規格化団体 Bluetooth SIG が、Bluetooth 4.0 製品向けの新ブランド " Bluetooth Smart " / " Bluetooth Smart Ready " を発表しました。v4.0から導入された低消費電力モードとの互換性をロゴで区別するためのもので、対応表は上の図のとおり。あえてそのまま書けば、

  • Bluetooth Smart Ready は:Bluetooth Smart Ready どうし、または無印 Bluetooth、またはBluetooth Smart の全種類に対応。
  • Bluetooth は:Bluetooth Smart Readyと、または無印 Bluetooth どうしで接続可能。Bluetooth Smart とは非互換。
  • Bluetooth Smart は:Bluetooth Smart Ready 機器とのみ接続可能。

「スマート」が付くと無印と互換性がなくなるのは直感的ではありませんが、このスマートは計測した数値を自分で喋って報告できるスマートセンサなどの「スマート」。要は心拍計やウェアラブルアクセサリなど、ボタン電池でも長時間駆動する低速・低消費電力モード(Bluetooth Low Energy)機器に対応するかどうかを示しています。別の書き方をすれば、

「心拍計など、特定の情報を集めて低消費電力モードで送る子機なら" Bluetooth Smart "」
「低消費電力モードの子機に対応し、従来のBluetooth 機器ともつながるデュアルモードの親機なら " Bluetooth Smart Ready "」
「低消費電力モードに互換性のない、従来通りの端末が " Bluetooth " 」

の三種類。たとえば発売されたばかりの iPhone 4S は "Bluetooth Smart Ready " 機器にあたるため、フィットネス向けのセンサーなどのアクセサリと(通信規格としては)互換性があります。一方、たとえばスマートフォンと連携するBluetooth 腕時計の新モデルが発表されても、通信形式に" Bluetooth Smart " と書いてあれば、従来の普通のBluetooth 携帯などとは互換性がないことになります。


Market and Use Case Expansion Create Need to Denote Compatible Bluetooth v4.0 Devices

KIRKLAND, WA – Oct. 24, 2011 – The Bluetooth Special Interest Group (SIG) announced two new brand extensions to its globally recognized logo today in an effort to create consumer awareness around compatibility for new devices implementing Bluetooth v4.0 – the Bluetooth Smart Ready trademark and the Bluetooth Smart trademark. Bluetooth Smart Ready devices are phones, tablets, PCs and TVs that sit at the center of a consumer's connected world and implement a Bluetooth v4.0 dual mode radio. Bluetooth Smart devices are sensor-type devices like heart-rate monitors or pedometers that run on button-cell batteries and were built to collect a specific piece of information. Bluetooth Smart devices include only a single-mode low energy Bluetooth v4.0 radio.

Bluetooth Smart Ready devices can connect to the billions of Bluetooth devices already in use today and also to new Bluetooth Smart devices just starting to enter the market. Bluetooth Smart devices, due to their revolutionary low power consumption, will only connect with products denoted with the Bluetooth Smart Ready mark, plus those designated specifically by product manufacturers.

"Here's the truth of the matter: Bluetooth Smart and Smart Ready devices will revolutionize the way we collect, share and use information," said Michael Foley, Ph.D., executive director of the Bluetooth SIG. "In order to ensure consumers know what these extraordinary devices have to offer, we created the Bluetooth Smart and Smart Ready marks. These new logos will help consumers manage compatibility, and encourage manufacturers to build their best Bluetooth devices yet."

A recent In-Stat report forecasts Bluetooth device shipments will exceed two billion in 2013 alone, fueled largely by the rapid introduction of Bluetooth Smart devices across many different industry segments.

"Consumers can look at new Bluetooth Smart Ready devices the same way they would a 3D ready TV – having the TV is just the first part of the puzzle, you need glasses and content in order to really experience 3D," said Suke Jawanda, CMO of the Bluetooth SIG. "Once consumers have a Smart Ready device, like the new iPhone 4S, they can continue connecting to existing Bluetooth devices and are also ready to experience the new world of Bluetooth Smart peripheral devices that will carry the Bluetooth smart logo."
