Reboot Reset Reason

[antoniuschan99]

In the esp insights marketing, it says you can have esp insights upload the core dump logs to the cloud if there was a crash upon reboot. Is there an esp insights implementation or should we use esp_reset_reason()? Thanks!

`

include "esp_system.h"

void app_main() { // Check the reason for the last reset esp_reset_reason_t reset_reason = esp_reset_reason();

// Determine the reset reason and take appropriate action
switch(reset_reason) {
    case ESP_RST_UNKNOWN:
        // This is the power-on reset, and the reason is unknown.
        // It could be a fresh boot or due to power-up.
        break;

    case ESP_RST_POWERON:
        // The system was reset due to a power-on event.
        break;

    case ESP_RST_EXT:
        // The system was reset by an external reset signal.
        break;

    case ESP_RST_SW:
        // The system was reset by software using the RESET button.
        break;

    case ESP_RST_PANIC:
        // The system was reset due to a panic (exception/crash).
        // You can take necessary recovery or logging actions here.
        break;

    case ESP_RST_INT_WDT:
        // The system was reset because the internal watchdog timer timed out.
        break;

    case ESP_RST_TASK_WDT:
        // The system was reset because a task watchdog timeout occurred.
        break;

    case ESP_RST_WDT:
        // The system was reset by the hardware watchdog timer.
        break;

    case ESP_RST_DEEPSLEEP:
        // The system was reset from deep sleep mode.
        break;

    default:
        // Other reset reasons, if any, can be handled here.
        break;
}

@antoniuschan99 ESP-Insights already sends the reboot reason. It also optionally sends the coredump on crash. You need to enable IDF's coredump feature to be able to do the same. Please follow this and set core dump to flash if you want to get crash info: https://docs.espressif.com/projects/esp-idf/en/release-v5.1/esp32/api-guides/core_dump.html

Thanks for your reply. I mean upon reboot, is there an implementation/function within esp insights api to know if the reboot was caused by a crash? Yes, I am currently able to get it to send coredump info to esp insights cloud.

@antoniuschan99 as you've suggested in main issue description, esp_reset_reason is the correct way to go. The same API is also used by ESP-Insights internally.
