Wi-Fi Connectivity a Boon for Mobile Developers

We’ve adjusted our routers over WiFi for a long time. Boot up the router, select the access point, punch into the browser, enter the admin user name and password and you’re in. What could be easier for the customer than filling out a few fields on a form and hitting Save? The cool thing is that you can get to your router interface using almost any WiFi-enabled device, from the lowly desktop and laptop all the way up through tablets and the latest smartphones. We take the process for granted.

House Remote Control AppToday, WiFi-connected devices are popping up all over the place, both stand-alones and others connected to local networks. If you’re a mobile developer, you might want to expand your scope to include a decent awareness of current WiFi-enabled technology and how it’s being used.

For example, take the FitBits Aria WiFi smart scale. It measures your weight, tracks your percentage of body fat, and can accommodate up to eight users. It also uploads your data to a FitBits account via WiFi and your network, so you can record and watch your progress. Set-up is accomplished using a Windows computer connected to your local network.

While the smart scale is interesting, it’s pretty tame compared to the Parrot 2.0 drone. This amazing piece of aeronautic/electronic/computer/software engineering has an on-board access point that you connect with via smartphone to control the craft and its flight profile. Not only can you fly the thing that way, you get a down-feed of what its cameras are seeing. You can also monitor important flight characteristics in real time. The flight computer is Linux-based and you have to ask yourself what kind of insane applications could you create to talk to the Parrot using your expertise in Android or iPhone development?

Getting Your Hands Dirty

Getting hands-on experience with WiFi-connected hardware has never been easier. And, the barrier to entry is extremely reasonable.

Combining an Arduino microcontroller with an XBee WiFi module is a straightforward exercise. You can buy an Arduino for about $20, an XBee breakout board for about $13 and the WiFi module for roughly $35. Parts are available through Sparkfun, Adafruit, O’Reilly and do-it-yourself electronics suppliers. Programming is done through the Arduino-integrated developer environment and Digi’s XBee configuration tools. (There’s a huge community built around the Arduino with lots of experts contributing to forums and discussions.)

If you want to move up to the next level of prototype WiFi-enabled devices, check out the upcoming SparkCore. It’s a Linux powered processor mated to an Arduino microcontroller and a WiFi radio module in the home stretch of development. The pre-order price is about $40 with estimated delivery sometime in October. According to the specs, the little device comes configured to run a standalone access point that allows connections from nearby smartphones, tablets and other devices.

WiFi-enabled devices look like a rich area of opportunity for developers and new product designers. Using off-the-shelf components, such as the Arduino and SparkCore is certainly a quick, viable way to create proof-of-concepts along with your cutting-edge iPhone or Android applications.

As the price of such little, special purpose but easily configured modules comes down, we’ll see a lot of interest in creative new products. If you’re looking to get out in front of mobile development, this is an approach worth thinking about.
