Getting Started

Software Development Environment Preparation

Complete the below steps to develop applications on a Windows or Linux System.

Machine Environment

You can select Azure Sphere development kit for your machine and install software.

  • On Windows 10 (1st anniversary update or more)
    • Visual Studio Enterprise, Professional or Community 2019
    • Visual Studio Code
  • On Linux
    • Visual Studio Code

Azure Sphere SDK Installation

Download Azure Sphere SDK and install it.

Then complete Azure Sphere SDK Extension Install for development tool.

Visual Studio Code settings.json

Please check cmake options in settings.json for Visual Studio Code:

"cmake.cmakePath": "C:\\Program Files\\CMake\\bin\\cmake.exe",
"cmake.configureSettings": {
"CMAKE_MAKE_PROGRAM": "C:\\ninja\\ninja-v1.10.0\\ninja.exe",
"AzureSphere.ArmGnuPath": "C:\\Program Files (x86)\\GNU Arm Embedded Toolchain\\9 >2020-q2-update\\bin",
"AzureSphere.SdkPath": "C:\\Program Files (x86)\\Microsoft Azure Sphere SDK",

Azure Sphere Debugger

The MT3620 exposes two dedicated UARTs and SWD interface for debugging. The Azure Sphere PC software tools require the use of a USB-to-UART interface that exposes these interfaces to a PC in a way that allows the tools to recognize and interact with them. For this, ASG200 components have a ‘Debugger’ board which can attach to 18pin headers on ASG200. To use this debugger board, user should init the interface information with FTDI tools.

Please follow these steps described in this link:

Development Environment

Azure Sphere CLI

The azsphere.exe command-line utility supports commands that manage Azure Sphere elements. For the more details, enter the below link:

On Azure Sphere Developer Command Prompt Preview, the option, -?, helps to show the command information.

Register User Account

To manage Azure Sphere elements for development, log in Azure Sphere Developer Command Prompt Preview with Microsoft account. To use Azure Sphere Security Service, Microsoft Account is required.

Log in on azsphere login command (Needed the option, –-newuser, with azsphere login command to register the account only have to sign in once.)

azsphere login –newuser <MS Account>

Azure Sphere Tenant

An Azure Sphere tenant provides a secure way for your organization to remotely manage its Azure Sphere devices in isolation from other customer’s devices. And it is accessed based on RBAC (Role Based Access Control). Only people with an account in that directory will be able to manage devices within your Azure Sphere tenant.

Role assigned an account in the Azure Sphere tenant

Follow these steps to select the role assigned Azure Sphere tenant:

  1. Search the tenant list
azsphere tenant list
  1. Select the tenant from the list with tenant id
azsphere tenant select -I <tenant id>
  1. Check the selected tenant
azsphere tenant show-selected

Create new tenant

There is no existed Azure Sphere tenant or assigned role in it. User can create new Azure Sphere tenant.

azsphere tenant create -n <tenant name>


Check the selected tenant for development environment. Once ASG200 is claimed to the Azure Sphere tenant, claiming to other tenants is prohibited following Azure Sphere Security policy.

Recovery Interface

Once ASG200 is connected to the internet, Azure Sphere OS updates are initiated automatically via OTA (Over The Air) Wi-Fi interface. Also, user can manually update Azure Sphere OS with recovery. Recovery is the process of replacing the latest system software on the device using a special recovery bootloader instead of cloud update.

Follow these steps to update the latest Azure Sphere OS:

  1. Set Wi-Fi interface
azsphere device wifi add --ssid <SSID> --psk <Password>
  1. Check Wi-Fi status
azsphere device wifi show-status
  1. Recovery for Azure Sphere OS update
azsphere device recover
  1. Check Azure Sphere OS version
azsphere device show-os-version

Development Mode

Connect Debugger board which is attached to ASG200 debug interface to PC and set development mode for debugging on In Azure Sphere Developer Command Prompt Preview.

On development mode, OTA is inactivated.

Development mode for debugging (Add option for RT App debugging).

--enablertcoredebugging option requires administrator privilege because it installs USB driver for the debugger

azsphere device enable-development --enablertcoredebugging

Configuration Wi-Fi Network Settings

Scan for Wi-Fi Access Point

A quick-check of Wi-Fi reception can be done:

azsphere device wifi scan

Configuring the Wi-Fi Network Settings

  1. Set new Wi-Fi
azsphere device wifi add –-ssid <SSID> --psk <Password>

azsphere device wifi add -s <SSID> -p <Password>
  1. Verify the present Wi-Fi connectivity status
azsphere device wifi show-status
