ESP8266 can not reconnect to firebase

[Newsoul693]

I connected to Firebase successfully, can read data from firebase when data changed normaly. But when I decide to unplug the network cable (in this case, wifi.status() still connecting to wifi but can not access the internet) then plug it again , I can not read data changed anymore, It can not enter the condition Firebase.available() and can not enter the condition Firebase.failed() too. Can somebody give me an idea to solve this? Without manually reseting the ESP8266. I know this issue is related to #388 but I can't sovle this problem. Thanks!
Here is my short code:
Firebase.begin(address.c_str(), auth.c_str()); Firebase.stream("/Led"); } void loop() { if (Firebase.available() == true) { FirebaseObject event = Firebase.readEvent(); String path = event.getString("path"); String data = event.getString("data"); Serial.println(path); Serial.println(data); } if (Firebase.failed()) { Serial.println("streaming error"); Serial.println(Firebase.error()); }

You can try setting or getting any variable on firebase then start the stream again.

Hi maherahmed, thank for your reply! Can you more explain for me? Can you show me an example? I don't know how to getting or setting variable again because my code can't enter if condition anymore and how to start stream again when firebase.stream have to put in void setup()?

Have same issue
#388

Your solution didn't work for me.

@Newsoul693 did you find a solution? I still have the same issue.

@beaconIOT my solution is: I put initial funtion of firebase in setup funtion to loop() and make a bool just run one time. In this funtion just run one time, you need to write: if (client.connect(server, 80)) {
//server maybe www.google.com
//firebase.begin here
//bool exit one time function to funtion while
}
Else
{
Bool false to just loop in one time function
}
Then you write function while (bool one time from above) with fuction of your firebase, and write the function check client connect to host again, if not connect, make this bool true and return the one time funtion.
I cant share my code, but I have tested this for 2 weeks.

@Newsoul693 Thanks for that. It sounds like you had more of an issue with the network (wifi) disconnecting, because your if loop is checking to see if it can reach google's server. I definitely still have internet connection, but it's Firebase that's disconnecting.

I tried the following two techniques, but neither worked for me.

ATTEMPT 1
//In setup(), I call Firebase.begin(FIREBASE_HOST,FIREBASE_AUTH); and I also set a bool called firebaseConnectOnce == true; This indicates that a firebase connection has been made during bootup.

//Then I try triggering the firebase.begin again if the connection is lost
if ((Firebase.success() == false) && (firebaseConnectOnce == true)) {
Firebase.begin(FIREBASE_HOST,FIREBASE_AUTH);
Firebase.stream("/growsettings");
firebaseConnectOnce = false;
}

ATTEMPT 2
//(Same as attempt 1) In setup(), I call Firebase.begin(FIREBASE_HOST,FIREBASE_AUTH); and I also set a bool called firebaseConnectOnce == true; This indicates that a firebase connection has been made during bootup.

if ((Firebase.success() == false) && (firebaseConnectOnce == true)) {
ESP.reset() // This isn't working to reset the ESP8266 for some reason. I think it's because I have a DHT11 sensor using my D0 pin.
}

@beaconIOT my solution just fix for my issue (when wifi still connect but no internet access), with your issue, i think you need to check that esp8266 disconnect or crash by upload data too much. I got data continous then my esp8266 crash, so I use firebase.stream. If you detect that your esp crash, you need to use watch dog.

[beaconIOT]

It's definitely a disconnect issue. I'm also using firebase.stream. I have an OLED screen that indicates the rest of my program is functioning, but it loses connection to Firebase and won't reconnect until I power cycle the unit.

Can you post your code?
