This is a native module written in C programming language, which can be loaded by the Azure IoT Gateway SDK.

The convertor module will receive the message sent from a BLE or Simulated_Device module, and then convert the data into json format as

{"deviceId": "Intel NUC Gateway", "messageId": 0, "temperature": 0.0}

You can run the SDK's BLE or simulated_device_cloud_upload sample correctly.

clone this repo into a linux system (Intel NUC), then run the following command:

chmod 777 build.sh  # change the build script runnable
sed -i -e "s/\r$\/\/" build.sh  # remove the invalid windows character
./build.sh

Note the libmy_module.so binary file's absolutely path.

1. Choose the ble_gateway.json or simulated_device_cloud_upload.json according to whether you run a BLE sample or simulated_device sample

2. Add a new module as MyModule using the following json

   {
     "name": "MyModule",
     "loader": {
       "name": "native",
       "entrypoint":{
         "module.path": "[Your libmy_module.so path]"
       }
     },
     "args": null
   },

3. Modify the links part

   a. if you are using the BLE sample, modify the links part

   from:

   {
       "source": "SensorTag",
       "sink": "mapping"
   }

   to:

   {
       "source": "SensorTag",
       "sink": "MyModule"
   },
   {
       "source": "MyModule",
       "sink": "mapping"
   }

   b. if you are using the simulated_device_cloud_upload sample, modify the links part

   from:

   {
       "source": "BLE",
       "sink": "mapping"
   }

   to:

   {
       "source": "BLE",
       "sink": "MyModule"
   },
   {
       "source": "MyModule",
       "sink": "mapping"
   }
