HIRING: Senior PM Evangelist - Internet of Things (IoT) - Microsoft, Redmond, WA

I joined the Developer Experience team not too long ago and am focused on helping partners develop IoT products on the Azure IoT stack. I just found out that a sister team is looking for a Senior PM Evangelist to help develop the official IoT related programs we run.  Full details below. 

If interested, send me your resume here: – it’s not a bad idea to include a blurb about yourself and why this role is a fit.



Senior Program Manager Evangelist

As a company, Microsoft is looking to realize 3 bold ambitions: to create more personal computing, to reinvent productivity and business processes with better collaboration and new workflows, and to build an intelligent cloud that can accommodate rich data. Internet of Things (IoT) is a key enabler of these ambitions and a significant growth opportunity for Microsoft.

The Platform Evangelism and Planning (PEP) team within the Developer Experience and Evangelism (DX) Team responsible for defining DX strategic plans from programs and offers through to metrics and field execution to advance the Independent Software Vendor (ISV) and Evangelism agenda for Microsoft technologies.

In the role you will be responsible for:

  • Setting the strategic direction and overall program/project definitions across ISV and Evangelism
  • Defining strategic App Acquisition, Go To Market (GTM - incl. “sell with” opportunity) and Early Adopter Evangelism programs that compel developers and ISV to bet on Microsoft; then enable them to accelerate their success in IoT scenarios.
  • Target setting and prioritization (focus on "why" and "what") for the different sub-projects
  • Representing the voice of the customer, partner and developer in the process

How to Run the Azure IoT Field Gateway on a Raspberry Pi 3

The Azure IoT Field Gateway SDK is a set of libraries that allow you to build a device that acts as a proxy between an individual IoT device and Azure IoT Hub.

Individual IoT devices will connect to the Gateway via some transport layer (BLE, NFC, etc) and the Gateway will forward the device data to IoT Hub. The Gateway will usually aggregate many messages into a single message or convert it to a data protocol (MQTT, AMQP, etc) that IoT Hub understands.

Here’s how to get it the Field Gateway running on a Raspberry Pi 3.

Download Raspbian

I’m using Raspbian Jessie full desktop image.

Get a MicroSD Card and MicroSD USB Card Reader

I have a Kingston 32GB Class 10 MicroSD card and a Transcend USB 3.0 Card Reader

Install Win32DiskImager

This will be used to write Raspbian to the MicroSD card

Copy Raspbian to MicroSD card

Open Win32DiskImager. Find the yyyy-mm-dd-raspbian-jessie.img file. Select your USB drive. Click Write. This took about 5 minutes on my machine.


Get Raspberry Pi Ready

Plug in HDMI monitor, keyboard, mouse and Ethernet cable (you can also use Wifi instead)

Configure Remote Access to Pi

TightVNC allows you to remote desktop into the Raspberry Pi from your Windows desktop.  This step is optional. You could also just use the monitor, mouse and keyboard that is connected to the Pi, but that gets old quick.  There are other options here, but I’ve found TightVNC to be the most reliable when you just need to connect to the Pi from the same wireless network.  If the Pi is on a difference network, then use Weaved.

All your remote options are located here: Feel free to use one that best suits your needs.  SSH with Putty is a good option if you don’t need to access the desktop.

Go to Azure IoT Field Gateway SDK GitHub Page

If you are using TightVNC, on the Pi, open the web browser and go to – that will redirect you to this page on your Pi, so you can easily copy and paste the following commands.

If you are using SSH, then just execute the commands below in your SSH window.

Install Packages

sudo apt-get update

sudo apt-get install curl build-essential libcurl4-openssl-dev git cmake libssl-dev uuid-dev valgrind libglib2.0-dev

Clone the Azure IoT Field Gateway Repo

You can clone into any directly you want. I usually put everything in a /code folder.

git clone --recursive

Checkout the Develop Branch

This is the branch that contains a fix that allows the Gateway to be built on the Pi

git checkout develop

Init Submodules

I like to execute this command after I checkout a branch to be sure I have the latest submodule bits that correspond to my current branch.

git submodule update --init --recursive


Change to the /tools directory and excute ./

cd tools

This will take a while. Come back in 30 mins or so.

Test Failures

You will likely see these test failures, which are known issues reported here on GitHub.  The e2e tests fail because we didn’t setup the IoT Hub connection.  That’ll be the topic of a different blog post.

The following tests FAILED:
          27 - constbuffer_unittests (Failed)
          34 - httpapiex_unittests (Failed)
          41 - sastoken_unittests (Failed)
          63 - mqtt_client_unittests (Failed)
          77 - iothubclient_http_e2etests (Failed)
          79 - iothubclient_mqtt_e2etests (Failed)
          81 - iothubclient_amqp_e2etests (Failed)
         109 - gw_e2etests (Failed)
Errors while running CTest

Copy JSON Settings File to Build Folder

From the root of the repo run this command to copy the sample JSON settings file to the build output folder.

cp ./samples/hello_world/src/hello_world_lin.json ./build/samples/hello_world/hello_world_lin.json

Run Hello_World_Sample

Change to the /build folder

Run the following command to start the sample.

./samples/hello_world/hello_world_sample ./samples/hello_world/hello_world_lin.json

You should now see this output.


This sample writes an entry to the /build/log.txt file. If you open that file you will see the entries. From the /build folder just enter “vi log.txt” to view the file.


You now have the Azure IoT Gateway Running on a Raspberry Pi 3!

Error When Stopped

You might see this error when you stop the gateway – it appears that you can ignore it because it is still writing data to the log file.  I have reported the issue on GitHub.

Error: Time:Fri Aug  5 19:41:42 2016 File:/home/pi/code/azure-iot-gateway-sdk/deps/azure-c-shared-utility/src/consolelogger.c Func:consolelogger_log Line:31 byte array is not a gateway message serialization



Solution to: Microsoft Lync 2013 not found. Go here to download and install:

If you get the following error when trying to install the Lync 2013 SDK….

Microsoft Lync 2013 not found. Go here to download and install: (2)

Do not go to that fwlink.

You need to unzip the lyncsdk.exe and manually install the MSI. I used 7-zip, but you can use whatever zip tool you prefer.


I’m on a x64 machine so I used that one and it installed.
