About this document

This document describes how to how to setup Mono and run the Device Client HTTPS Sample application on a Toradex module with Linux. This multi-step process includes:

• Configuring Azure IoT Hub
• Registering your IoT device
• Build and deploy Azure IoT SDK on device

Step 1: Prerequisites

You should have the following items ready before beginning the process:

• Setup your IoT hub
• Provision your device and get its credentials
• Build DeviceClientHttpsSample C# sample application
• Ensure the module is flashed with Toradex V2.5 Linux image or newer.

Step 2: Prepare your Device

1. Insert the module into a compatible carrier board. Power on the system and connect to the internet.

2. Use the command line to install Mono and necessary dependencies:

   opkg update
   opkg install mono mono-dev ca-certificates
   

3. Import trusted root certificates:

   mono /usr/lib/mono/4.5/mozroots.exe --import --sync
   

Step 3: Build and Run the sample

1. Copy the the contents of the compiled Device Client HTTPS Sample application's bin directory to the module.

2. Execute the application with Mono:

   mono DeviceClientHttpsSample.exe
   

3. See Manage IoT Hub to learn how to observe the messages IoT Hub receives from the Device Client HTTPS Sample application and how to send cloud-to-device messages to the Device Client HTTPS Sample application.
