ESP8266 fails to reconnect to FIREBASE

[ypegua]

When i turn on the ESP8266 everything works fine for a while, until the connection with firebase for some reason stops, and im having problems reconnecting to firebase again. Can somebody give me an idea to solve this? without manually reseting the ESP8266 (witch kills the purpose of the ESP8266)

this is my code:

`#include <ESP8266WiFi.h>
#include<FirebaseArduino.h>

#define FIREBASE_HOST "XXXXXXX.firebaseio.com" //Your Firebase Project URL goes here without "http:" , "" and "/"
#define FIREBASE_AUTH "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX" //Your Firebase Database Secret goes here

#define WIFI_SSID "wifi" //your WiFi SSID for which yout NodeMCU connects
#define WIFI_PASSWORD "XXXXX"//Password of your wifi network

String varCooler;

#define Cooler 14 //D5
int val2;

void setup()
{
Serial.begin(115200); // Select the same baud rate if you want to see the datas on Serial Monitor

pinMode(Cooler,OUTPUT);

digitalWrite(Cooler,HIGH);

WiFi.begin(WIFI_SSID,WIFI_PASSWORD);
Serial.print("connecting");
while (WiFi.status()!=WL_CONNECTED){
Serial.print(".");
delay(500);
}
Serial.println();
Serial.print("connected:");
Serial.println(WiFi.localIP());

Firebase.begin(FIREBASE_HOST,FIREBASE_AUTH);
varCooler = Firebase.getString("Cooler");
Firebase.setString("Cooler","1");
Firebase.setString("Cooler",varCooler);
}

void firebasereconnect()
{
Serial.println("Trying to reconnect");
Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH);
}

void loop()
{

if (Firebase.failed())
{
Serial.print("setting number failed:");
Serial.println(Firebase.error());
firebasereconnect();
return;
}

val2=Firebase.getString("Cooler").toInt(); //Reading the value of the varialble Status from the firebase

if(val2==1) // If, the Status is 1, turn on the Relay2
{
digitalWrite(Cooler,HIGH);
Serial.println("Cooler OFF");
}
else if(val2==0) // If, the Status is 0, turn Off the Relay2
{
digitalWrite(Cooler,LOW);
Serial.println("Cooler ON");
}

}`

Cooler is just variable that is use for output

same issue someone can help us?

[ypegua]

for now im just using the ESP.reset(); when the connection stops. its not ideal but its keeps the ESP8266 working 24/7.

[MrSuhov]

@ypegua, how does your esp knows that the connection was lost? With what line of code?

[ypegua]

You can do this:
if (Firebase.failed())
{
Serial.print("setting number failed:");
Serial.println(Firebase.error());
ESP.reset();
}

[MrSuhov]

Unfortunately, in my case I got empty Firebase.error() in about 10 minutes, however I still can update values to the firebase. So in my case Firebase.error() does not mean the connection was lost. And I don't want to reboot my esp every 10 min.

[ypegua]

Me neither, its just a solution until I find the real problem.

[josacore2017]

yep it work thx for ESP.reset(); solution but it takes time to reset 2 seconds. but it works, if you find the solution please share it , i do the same .

[ypegua]

of course!

I have the same problem, the connections fails at random times.

[JanChodorowski]

@ypegua Firebase.begin() only sets the strings inside of the Firebase object, so effectively does nothing, since the values are the same. It DOES NOT RECONNECT.

void FirebaseArduino::begin(const String& host, const String& auth) { host_ = host.c_str(); auth_ = auth.c_str(); }

What's more when I used that in loop() it caused the streaming to fail, not sure yet why.

[gedeondt]

Same problem here. Anyone found a solution better than resetting?

[hugolimachaves]

I have the same error. Did anyone try to debug the library?

[philipnguyen8588]

I have the same error. Did anyone try to debug the library?

I found the error in the library Firebase.cpp => void FirebaseCall::analyzeError
You should change this code
Before

void FirebaseCall::analyzeError(char* method, int status, const std::string& path_with_auth) {
if (status != 200) {
error_ = FirebaseError(status,
std::string(method) + " " + path_with_auth +
": " + http_->errorToString(status));
}
}

After

void FirebaseCall::analyzeError(char* method, int status, const std::string& path_with_auth) {
if (status != 200) {
error_ = FirebaseError(status,
std::string(method) + " " + path_with_auth +
": " + http_->errorToString(status));
} else {
error_ = FirebaseError();
}
}
