ESP32-SE Lo-Fi内置天线LoRaWAN传输看门狗超时故障排查求助

我有一台ESP32-SE Lo-Fi设备，需要通过内置天线利用LoRaWAN协议将数据上传至第三方数据库。目前采用MCCI Arduino LoRaWAN Library编写了代码（已隐去AppEUI、DevEUI、APPKEY等敏感信息），但设备运行时频繁触发Core 1中断看门狗超时的Guru Meditation Error，无法正常完成数据上传流程。

代码片段 #

// 隐去AppEUI、DevEUI、APPKEY
#include <Arduino.h>
#include <lmic.h>
#include <hal/hal.h>
#include <SPI.h>

// 敏感信息已移除
const u1_t PROGMEM APPEUI[8] = { /* 已隐去 */ };
const u1_t PROGMEM DEVEUI[8] = { /* 已隐去 */ };
const u1_t PROGMEM APPKEY[16] = { /* 已隐去 */ };

void os_getArtEui(u1_t* buf) { memcpy_P(buf, APPEUI, 8); }
void os_getDevEui(u1_t* buf) { memcpy_P(buf, DEVEUI, 8); }
void os_getDevKey(u1_t* buf) { memcpy_P(buf, APPKEY, 16); }

static osjob_t sendjob;

// 发送回调
void onEvent(ev_t ev) {
    switch(ev) {
        case EV_SCAN_TIMEOUT:
            Serial.println("EV_SCAN_TIMEOUT");
            break;
        case EV_BEACON_FOUND:
            Serial.println("EV_BEACON_FOUND");
            break;
        case EV_BEACON_MISSED:
            Serial.println("EV_BEACON_MISSED");
            break;
        case EV_BEACON_TRACKED:
            Serial.println("EV_BEACON_TRACKED");
            break;

            Serial.println("EV_JOINING");
            break;
        case EV_JOINED:
            Serial.println("EV_JOINED");
            // 加入成功后调度发送任务
            os_setCallback(&sendjob, sendData);
            break;
        case EV_JOIN_FAILED:
            Serial.println("EV_JOIN_FAILED");
            break;
        case EV_REJOIN_FAILED:
            Serial.println("EV_REJOIN_FAILED");
            break;
        case EV_TXCOMPLETE:
            Serial.println("EV_TXCOMPLETE");
            // 再次调度发送任务
            os_setCallback(&sendjob, sendData);
            break;
        case EV_LOST_TSYNC:
            Serial.println("EV_LOST_TSYNC");
            break;
        case EV_RESET:
            Serial.println("EV_RESET");
            break;
        case EV_RXCOMPLETE:
            Serial.println("EV_RXCOMPLETE");
            break;

            Serial.println("EV_LINK_DEAD");

            Serial.println("EV_LINK_ALIVE");
            break;
        default:
            Serial.print("Unknown event: ");
            Serial.println((unsigned int)ev);
            break;
    }
