SSL Issue when trying to append values using FreeRTOS.

[roshanyadav29]

I am getting this error when trying to append the values. Can anyone help me?
17:28:11.740 -> > ERROR.mRunUntil: SSL internals timed out!
17:28:11.740 -> > ERROR.mConnectSSL: Failed to initlalize the SSL layer.
17:28:11.740 -> > ERROR.mConnectSSL: Unknown error code.

Is there a way to manually close or restart the connection within the code?

I am using ESP32C3 Board with Arduino IDE v2.3.2. I am trying to implement FreeRTOS-based tasks to connect to Wi-Fi, get the time and data, process it and then send it to Google Sheets. Any Leads to why I am getting this error would be greatly appreciated

If you set the server or root CA certificate, that certificate is expired. You have to provide a new certificate.

If you don't know how, you should not use GSheet.setCert.

The main task for me is only setup() or loop().

[roshanyadav29]

Again I am sorry, wrong choice of words. You are correct, main task is setup() and loop(). I declare all the functions having tasks inside the setup() and my loop() is empty. Now one of the tasks inside setup (again sorry for the previous bad choice of words) has a for(;;) which has a switch case statement.

void thread_process(void* arg) {

  for (;;) {
    switch (state) {
      case process_IDLE:
        break;
      case process_READ_Sensor:

        Serial.printf(FILE_TAG "Read Sensor data, state -> %d\n", state);

.
.
.
.
        process_val.aht_temp.temp = getData_temperature();
        process_val.aht_temp.rh = getData_humidity();

        state = process_AQI_Sensor;  // goto publish sensor data
        break;

      case process_AQI_Sensor:
#if __USE_SERIAL_DEBUG__
        Serial.printf(FILE_TAG "Calculate AQI from Sensor data, state -> %d\n", state);
#endif

// ** some functions **

        state = process_POST_Sensor;
        break;

      case process_POST_Sensor:
#if __USE_SERIAL_DEBUG__
        Serial.printf(FILE_TAG "Publish Sensor data, state -> %d\n", state);
#endif
        if (check_sheets_ready()) {
          append_values_aht(__date__, __time__, process_val.aht_temp.temp, process_val.aht_temp.rh);
        }
        state = process_IDLE;
    }
    vTaskDelay(pdMS_TO_TICKS(10));  //task delay in ms
  }
}

Maybe this snippet might help in visualizing the approach. Again the switch is made using a state variable, that is controlled by a timer. So you are definitely correct on that No Networking Functions in the ISR or Callback. Sorry for the vague explanation earlier.

[roshanyadav29]

This is the timer callback that I was talking about. I forgot to add it in the above text.

/* Define a timer callback function */
void vProcessTimerCallback(TimerHandle_t xTimer) {
  // read everytime the timer is called back (in seconds)
  state = process_READ_Sensor;
}

[roshanyadav29]

I don't know what the problem is but,

  case process_POST_Sensor:
#if __USE_SERIAL_DEBUG__
      Serial.printf(FILE_TAG "Publish Sensor data, state -> %d\n", state);
#endif
      if (check_sheets_ready()) {
        append_values_aht(__date__, __time__, process_val.aht_temp.temp, process_val.aht_temp.rh);
      }
      state = process_IDLE;
  }
  vTaskDelay(pdMS_TO_TICKS(10));  //task delay in ms
}

Instead of this approach, I created a separate task within case process_POST_sensor which would append the value of the sensor and then called vTaskDelete(NULL). Somehow this approach works and I can add all the values to the sheets. Not sure why the previous one wasn't working
