Ever wondered why they named the most universal wireless technology Bluetooth? Apparently it was named after a 10[SUP]th[/SUP] century Danish King named Harald Blåtand whose nickname was Bluetooth because one of his teeth was blue. King Bluetooth’s claim to fame is that he helped peacefully unite Norway, Sweden, and Denmark. Since Bluetooth was created by Ericsson (a Swedish company) and it allows you to share voice, data, music, photos, and other warring factions amongst our mobile devices I get the naming convention, absolutely.
Bluetooth is awirelesstechnology standard for exchanging data over short distances (using short-wavelengthUHF radio wavesin theISM bandfrom 2.4 to 2.485 GHz) from fixed and mobile devices, and buildingpersonal area networks(PANs). Invented by telecom vendorEricssonin 1994, it was originally conceived as a wireless alternative toRS-232data cables. It can connect several devices, overcoming problems of synchronization (Bluetooth 101).
The latest version is called Bluetooth Smart which is an extension of the original Bluetooth brand focused on low power implementations. Think IoT and wearables where you want to go days, months, or even years on a single charge of a tiny battery.
Bluetooth Smart provides a very low power, low MIPs & low gate count platform for applications requiring Single Mode Bluetooth Low Energy (BLE), e.g. smartwatches, hearing aids, wearable sensors for medical /sports (heart rate, glucose, temperature), remote controls, toys, environment sensors, location beacons and many other machine–machine communications (CEVA RivieraWaves Bluetooth Platforms).
As you can imagine, Bluetooth Smart applications are exploding as are the presentations on Bluetooth. The latest and greatest one I have seen is from Dialog Semiconductor (they just acquired Atmel) presented on September 16[SUP]th,[/SUP] 2015 at Capital Markets Day in London. The presentation title is Personal Portable Connected and in 22 PDF pages it covers Bluetooth Smart: Market update, product update, and key takeaways.
*Spoiler alert* Here is the Bluetooth® Smart market size:
And here are the 5 uses of Bluetooth Smart Technology that you probably didn’t know compliments of CEVA:
1.) Nest Thermostat Gen 3 and Nest Protect Gen 2, the latest generation Thermostat and Protect devices from Nest both include Bluetooth Smart Connectivity in order to simplify maintenance and control of these devices to your smartphone:
2.) Salt Card, a a Keyless Entry Method for Smartphones. With the SALT card, which is in the shape of a credit card, users will no longer need to enter their pin or pass codes while within 10ft. of the card, as the device and card wirelessly sync thanks to Bluetooth Smart technology:
3.) Li-Ning Smart Trainers, Xiaomi’s smart trainers, designed by Sportswear brand Li Ning are available in China now. Bluetooth Smart chips are the solo of the trainer and send information to Xiaomi’s existing Mi Fit app on your smartphone, measure steps taken and calories:
Eizo ‘Foris’ Gaming Monitor, With the Bluetooth connectivity built into the monitor, gamers are able to use their mobile devices to adjust the colour, brightness, gamma and other settings, and to post a notification in the corner of the screen when a call or message arrives on their smartphone:
