ESP32-LWOS

A simple library I made for my esp32 projects where I am only able to use Arduino OTA. This library ensures you don't accidently lock yourself out of OTA and provides simple watchdog capabilities. If its unable to connect to WiFi, it starts its own. If it gets stuck in a reboot loop, it will boot into a safe mode where only OTA is enabled. If it gets stuck in an infinite while loop, it will restart the esp32. Optionaly, if it fails to connect to Wifi, it will start its own AND go into an OTA only mode via "UseWifiFailoverPanic(bool)"

Install instructions: Download LWOS.zip, wnzip the folder and add it to your libraries folder for Arduino IDE located In your sketch folder (Ussually Documents/ArduinoIDE/libraries)

Example Code:

#include <LWOS.h>

LWOS lwos(3, 1000); // this sets number of crashes before booting into OTA only mode to 3, and the watchdog timer to 1000ms

void setup() {
    Serial.begin(115200);
    lwos.UseWifiFailoverPanic(true); // Use if you want it to failover to OTA only mode if it fails to connect to Wifi. This needs to be called before LWOS.begin()
    lwos.begin("SSID", "PASSWORD"); // Set wifi SSID and Password, if it fails to connect to this wifi, it will start its own named "LWOS_OTA". This needs to be at the start of setup() as any code before it is unprotected.
    Serial.println("Hello World!");
}

void loop() {
    lwos.handle(); // Put LWOS.handle() at the start of your main loop
    if (random(0,1000) == 1){ // 1 in 1000 chance to reboot into OTA only mode.
      Serial.println("AHHHH");
      lwos.panic();
      ESP.restart();
    }
    if (random(0,100) == 2){ // 1 in 100 chance to simulate a watchdog timer expiration.
     Serial.println("Simulating Crash"); 
     delay(10000);
    }
    if (random(0,100) == 3){ // 1 in 100 chance to simulate a process taking a long time
      Serial.println("Long processing Time");
      lwos.changeWatchdog(10000); // Changes watchdog timer to a longer time temporarily
      delay(5000);
      lwos.changeWatchdog(1000); // Changes watchdog timer to 1000ms
    }
    if (random(1,400) == 1){ // 1 in 400 chance to restart, a sucsesfull restart will clear the crash count.
      Serial.println("Restarting!");
      lwos.restart(); // Use this instead of ESP.Restart(). ESP.Restart() will count as a crash and will incriment the crash count.
    }
    delay(100);
}
