Problem Sending MQTT messages using FreeRTOS

[lealoureiro]

Hello,

I have an FreeRTOS task that sends 4 MQTT messages (using LwIP MQTT) every 10 seconds:

void HomeAssistantConfigTask(void *argument)
{
  /* USER CODE BEGIN HomeAssistantConfigTask */
  /* Infinite loop */
  for(;;)
  {
 
    SendAvailabilityMessage();
    SendPowerConfigMessage();
    SendDisplayConfigMessage();
    SendFrontLedConfigMessage();
    osDelay(10000);
 
  }
 
  osThreadTerminate(NULL);
 
  /* USER CODE END HomeAssistantConfigTask */
}

But most of the times the last 2 messages are not sent... Seems like the thread is being interrupted before sending the message. I also tried to add osDelay between sending messages and I have same problem.

I have in total 4 FreeRTOS tasks and this one is configured like this:

osThreadId_t HMConfigTaskHandle;
const osThreadAttr_t HMConfigTask_attributes = {
  .name = "HMConfigTask",
  .stack_size = 4096 * 4,
  .priority = (osPriority_t) osPriorityAboveNormal2,
};

The other tasks are running every 100ms and every 5s.

I'm using STM32F407VGT with FreeRTOS using CMSIS_V2.

Thanks for reading.
