Ex1. ⑤ SENSOR DATA PUBLISH

( 태그 : AWS_IoT_FreeRTOS, AWS_IoT )

1. Enable Sensor Function

• STM32 MCU 보드에 내장된 Sensor 데이터를 수집하여 MQTT 메시지로 Publish 하는 기능을 활성화 시킵니다.

• Sensor Data Read Function

  • Drivers/BSP/B-L475E-IOT01
  • Drivers/BSP/Components/vl5310x

• Sensor Data Collector

  • Applications/Cloud/aws_demos/Src/
  • st_sensordata_collector.c, st_statusled_update.c

• Sensor Data Publish

  • Applications/UCloud/aws_demos/Src/
  • aws_customdemo_runner.c, aws_customerdemo_publish.c, aws_customdemo_main.c

• Custom Demo Enable

  • Sensor Data를 Publish 하는 기능을 활성화 합니다.
  • Applications/Cloud/aws_demos/Inc/main.h
  • CONFIG_ST_CUSTOM_DEMO_ENABLED를 define 합니다.

2. Project Build & Programming

• B-L4S5I-IOT01_aws_demos 프로젝트를 재 build한 후 생성된 binary image를 STM32 MCU 보드에 programming 합니다.
• Terminal 로그에서 Sensor Data를 MQTT로 Publish 하는 것을 확인할 수 있습니다.

3. Check MQTT Message

• AWS IoT 콘솔에서 MQTT message 수신을 확인합니다.
  • Test 메뉴를 선택한 후 MQTT client의 subscriptions을 구성합니다.
  • Topic을 입력합니다. : dt/stm32l475e/sensor-data/topic
  • Subscribe to topic 버튼을 클릭합니다.

• Sensor data가 수신되는 것을 확인할 수 있습니다.
