Please post your sketch here that I will try and investigate the problem.

[mobizt]

Ok let me investigate.

[UltimatPronin]

I determinate, if I copy all my sketch parts from many tabs in Arduino IDE to 1 big sketch tab - all working VERY GOOD. But If I split my sketck by many tabs - then I get ERRORS. Any Ideas? It is IDE BUG?

[mobizt]

Look like something is calling external function inside while loop and that function hold something in stack which make the stack growth until it crashes with heap (corrupted the heap).

This issue is due to design of your program.

[UltimatPronin]

OK, I will try redesign it. Thank you!

[UltimatPronin]

I find an issue.

Please see on it. There are sketch example:

#include "FirebaseESP8266.h"
#include <ESP8266WiFi.h>

#define FIREBASE_HOST "XXX.firebaseio.com"
#define FIREBASE_AUTH "XXX"
#define WIFI_SSID "XXX"
#define WIFI_PASSWORD "XXX"

//Define FirebaseESP8266 data object
FirebaseData firebaseData;

unsigned long sendDataPrevMillis = 0;

String path = "/Devices";

uint16_t count = 0;

void setup()
{

Serial.begin(115200);

WiFi.begin(WIFI_SSID, WIFI_PASSWORD);
Serial.print("Connecting to Wi-Fi");
while (WiFi.status() != WL_CONNECTED)
{
Serial.print(".");
delay(300);
}
Serial.println();
Serial.print("Connected with IP: ");
Serial.println(WiFi.localIP());
Serial.println();

Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH);
Firebase.reconnectWiFi(true);

if (!Firebase.beginStream(firebaseData, path))
{
Serial.println("------------------------------------");
Serial.println("Can't begin stream connection...");
Serial.println("REASON: " + firebaseData.errorReason());
Serial.println("------------------------------------");
Serial.println();
}
}

void loop()
{
if (!Firebase.readStream(firebaseData))
{
Serial.println("------------------------------------");
Serial.println("Can't read stream data...");
Serial.println("REASON: " + firebaseData.errorReason());
Serial.println("------------------------------------");
Serial.println();
}

if (firebaseData.streamTimeout())
{
Serial.println("Stream timeout, resume streaming...");
Serial.println();
}

if (firebaseData.streamAvailable())
{
Serial.println("------------------------------------");
Serial.println("Stream Data available...");
Serial.println("STREAM PATH: " + firebaseData.streamPath());
Serial.println("EVENT PATH: " + firebaseData.dataPath());
Serial.println("DATA TYPE: " + firebaseData.dataType());
Serial.println("EVENT TYPE: " + firebaseData.eventType());
Serial.print("VALUE: ");
if (firebaseData.dataType() == "int")
Serial.println(firebaseData.intData());
else if (firebaseData.dataType() == "float")
Serial.println(firebaseData.floatData());
else if (firebaseData.dataType() == "boolean")
Serial.println(firebaseData.boolData() == 1 ? "true" : "false");
else if (firebaseData.dataType() == "string")
Serial.println(firebaseData.stringData());
else if (firebaseData.dataType() == "json")
Serial.println(firebaseData.jsonData());
Serial.println("------------------------------------");
Serial.println();
}
}

Please run it and wait for error. In my case it is HTTPC_ERROR_NOT_CONNECTED
When I get it, then STACK Error reboot my nodemcu. It hapenn only on 2.5.1., on 2.5.0 all OK.

Error is on
void FirebaseESP8266::errorToString(int httpCode, std::string &buff)

case HTTPC_ERROR_NOT_CONNECTED:
p_memCopy(buff, ESP8266_FIREBASE_STR_42);
return;

IF I change it (for test) to
case HTTPC_ERROR_NOT_CONNECTED:
//p_memCopy(buff, ESP8266_FIREBASE_STR_42);
p_memCopy(buff, ESP8266_FIREBASE_STR_39);
return;

THERE ARE NO MORE TROUBLES AND STACH ERRORs for me.

[mobizt]

That's not cause or avoid error and not related to stack error because it gives the same result. I also test your posted sketch long enough on esp core 2.5.1 but there's nothing error.

If you still get error from something like this, it may depend on your hardware and wifi situation.

Thank you, for invitations.
