get/set/push/update/delete) as in examples. But beaware of each Firebase Data Object takes about 18-20k memory.

@mobizt thanks...!!!

Thanks, @mobizt. I'll give it a try.
