Samples for the Azure IoT service SDK for Node.js

This folder contains simple samples showing how to use the various features of the Microsoft Azure IoT Hub service from a device running C code.

Registry
- registry_sample.js: Manage the device ID registry of IoT Hub.
- registry_bulk_sample.js: Create a set of device IDs in the device ID registry of IoT Hub in bulk.
- create_device_with_cert.js: Create a new device ID using an X-509 certificate.
Messaging
- send_c2d_message.js : Send C2D messages to a device through IoT Hub.
Device services samples (Device Twins, Methods, and Device Management) (See device management patterns for instructions on running the device management patterns samples):
- twin.js: Interact with the Device Twins from a back-end app.
- twin_query.js: Interact with the Device Twins using queries from a back-end app.
- device_method.js: Invoke a C2D Direct Method on a device through IoT Hub.
- dmpatterns_reboot_service.js: Initiate a C2D method to reboot a device and view progress through the twin reported properties.
- dmpatterns_fwupdate_service.js: Implement the service side of the firmware update DM pattern.
- job_query.js: Use the jobs query feature of the service SDK.
- schedule_job.js: Schedule device management jobs.
Uploading blob to Azure:
- receive_file_notifications.js: Track the progress of the file "upload to blob" by devices.

In order to run the device samples you will first need the following prerequisites:

Node.js v0.10 or above on your target device. (Check out Nodejs.org for more info)
Create an Azure IoT Hub instance

Get the following files from the current folder:

package.json
sample_file.js (where sample_file.js is one of the files listed above and available in this folder)

Place the files in the folder of your choice on the target machine/device then go through the following steps:

Locate the following code in the file:

var connectionString = '[IoT Connection String]';

Replace [IoT Connection String] with the connection string for the access policy you want to use (learn more about access policies here). Save the changes.
From a shell or Node.js command prompt, navigate to the folder where you placed the sample files. Run the sample application using the following commands:
```
npm install
node sample_file.js
```

To run the Device Management samples, follow our DM patterns documentation.
