Как повторно синхронизировать время с NTP-сервера в esp-idf?

0 голосов
/ 07 мая 2019

Я использую ESP32 с esp-idf. Мне нужно правильное время, поэтому я пытаюсь повторно синхронизировать время с NTP-сервером. Я использую этот пример. [1]: https://github.com/espressif/esp-idf/tree/master/examples/protocols/sntp

Когда я снова вызываю метод receive_time (), устройство перезагружается.

Что я не так? Я не нашел ничего, что поможет.

Rebooting...

Есть мои методы: 

This give back the timestamp.
void getDateTime(char *dateTime)
{
  char *TAG = "getDateTime";
  time_t now;
  struct tm timeinfo;
  time(&now);
  localtime_r(&now, &timeinfo);
  char strftime_buf[64];
  setenv("TZ", "GTM-2", 1);
  tzset();
  localtime_r(&now, &timeinfo);
  strftime(strftime_buf, sizeof(strftime_buf), "%c", &timeinfo);
  sprintf(dateTime, "20%d-%d-%d+%d:%d:%d", timeinfo.tm_year - 100, timeinfo.tm_mon + 1, timeinfo.tm_mday, timeinfo.tm_hour, timeinfo.tm_min, timeinfo.tm_sec);
}

This method trying to update time. 
void syncTime()
{
  char *TAG = "syncTime";
  obtain_time();

}

static void obtain_time(void)
{
  static const char *TAG = "obtain_time";
  initialize_sntp();
  time_t now = 0;
  struct tm timeinfo = {0};
  int retry = 0;
  const int retry_count = 10;
  while (retry!=retry_count)// timeinfo.tm_year < (2016 - 1900) && ++retry < retry_count )
  {
    ESP_LOGI(TAG, "Waiting for system time to be set... (%d/%d)", retry, retry_count);
    vTaskDelay(2000 / portTICK_PERIOD_MS);
    time(&now);
    localtime_r(&now, &timeinfo);
  }
}
