If you were wondering why manufacturers seemed to be rather slow in launching HomeKit-compatible devices, it may all be down to Apple’s stringent security requirements. Forbes reports that manufacturers are finding it hard to incorporate the extremely secure encryption standards demanded by Apple in order to achieve MFi certification for their products.
Apple is requiring device makers using both WiFi and Bluetooth LE to use complicated encryption with 3072-bit keys, as well as the super secure Curve25519, which is an elliptic curve used for digital signatures and exchanging encrypted keys.
While mains-powered WiFi kit is coping, the processing workload in battery-powered Bluetooth LE devices is leading to extremely slow response times, say manufacturers … expand full story

Two of the hottest product categories at this year’s CES were home automation and wearables, which Apple is now tackling with HomeKit and the Apple Watch. As has historically been the case, the price premiums Apple has set for its products have left plenty of room for more affordable alternatives. Misfit, a company co-founded by former Apple CEO John Sculley, is now competing in both categories: the just-released Bolt Wireless LED Smart Light Bulb ($50) joins a small collection of Bluetooth-controlled lights, while its late 2014 wearable fitness and sleep tracker Flash ($33-$50) is in the process of being upgraded to control Bolt.
Misfit’s pitch for Bolt is interesting. It’s billing the color-shifting bulb as producing “gallery-quality light,” and focusing its new Misfit Home app for iOS on creating “Lightscapes” — lighting scenarios including neutral bright white, warm sunrises and sunsets, candlelight, forest and volcanic tones, amongst other “scenes” where the color is set but the brightness is adjustable. When Bolt works, it’s a wonderful source of light, but as is common these days, some post-release tweaks will be needed to exploit its full potential…

Two years ago, the Tile Bluetooth tracking device raised over $2.6 million in a crowdfunding campaign, thanks in part to an expansive ad run that seemed to blanket the entire Internet. Elegantly designed with a square plastic housing, Tile paired a low-energy Bluetooth chip with a battery, letting you track any attached item using a Bluetooth 4-enabled iPhone. Each Tile can track keys, a purse, or even a roaming pet for a year before the battery dies, at which point you are supposed to replace it. The first Tiles shipped last year, and can now be had for $20 each versus their standard $25 retail price.
I skipped Tile because I don’t like products that need to be replaced when their batteries die. Over the course of reviewing thousands of Apple accessories, I’ve watched some companies waste vast quantities of plastic, metal, magnets, and packing materials, and I try not to buy things that are designed to be worthless after a short period of time. (Note: Users are encouraged to recycle Tiles by buying discounted replacements and mailing old units back to the company.) So a new Tile competitor called TrackR Bravo ($29) appealed to me. Made partially from anodized aluminum, it’s shaped like a dog tag and designed to be kept rather than tossed away. The core functionality is the same as Tile’s, but Bravo’s battery can be replaced with ease. You can also use Bravo to locate a misplaced iPhone, and optionally sound a separation alarm whenever your iPhone and Bravo get too far away from one another…

The Jawbone UP bracelet has been on the market for three years receiving improvements every year. The Jawbone UP 24 received a major update: Bluetooth LE. Initially to sync the data onto the phone, the user had to plug the band into the phone’s headphone jack and wait, typically about fifteen seconds, for the data to sync into the app.
Now, since the UP 24 has Bluetooth LE capabilities, it is compatible with the iPhone 4S and later, the fifth generation iPod Touch, the third generation iPad and newer as well as the iPad Minis. Jawbone has made the UP 24 to be compatible with Android phones. Bluetooth LE allows the band to automatically connect with the Jawbone UP app.
