Stack smashing protect failure!

[tezmo]

Hej! Great project! I'm loving the addition of video, (but right now do not have a PIR attached, not sure if that is needed)?

My issue is: Stack smashing protect failure!

Any idea how to solve? Didn't adjust any of the code at all. Using an AI thinker ESP32 board, runs the normal Telegram Photo bot fine.

hmmm ... after the wifi setup ...

String stat = "Reboot\nDevice: " + devstr + "\nVer: " + String(vernum) + "\nRssi: " + String(WiFi.RSSI()) + "\nip: " +  WiFi.localIP().toString() + "\n/start";
bot.sendMessage(chat_id, stat, "");

Might be a string issue in the that "stat" line - are all those variables set?

Then the bot.sendMessage which launches wificlientsecrure (which needs bags of memory).

You could throw in this line in a few places to see where you are running out of memory.

Serial.printf("Internal Total heap %d, internal Free Heap %d\n", ESP.getHeapSize(), ESP.getFreeHeap());

Are you using Arduino 1.8.13 and esp32-arduino 1.06???

That "Stack smashing " message is not familiar to me -- running out of heap is familiar, but not that message.

Thanks for the quick response! Might be a string issue in the that "stat" line - are all those variables set? Yes, all are set fine, also ruled out hardware failure now, by testing it on a 2nd board (same results).

Are you using Arduino 1.8.13 and esp32-arduino 1.06??? Yes to both

And i put in a bunch of those.. and i don't get it.. :/

Serial.printf("1 Internal Total heap %d, internal Free Heap %d\n", ESP.getHeapSize(), ESP.getFreeHeap());
  avi_buf_size = 3000 * 1024; // = 3000 kb = 60 * 50 * 1024;
  idx_buf_size = 200 * 10 + 20;
  psram_avi_buf = (uint8_t*)ps_malloc(avi_buf_size);
  if (psram_avi_buf == 0) Serial.printf("psram_avi allocation failed\n");
  psram_idx_buf = (uint8_t*)ps_malloc(idx_buf_size); // save file in psram
  Serial.printf("2 Internal Total heap %d, internal Free Heap %d\n", ESP.getHeapSize(), ESP.getFreeHeap());
  if (psram_idx_buf == 0) Serial.printf("psram_idx allocation failed\n");
  if (!setupCamera()) {
    Serial.println("Camera Setup Failed!");
    while (true) {
      delay(100);
      Serial.printf("4 Internal Total heap %d, internal Free Heap %d\n", ESP.getHeapSize(), ESP.getFreeHeap());
    }
    Serial.printf("5 Internal Total heap %d, internal Free Heap %d\n", ESP.getHeapSize(), ESP.getFreeHeap());
  }
  Serial.printf("6 Internal Total heap %d, internal Free Heap %d\n", ESP.getHeapSize(), ESP.getFreeHeap());
  bool wifi_status = init_wifi();
  Serial.printf("7 Internal Total heap %d, internal Free Heap %d\n", ESP.getHeapSize(), ESP.getFreeHeap());
  // Make the bot wait for a new message for up to 60seconds
  //bot.longPoll = 60;
  bot.longPoll = 5;

  client.setInsecure();
  Serial.printf("8 Internal Total heap %d, internal Free Heap %d\n", ESP.getHeapSize(), ESP.getFreeHeap());
  setupinterrupts();

with the output (the 3 one is on the last line if "init_wifi" after the serial print of the localIP).

What is your timezone? Is it longer than 40 chars?

I use this:

String TIMEZONE = "MST7MDT,M3.2.0/2:00:00,M11.1.0/2:00:00" ; //"GMT0BST,M3.5.0/01,M10.5.0/02";

Maybe my GMT timezone example string is wrong. Try something simple like "GMT". Might be something strange returning from the configtime call - which would be asynchronous to the flow of code ???

My timezone is 38 long, and char array is defined as 40 ???

It prints the ip, but doesn't make it back from the init_wifi()?

[jameszah]

Or take all the time stuff out as an experiment.

[tezmo]

You found it! I increased the tzchar size to 50 and it started working :) My timezone is in the EU en it's MUCH longer. Thanks for the support!

Great stuff, thanks so much for building this!
