Azure IoT Edge Tiny Hacks

Goal

The connection from the IoT device to Microsoft Azure IoT Hub was troublesome, it needs to support secure protocols such as MQTT. Even if there are Device SDK and IoT Edge as libraries for connecting IoT Hub, but samples that can be used immediately by multiple arbitrary devices are not prepared.

"iot-edge-hacks" provided here aims to send the sensor value obtained by the gateway device in secure to IoT Hub anyway. It can be used as a prototype that transfers the data of the IoT device to the IoT Hub for confirmation, and can be directly used for sending sensor data.

Architecture and Hitnts

We modified the simulated device-to-cloud sample of Azure IoT Edge V1 and send real data to IoT Hub. It uses plane text files because it uses numerically-entered files for delivery, and JSON file setting of file name. It is provided as a difference (patch) file of Simulated device-to-cloud sample.

Precondition

In the operation target environment, it is an important precondition that Azure IoT Edge V1 can already be built and working properly. It works on Ubuntu 18.04 and Raspbian 9.

How to Use

• Building and checking operation of Simulated device-to-cloud sample

  Build a simulated device-to-cloud sample according to the procedure of README and confirm that simulation temperature values...etc. are transmitted by Device Explorer.

• File replacement and build

  Rebuild after overwrite the following files.

  • iot-edge/modules/simulated_device/src/simulated_device.c
  • iot-edge/samples/simulated_device_cloud_upload/src/main.c
  • iot-edge/samples/simulated_device_cloud_upload/src/dpride.h
  • iot-edge/samples/simulated_device_cloud_upload/src/typedefs.h
  • iot-edge/samples/simulated_device_cloud_upload/src/EoControl.c
  • iot-edge/samples/simulated_device_cloud_upload/src/module_service_config_enabled.c
  • iot-edge/samples/simulated_device_cloud_upload/src/module_service_config_disabled.c
  • iot-edge/samples/simulated_device_cloud_upload/src/sim.json

• File settings

  Like "Simulated device-to-cloud sample", after setting "IoTHubName", "IoTHubSuffix", "deviceId", "deviceKey", describe "filename" of the corresponding device.

• Startup

  Start with json file specified by the same procedure as Simulated device-to-cloud sample.

• Test

  While monitoring with Device Explorer etc., verify the operation by modifying the numerical value in the file with the editor.
