Internet of Things, A Reference Architecture

by Bob Familiar

We at BlueMetal have a great deal of experience in creating solutions that leveraged connected devices streaming millions of records to cloud hosted repositories, leveraging historical and predictive analytics engines to provide insight and creating immersive experiences that give our clients agility and speed in their daily business activities. Case in point…EnerNOC.


Using Lean Engineering a small team from BlueMetal was able to provide EnerNOC with an amazing user experience in 10 weeks. The application spans twenty four 55” high definition displays combining data streaming from over 35,000 devices around the globe connected to the energy grid with geo-political, social media, environmental and financial data creating a visually stunning global view of EnerNOC’s business domain that is visible to all employees and every visitor to their downtown Boston office.


While this solution was clearly focused on the energy sector, the effort produced a reference architecture for Internet of Things solutions that spans verticals. To prove out the viability of this reference architecture in other verticals, BlueMetal created a Pharmaceutical Trial Scenario and implemented a live reference implementation.

Team Wrap-Up from the 2014 Xamarin Evolve Conference in Atlanta

by Sadie Van Buren

Last week a group of BlueMetal’s software architects and engineers attended Xamarin’s Evolve conference in Atlanta,  and we wanted to share their key takeaways from this exciting conference.

Stelios Avramidis  Stel Avramidis:

Xamarin Evolve was a lot of fun.  Besides all of the great updates from Xamarin I had a chance to experience great sessions from some leading experts in UX mobility and design.  I had a chance to meet and socialize with fellow Bluemetalers from other offices as well as with Matt Larson, our partner manager from Xamarin.

My takeaways are not much of a surprise given the following major announcements:

• The new cross-platform Xamarin Profiler to profile applications on Xamarin.iOS and Xamarin.Android.  This is a huge improvement from their previous mono log profiler.  The new profiler looks and behaves more like Apple’s instruments profiling tool.  Although you could profile a Xamarin.IOS application using native tools such as Instruments it did not provide a consistent cross-platform unified experience for both Xamarin.IOS and Xamarin.Android.

• Another major announcement was the Xamarin Android Player.  This is a godsend for anyone who has done Android development.  The Android emulator provided by Google takes eons to bootstrap and load an application for a debug session.  The new player from Xamarin cuts that time significantly from minutes to seconds.  Anyone doing native Android development should feel jealous and should be sending complaint letters to Google to do the same with their native Android emulator.  Just proves that Xamarin is a great company building great tools and a smart company who knows that keeping developers productive and happy is integral to their success.

• Conversely, Sketches was announced.  Another great tool along the theme of keeping developer productivity and happiness high.  Sketches allows developers to improve on the typical write, build, test, and deploy workflow.  It allows developers to write code and instantly see the intermediate results without building and deploying their code.  This is not limited to just a watch-list output seen in a standard debug session, but what the UI may look like as well.  In sum, Sketches is a cross platform tool that allows developers to quickly prototype and iterate ideas when creating both Xamarin.IOS and Xamarin.Android applications.

• The other major announcement was related to improvements made to the Xamarin Test Cloud.  The Xamarin Test Cloud is an invaluable tool to any organization taking on a native cross platform project especially when it comes to testing Android devices.  Based on this article there are over 19,000 distinct Android devices in the world (  The major takeaways was a new cross platform automated UI testing framework called Xamarin.UITest.  Also, test execution enhancements that allow for parallel execution of test scripts across devices in order to improve overall testing performance in the Test Cloud.  Before this feature submitting test scripts against the test cloud could create a queue of requests that ran one after another on the same device.   Finally, there was a new video playback capture of the application UI while its running though test scripts.

Some other notable announcements was Xamarin support for AWS mobile services, and support of XIB files for their Xamarin.IOS.  However, it was not disclosed when they are going to release the new designer features.  When they do roll out XIB file support developers will no longer need to use XCode’s Interface Builder to create views.

Travis Nielsen  Travis Nielsen:

I would say Xamarin is “evolving” to support the fuller spectrum of mobile development. We now have Sketches for quick prototyping, upgraded platform tools for building (resource monitor and Android virtual machine), a pretty sweet looking testing platform (Xamarin Test Cloud), and Xamarin Insights, a real time monitoring tool that gives you pretty rich user behavior reporting, error logging, and user notifications (“we fixed that bug you were complaining about”).

So Xamarin is becoming more involved in the project plan as you move from left to right…which is smart and necessary. Test Cloud in particular is a potentially killer feature. The company is committed to getting developers tools to make mobile as awesome as possible.

In general, the Xamarin team seems to be growing at a pretty amazing pace. They were very engaged with conference participants and they’re easy to talk to (and work with).

Roman Yugov  Roman Yugov:

XAML/MVVM XAML support was very basic in Xamarin Forms – it supported only object creation and initialization.  C# equivalent (using object Initializers) is equally concise and seems to be very popular. There is not yet a visual designer for XAML. In fact, Charles Petzold mentioned that the preview of his “Creating Mobile Apps with Xamarin.Forms” book did not contain any XAML code at all. Anyway it was still possible to create MVVM based application (and really cool ones as Charles presented in his “Xamarin.Forms is Cooler than You Think” session). Here is a game changer: Technical preview of the Xamarin Forms 1.3.0 release was announced on October 8. It has behaviors, triggers, styles, dynamic resources, styles based on dynamic resources. MVVM Light V5 with full Xamarin support was released by Laurent Bugnion on October 8. Xamarin Forms 1.3.0 with MVVM Light framework could be very attractive to WPF/SL/WinRT developers. It allows almost seamless transition into mobile development.

Custom renderers Another hot topic – may be the hottest, session room was packed. Custom renderer allows to implement platform-specific customization (look and behavior) of Xamarin Forms controls. This technique is especially important for custom control vendors. Major vendors already have native UI controls sets for Xamarin Forms.

Mobile backend as a service (MBaaS) There were two MBaaS providers which presented at the conference: KidoZen and AnyPresence (along with Microsoft and Amazon).


BlueMetal was a proud sponsor of this conference.

The secret to delivery – location, location, location

by James Horgan

Recently, BlueMetal was selected as a finalist for a best UX – product award at MITX, an esteemed network of technology marketers. This was for a large scale data visualization wallboard produced for the energy monitoring company EnerNOC.

What’s really impressive about this experience is we went from this:

Screen Shot 2014-04-30 at 11.26.28 AM

to this:


in under 8 weeks.  Most of our clients and colleagues are astounded by this result and have many questions:

  • Which process did we use: Agile or Waterfall?
  • How many iterations?
  • When did the data architect come on board?

The answer is very simple – we put the team (a UX lead, a data architect, a UI engineer, an animator and a visual designer) all in one room, on site where the wallboard was being installed.

We used parallel streams of work to ensure design was aligned with architecture and that communication between the team was constant and consistent. Due to proximity with the client, the team was able to rapidly problem-solve on the fly. This became crucial as visual design and data got closer together.

There was a classic waterfall process but compressed: Discover, Define and Design, or as we call it: BlueSky, BluePrint and BlueMetal.

During BlueSky, interviews allowed the designer to sketch out the experience quickly, and the developers were part of that brainstorming. This allowed both the UI engineer and data architect to understand the scope of requirements, course-correcting as the design became more established.

With BluePrint we whiteboarded every piece of data that needed to be displayed on the wallboard in a single brainstorming session. Both the client and project team were part of this and a firm agreement was put in place that the brainstorming could not be considered complete until we were all in agreement on every piece of functionality. Drawing this line in the sand created intense focus and a rapid approach to design.

Finally during the BlueMetal stage (Design and Build) we ran separate streams of visual design, UI framework and data architecture, working side by side to not only converge on a rapid prototype but to iteratively create a solid high quality final deliverable.

The key to success on intense projects like this involves rapidly solving problems together, and a lot has to do with location.  By ensuring everyone was sitting side by side, every team member got equal accountability on the success or failure of the project, driving the team forward to ensure a favorable result.

An example is shown below of how location affects team dynamics.


Though both team members are looking at the same screen, they are looking for different things. The visual designer on the left is looking at the readability of the typeface, the colors presented and the meaningfulness of what’s being shown. At the same time, the data architect is looking to see how the live data is feeding into interface and can not only troubleshoot, but work with the designer if the type size doesn’t work with the amount of characters the data is expected to pull in. Similarly, on the live file that both developers and designers worked on in WPF (Windows Presentation Format), designers used styleguide marking to indicate to the UI engineer how to adhere to the style, but also allowed the engineer to communicate in the same design language if certain parameters were not working.


Another simple example is the need for world clocks (shown below), something we observed was needed in the 24/7 work environment of EnerNOC. By having a cohesive team, the creation, placement, styling and implementation of the clocks was something we could easily do within a very short time span.


This type of constant communication, rapid problem solving and parallel streams of work can only happen when your team is in the same room, and you should always decide on WHERE your team delivers before you decide on HOW.

IoT with Azure Service Bus, Netduino and Gimbal

by Amol Ajgaonkar

Netduino is an open source electronics platform using the .NET Micro framework. I was using Netduino to create an IoT application which allows me to turn on the lights in the garage as I come closer to the garage.


  1. Gimbal (Proximity Sensor)
  2. Netduino Plus 2
  3. VeraLite (Z-wave controller)
  4. Z-wave enabled outlet.


  1. Azure Service Bus Queue – Setup to hold the commands/messages sent from the mobile App, consumed by Netduino/WCF service.
  2. Xamarin – To build the mobile app to detect the proximity sensor and send commands to the Netduino using the Azure Service Bus Queue.

This is the way I envisioned it to work:


  1. The proximity sensor will be in the garage.
  2. The mobile app will get the proximity information from the sensor as the phone approaches the garage.
  3. If the user is close, the App will send a message to the Azure Service Bus queue.
  4. Netduino will poll to the queue for new messages.
  5. If Netduino finds a message, the command passed in the message is checked.
  6. The Netduino then connects to Veralite (Z-wave controller) and sends a command to turn the light on/off based on the command in the message queue.

In theory this all should work and it does in most part. I ran into a couple of issues here which I thought might be useful to anyone working on such projects.

  1. Proximity values from any sensor are always fluctuating. They are never precise. It only provides information that sensor is nearby. Don’t rely on the distance value. It is based on the strength of the signal and not reliable.
  2. Netduino runs on .Net micro framework. Currently, it does not support SSL. All the blogs I read said that SSL implementation takes up too much memory and Netduino does not have enough to support it. So, you cannot directly connect to the Azure Service Bus queue. Hopefully, someone will implement the SSL stack soon.

But if we modify the architecture a bit, we can overcome the SSL support issue. Here is the modified architecture that worked.


I added an additional layer which acted as proxy between the Netduino and the Service Bus. Instead of Netduino connecting to the Azure Service Bus Queue endpoint, Netduino connects to the WCF service implemented behind the firewall. The WCF service checks for messages in the Azure Queue and returns the messages to the Netduino.

By using the Azure Service Bus Queues, we don’t have to open up ports on our router or setup port forwarding. Doing so, opens our network for all kinds of attacks. Not being a security expert, I would rather have all incoming ports shut tight than try and implement an authentication mechanism.

ListViewWebPart – Set custom SPView (SharePoint 2013/2010)

by Amol Ajgaonkar

I was working on a feature stapler to add a list view on the landing page. I simply created an instance of the ListViewWebPart class, set the ListID, ViewGuid and the WebID and added the web part to the page. Great, I saw the web part on the page. But then, I realized that the web part was not rendering the view I had set.


Searching online, I found numerous articles describing how a ListViewWebPart works. To summarize, ListViewWebPart creates a hidden view and uses that view to render. So, even if you set the view while instantiating the web part, it does not use that view.

The solution for this was pretty simple, all I did was use the XSLTListViewWebPart instead of the ListViewWebPart and it used the view that I set. Here is a snippet of code that returns a XSLTListViewWebPart.

public static XsltListViewWebPart GetListWebPartWithViewFor(SPList list, string webPartTitle,string viewName)
XsltListViewWebPart lstWp = new XsltListViewWebPart();
SPView view = list.Views[viewName];
if (view != null)
lstWp.ViewGuid = view.ID.ToString();
lstWp.ViewGuid = list.DefaultView.ID.ToString();
lstWp.ListId = list.ID;
lstWp.WebId = list.ParentWeb.ID;
lstWp.Title = webPartTitle;
lstWp.ChromeType = System.Web.UI.WebControls.WebParts.PartChromeType.TitleOnly;

return lstWp;

Fifteen Mobility Improvements To Bring Your Field Staff Into The Now

by Sadie Van Buren

20140514_Field_Enablement_At_Meat_Spot_crop_sq_200   If your field workforce is up and running on a mobile device platform to do their work, congratulations! You’re already realizing the benefits of stepping away from a paper-based process. But is their mobile experience taking advantage of the latest and greatest functionality? Advancements in just the past two years have been so rapid that many of the functions that seemed revolutionary just a short time ago have been eclipsed. The field service experience no longer needs to be a disembodied app on a device – now the device can act as a Swiss Army knife of tools, as well as an extension of the desktop and your corporate systems.

I interviewed the experts on our Devices and Mobility team, and they shared with me fifteen mobility improvements you can take advantage of today, that will empower your field staff and make their work lives easier:

Functionality Then Now
1. E-signature capture Needing to sign on paper, or to use a dedicated device or stylus, which is challenging if it is lost, stolen, broken, or used in a slippery / greasy environment Sign with your finger.
2. GPS location detection Continual connection to wifi drains the battery.
Example: Needing to track vehicles during their delivery routes, or find equipment or inventory at a facility.
Get regular location updates without being continually connected.
3. Offline / disconnected data access Long, tedious waiting for app sync; inability to multitask. Sync in the background while you continue to work.
4. Cross-platform availability Locked into a single platform, heavy reliance on native code. Provide cross-platform availability with minimal native code.
5. Multiple functions in a single device Dedicated, proprietary devices that provide a single function.
Example: a retail organization having a separate device for everything the customer can do in their stores – price scanning, gift registry, etc.)
A single device that can support multiple use cases and functions.
6. Image capture Needing to carry a separate camera or switch to separate function.
Example: taking photos during a site inspection.
Hands-free data capture.
7. Audio capture Ambient environmental noise means poor recording quality.
Example: Elevator shaft inspection – making voice annotations while there is a loud hum in background.
Custom filters can provide background noise reduction as needed.
8. Data capture Manual data entry.
Example: Capturing environmental temperature at different times of day.
Sensors can report back to your app, eliminating manual data entry.
9. Scanning / barcode Scan individual items with a dedicated scanner. Walk into a room and anything with a Bluetooth low-energy signal can be captured.
10. Real-time streaming Streaming kills your cellular plan & battery life. Design apps to only stream on-demand; implement push notifications for background updates.
11. Screen Brightness Battery drain.
Example: Dim environmental lighting, for example at an inspection site, requires higher screen brightness.
Profile your app’s power consumption using tools; theme the UI to work well across ambient lighting conditions.
12. Dashboards Lacking the ability to receive alerts and act upon the information displayed. Sites are responsively designed and the computing power of the device is greater. Receive information, act upon information. See your dashboard on your phone.
13. Native applications Applications such as those in the MS Office suite opened in web browser version with varying results. The software becomes part of the tool. Applications such as PowerPoint can be opened and projected from the phone.
14. Personal assistant The automated PAs of two years ago produced varying results with limited functionality. Today’s functionality is much improved. Assistants like Siri, GoogleNow, and Cortana can analyze your calendar and help with reminders.
15. Segregation of enterprise / personal Needing to carry two devices Today’s mobile operating systems handle this nicely.

The Business Drivers of the Modern Application – Part 11: Conclusion

by Mikhail Shir

Consumer expectations are changing the way that corporations design, build and run applications.  Employees are increasingly asking their internal IT organizations to provide experiences that are similar to their consumer experiences with websites, devices and applications.

Successful IT organizations are addressing the need to support these increasing business demands by focusing on these pillars and dimensions:



They focus on experience, architecture and process to create successful modern applications.

Experience enables IT organization to deliver applications that operate the way that the user prefers to work instead of requiring the user to change to accommodate the applications.  This demonstrates to internal users that the technology team understands their needs and is responding by making their day-to-day activities simpler, more intuitive and more efficient.

Architecture enables IT organizations to deliver applications that can scale to meet the needs of the organization and eventually to external partners.  They also ensure that the user’s availability and security needs are met.

Process allows IT organizations to more effectively partner with their business counterparts to build applications.  Agile methodologies allow business partners to set priorities every few weeks instead of trying to create rigid yearly plans.  They also allow IT organizations to get direct feedback from the end users on what is working and what is not.  Breaking down those barriers helps to deliver better software faster to end users.

Thank you for taking the time to read the business drivers of modern applications.  We hope that this spurs discussion into how dramatically consumer demands have changed how we should be thinking about building and delivering applications.
