Digi Goes to Nuremberg for Embedded World 2016

Posted on:

At last week’s Embedded World, we made two exciting announcements. First off, this summer we’ll begin shipping the ConnectCore 6UL development kits. This tiny module, based on the NXP i.MX6UL processor, is just 29mm x 29mm. The CC6UL’s low-power consumption combined with high performance and easy wireless integration will make the module a true game-changer in the Industrial IoT space. More info on the ConnectCore 6UL module is available here.

cc6ul-dimensionsWe also announced a new XBee module in order to support the emerging wireless protocol, Thread. The module will be made available this spring and allow our customers to start designing and testing Thread networks. Thread is an exciting new wireless standard created to improve network reliability, security and power efficiency. We are extremely excited about this new member to the XBee family.

Customer Demos
In our booth, we shared the numerous ways our customers are using Digi embedded technology today. Featuring the ConnectCore 6 module, we had our customers Fraser Nash and Furuno on display. Fraser Nash builds zero-emissions taxi cabs for the city of London, while Furuno provides a next-generation platform for commercial marine navigation. Watch the video below to see the Furuno demo in action.

Another fun demo we had was the Parallax ELEV-8 Quadcopter. The quadcopter is equipped with an XBee based telemetry system. Along with the quadcopter, Parallax provides free software to graphically view data from the device such as battery voltage, pitch, orientation, throttle position, and much more. Attendees could power up the quadcopter, pick it up, adjust the throttle, and see all of the telemetry data streaming live on a laptop.

Digi Partners
As we explored the show floor we found an awesome IoT demo in the Digi-Key Electronics booth. It was a wireless sensor network application featuring XBee, Nimbelink cellular module, BeagleBone board, and the Exosite cloud platform. This was truly an end-to-end IoT solution from sensor to cloud.

And just 5 steps away from that end-to-end IoT demo was a wireless charging demo which used XBee to send display information and charging status data between the two devices.

Digi’s Golden Birthday: Celebrating 30 Years of Connected Technology

Posted on:

Today marks Digi’s golden birthday! Over the last 30 years, a lot has changed and more is on the way, so for a little fun, we decided to take a look back at Digi’s history. When was XBee invented? When did the Digi diamond logo come into existence? All those answers and more are below. Here’s to 30 more years!

Digi Employee Hackathon: Lindon Edition v2

Posted on:

Another Digi employee hackathon has come to a close! Rob paid a visit to our team out in Utah to hold a hackathon with Digi’s development staff. This continues what has become a tradition at Digi over the last couple years.

Each event has led to the creation of a number of product improvements and other fun and whimsical projects. Another important benefit is that it gives everyone a chance to collaborate with those they don’t normally work with on a day-to-day basis.

Here’s a look at the winning project.

AT Command Database
The winners of our recent hackathon created an incredibly useful tool for both developers inside our company and for our customers. The team’s final prototype is a new centralized system for managing XBee, XTend and our other radios’ AT command info across our entire wireless product line. Digi’s wireless products use these AT commands to manage setup, networking, security, sensors, actuators, battery use, diagnostics and many more functions.

There are hundred of useful commands that need to be managed, tested and shared between our products, libraries, software and documentation. In addition, the commands are implemented by our partners in third-party products and tools. Changes, updates and corrections to the commands need to be kept in sync across all these implementations, and absolute accuracy is essential.

IMG_7064

Prior to Team AT-DB’s creation, the process for maintaining up-to-date AT command information involved lots of coordination and double-checking. We also needed a more efficient way to accurately process updates when changes occur, and share these with our partners and customers. Each command has a specific syntax, description, parameters and defaults. Certain commands must be implemented differently for different protocols. Details matter!

Here are the main benefits the group demonstrated with their new prototype:

  • The ability to audit radio descriptors and test firmware updates against a single, authoritative source.
  • Automatic synchronization services for Digi software like XCTU, and also for third-party software development partners.
  • Electronic documentation support functions and enhanced support for automated testing.
  • A user friendly front end interface that can be enhanced as new use cases arise.

Hackathons keep us creative and excited about our work as it’s an opportunity to try out new ideas. Successful prototypes like this one inspire and help implement the innovative systems necessary to making and maintaining Digi’s mission-critical products.

Devergy Expands Solar Power Possibilities in Africa

Posted on:

Did you know that roughly 1.7 billion people are not connected to a power grid? In Sub-Sahara Africa, the number is around 500 million. For many, the infrastructure simply doesn’t exist. The modern day conveniences we take for granted such as being able to read at night, cooking on the stove top and refrigeration can be a hassle, or close to impossible, with no access to a reliable source of electricity.

The challenges of installing a power grid in remote and undeveloped areas can be numerous, so how do we reimagine how to deliver reliable electricity and move past the traditional power grid system? Thankfully, Devergy is solving this tricky problem. Using solar power and wireless technology, Devergy has built a sustainable business that’s helping villages in Tanzania and Ghana meet their energy needs.download

Who is Devergy?
Founded in 2010 by Fabio De Pascale, Gianluca Cescon and Daniel Ponz, Devergy is a social enterprise committed to providing an affordable and reliable source of energy to low-income people throughout Tanzania.

Their customers live in rural areas of the country where a power grid is nonexistent and residents do not have the money necessary to purchase a personal solar home system.

Residents in Tanzania typically spend between 6 and 25 USD per month on kerosene, phone charging, and dry-cell batteries for radios. After the installation of Devergy’s solar grids, residents spend as much as 20% less than what they were spending on kerosene for lighting and 50% less for phone charging. Not only does Devergy provide a clean, renewable and reliable source of energy, but it’s also substantially more affordable.

The service is based on village-sized energy micro-grids, which provide solar power to households and small businesses; it allows the users to connect lights and appliances such as radios, TVs and refrigerators. With the smart micro-grids, the usage of installed power is up to 70% more efficient than with equivalent solar home systems.

The key feature of the system is an energy meter that powers the household or business with a pre-paid pay-per-use approach, where customers top up their credit by using a mobile commerce platform, such as Vodacom M-Pesa. This is just like the system you would use to top-up a pre-paid mobile phone.

How it Works
Devergy uses Digi XBee technology for the communication network in its grids. Hundreds of nodes are connected with XBee–making the solar micro-grids smart, cost effective, and manageable. Devergy relies on XBee modules for its smart meters and is using Digi’s ConnectPort X4 for its ZigBee to GPRS gateways. Fabio, co-founder of Devergy says, “The plug and play, flexible nature of the Digi product was fundamental to get our services to the market faster.”

[meteor_slideshow slideshow=”Devergy”]
Devergy’s customers receive an unprecedented service thanks to a system that is designed to require no user maintenance and is remotely monitored for faults, so that the reliability and availability of the service is unmatched. Local representation of the company is ensured by the appointment of a village agent, selected based on recommendation by the village committee and trained by Devergy to perform technical support and sales. This ensures the customers always have a well-known and trusted counterpart to deal with.

Devergy has successfully connected more than 800 customers since 2012 to reliable, clean and safe electricity with a service sufficient to satisfy their needs for many years to come.  Currently, they are active in two regions and quickly growing their customer base. In addition to Tanzanaia, the Devergy grids are also licensed to third parties in Ghana, where they power 3 villages.

A Simpler and More Intelligent Internet of Things with Digi and Temboo

Posted on:

The ongoing drought in the western United States underscores the importance of maintaining and conserving a reliable supply of fresh water—whether for drinking, irrigation, fire control or manufacturing, reliable water storage is essential. Of course, half the battle in maintaining a water supply is managing it: once a tank system has been installed and filled, water must be properly distributed when it is needed and retained when it is not. If tanks are remote and many are spread over a wide area, monitoring them can become a costly and time-consuming obligation.

Screen Shot 2014-09-04 at 12.03.09 PMThese are the sorts of challenges that Digi and Temboo are overcoming by building a more intelligent Internet of Things. A network of Digi hardware running Temboo Choreos is flexible and smart—devices can be programmed to execute a wide variety of processes, and be reprogrammed without being interrupted. This is a solution that combines ease of automation with the trustworthiness of manual control. To illustrate the solution’s benefits, and demonstrate how the whole system works, we’ve built a model of the water tank problem. This system puts Temboo and Digi to work, keeping water levels right where they ought to be.

Our tank monitoring solution uses an XBee ZigBee radio to wirelessly exchange sensor information and remote control commands using Digi’s new XBee Gateway, a programmable device that joins ZigBee mesh networks to the Internet. A small Temboo client written in Python is installed on the XBee Gateway, allowing it to connect to over one hundred different web services using Temboo Choreos. With Temboo, the memory constraints of the small devices in the network cease to be an obstacle to intelligent behavior, as much of the code required to execute complex processes is offloaded to the cloud.

In our model, a sensor attached to the XBee radio monitors the water level of our tank, and sends those readings to the XBee Gateway. If the tank leaks and the water level falls, a response is triggered on the gateway. First, the gateway uses Temboo’s Yahoo Weather Choreos to check the forecast for rain. Temboo’s Nexmo Choreos are then used to telephone the relevant individual with an automated voice message that gives a real time rain forecast and offers a choice of actions to take by entering a number on the phone’s keypad.

Screen Shot 2014-09-04 at 11.56.33 AMIf a storm is on its way, there is an option to ignore the alert. If the leakage does not need to be urgently addressed, there is an option to schedule a maintenance event for the future, which the Temboo program on the gateway handles via a Google Calendar Choreo . If the situation is urgent, however, there is another option to activate a backup pump at a different point in the XBee network and refill the tank.  Of course, all of this will only work properly if the sensor and gateway are powered on and functioning, so our system needs to be prepared for any loss of connectivity—if, for any reason, transmission of the level of water in the tank stops, another Temboo Choreo will file a Zendesk ticket to alert support that the system needs attention.

The most exciting thing about this model, however, is that it is only a small example of a massively scalable system. XBee technology can connect hundreds of different devices in a much larger network, and Temboo’s Library contains over two thousand other Choreos that can be used to execute an immense variety of tasks. Modifying the behavior of the Temboo program on the gateway to, for example, switch notification services is just a matter of changing Choreos, a simple task.  Digi’s hardware and Temboo’s software are coming together to build a lighter, smarter and much easier to use Internet of Things.
