Marketing drops the point number; so that it is just "Bluetooth 5" (unlike Bluetooth 4.0); the change is for the sake of "Simplifying our marketing, communicating user benefits more effectively and making it easier to signal significant technology updates to the market." Bluetooth 5 provides, for BLE, options that can double the data rate (2 Mbit/s burst) at the expense of range, or provide up to four times the range at the expense of data rate. The data rate of EDR is 3 Mbit/s, although the maximum data transfer rate (allowing for inter-packet time and acknowledgements) is 2.1 Mbit/s. EDR uses a combination of GFSK and phase-shift keying modulation (PSK) with two variants, π/4-DQPSK and 8-DPSK. EDR can provide a lower power consumption through a reduced duty cycle. The specification is published as Bluetooth v2.0 + EDR, which implies that EDR is an optional feature. Aside from EDR, the v2.0 specification contains other minor improvements, and products may claim compliance to "Bluetooth v2.0" without supporting the higher data rate. Later, Motorola implemented Bluetooth in its own devices, which initiated significant propagation of Bluetooth in the public market, due to Motorola's larger market share vs Ericsson at the time. In 2012, Jaap Haartsen was nominated by the European Patent Office for the European Inventor Award. Bluetooth operates at frequencies between 2.402 and 2.480 GHz, or 2.400 and 2.4835 GHz, including guard bands 2 MHz wide at the bottom end and 3.5 MHz wide at the top. This is in the globally unlicensed (but not unregulated) industrial, scientific and medical (ISM) 2.4 GHz short-range radio frequency band. Bluetooth uses a radio technology called frequency-hopping spread spectrum. The above excludes Bluetooth Low Energy, introduced in the 4.0 specification, which uses the same spectrum but somewhat differently. A master BR/EDR Bluetooth device can communicate with a maximum of seven devices in a piconet (an ad hoc computer network using Bluetooth technology), though not all devices reach this maximum. Older Bluetooth hardware may receive 4.2 features such as Data Packet Length Extension and improved privacy via firmware updates. The Bluetooth SIG released Bluetooth 5 on 6 December 2016. Its new features are mainly focused on new Internet of Things technology. Sony was the first to announce Bluetooth 5.0 support with its Xperia XZ Premium in Feb 2017 during the Mobile World Congress 2017.

What is Bluetooth 4.0? Bluetooth Smart and Smart Ready Explained ...

Using that analogy, the drone ships are Bluetooth Smart devices. These peripherals connect to Bluetooth Smart Ready smartphones, tablets, and notebooks. Bluetooth Smart gadgets can also remain paired with Smart Ready devices even when they’re not used for hours or days at a time. So if you want to take advantage of Bluetooth 4.0’s new low-power capabilities, get ready to go shopping—you’ll need a new Bluetooth Smart Ready phone, computer, or tablet in addition to a Bluetooth Smart accessory or peripheral. ... As of press time, the Apple MacBook Air and the Mac Mini desktop were the only Bluetooth Smart Ready computers. Bluetooth is a technology people know but don’t necessarily love. That’s because Bluetooth gadgets can be tough to pair, and they tend to run out of juice too quickly. Bluetooth 4.0—or Bluetooth Smart—gives the standard a brain transplant. The new specification uses improved technology that helps everyday gadgets stay paired longer while using less power. Does Bluetooth 4.0 Make Existing Bluetooth Products Obsolete?

Bluetooth 4.0: What is it, and does it matter? - CNET

It’s still early days for Bluetooth 4.0. As we mentioned, the iPhone 4S is currently the only phone to have this specification, and there aren’t that many Bluetooth 4.0 devices yet to make use of the technology. Still, we should see more Bluetooth 4.0-compatible products before the end of the year, with more phones adopting the standard as well. According to Mike Foley, executive director of the Bluetooth SIG (Special Interest Group), the key new feature of Bluetooth 4.0 is its low-energy technology. This lets device manufacturers replace proprietary sensor technology with Bluetooth, which is a more widely adopted standard. Our expert, award-winning staff selects the products we cover and rigorously researches and tests our top picks. If you buy through our links, we may earn a commission. The recently announced iPhone 4S comes with Bluetooth 4.0, which is a first for mobile phones. One of the lesser-known facts to emerge about the iPhone 4S yesterday is that it is the first phone to launch with Bluetooth 4.0, the latest version of Bluetooth. Not many products are available with Bluetooth 4.0 just yet–in fact, two of the most recent products to ship with Bluetooth 4.0 are also from Apple: the MacBook Air and the Mac Mini.

Bluetooth 4.0: An introduction to Bluetooth Low Energy-Part II ...

The lower part of the stack, a controller, handles time consuming functionality and it’s often combined together with a physical radio. HCI provides a standardized interface between the Bluetooth LE controller and an arbitrary MCU which is hosting the application and the upper part of the stack. If both parts of the stack are collocated on the same MCU, e.g. sensor SoC, HCI is not used. Since Bluetooth as a technology has been around for a while, a number of publications describing stack functionality are available [4]. Therefore, discussion of the stack will be limited to the Bluetooth LE portion of the stack. This article intentionally omits a discussion of BLE applications for two reasons: first, it is a subject worthy of an article itself since BLE brings the possibility to connect new types of devices that can be smaller, cheaper and do not require rechargeable batteries, to virtually every cell phone; second, it was demonstrated that a good amount of new application ideas are generated while people explore new technology. From a development point of view, few Bluetooth LE chips are available now. TI introduced the CC2540 which is a complete SoC with a Bluetooth LE compatible radio and 8051 processor architecture. One of the main benefits of Bluetooth technology is device interoperability. A Bluetooth logo on a device guaranties that products from different suppliers having the same profile will understand each other. To assure this, it’s not enough to use a standardized wireless protocol to transfer bytes of information, but data representation levels must be shared as well. While Bluetooth 2.0 EDR or Bluetooth 3.0 HS introduced a higher data rate functionality, Bluetooth 4.0 targets effective communication with devices that do not need streaming data or high data throughput. Low-energy requirements stipulate noticeable differences in Bluetooth and Bluetooth LE protocols, but at the same time take great advantage in reuse of the RF part, leaving most of the changes to the protocol stack.
