Bluetooth is a simple radio solution
that allows different devices to talk to each other.
Since Bluetooth devices are radios, they can even communicate through walls or over distances of up to 100m.
'Personal Area Networking' aptly
describes Bluetooth's best feature - a mini personal network with devices in your
Some of the devices currently available in the market include:
Synchronize data quickly
and wirelessly between your Pocket PC, phone, and computer using Bluetooth.
More devices are disappearing on a regular basis from different companies.

are 3 classes of Bluetooth device defined to suit different needs:
Class 1 - Long Range Maximum Output Power of 100mW (20dBm)
Class 2 - Medium Range Maximum Output Power of 2.5mW (4dBm) most common
Class 3 - Short Range Maximum Output Power of 1mW (0dBm) very rare
A value of distance cannot be explicitly
stated for each device class; every user environment is slightly different,
and affects the signal in different ways. The best way to compare devices operating range is by comparing Output Power.
A device with a larger output power will be able to communicate with other devices over a further distance.
Most Brainboxes devices are class 1 devices with a very powerful Power Output,
Brainboxes Bluetooth Class 1 devices have one of the most powerful Bluetooth radios in the industry - 14dBm!
Bluetooth LE, BLE, marketed as Bluetooth Smart is a wireless personal area network technology designed and marketed by the Bluetooth Special Interest Group aimed at novel applications in the healthcare, fitness, beacons, security, and home entertainment industries.
Compared to Classic Bluetooth, Bluetooth Smart is intended to provide considerably reduced power consumption and cost while maintaining a similar communication range.
Bluetooth Smart was originally introduced under the name Wibree by Nokia in 2006.
It was merged into the main Bluetooth standard in 2010 with the adoption of the Bluetooth Core Specification Version 4.0.
Mobile operating systems including iOS, Android, Windows Phone and BlackBerry, as well as OS X, Linux, and Windows 8, natively support Bluetooth Smart. The Bluetooth SIG predicts that by 2018 more than 90 percent of Bluetooth-enabled smartphones will support Bluetooth Smart.
Bluetooth Smart is not backward-compatible with the previous, often called Classic, Bluetooth protocol.
The Bluetooth 4.0 specification permits devices to implement either or both of the LE and Classic systems.
Bluetooth Smart uses the same 2.4 GHz radio frequencies as Classic Bluetooth, which allows dual-mode devices to share a single radio antenna.
LE does, however, use a simpler modulation system.
In 2011, the Bluetooth SIG announced the Bluetooth Smart logo intended to clarify compatibility between low energy devices.
Bluetooth Smart Ready indicates a dual-mode device compatible with both Classic and low energy peripherals.
Bluetooth Smart indicates a low energy-only device which requires either a Smart Ready, or another Smart device in order to function.
The Bluetooth SIG identifies a number of markets for low energy technology, particularly in the smart home, health, sport and fitness sectors.
Advantages include: low power requirements, operating for "months or years" on a button cell;
small size and low cost; compatibility with a large installed base of mobile phones, tablets and computers

On the hardware front Brainboxes have developed a new Bluetooth serial port adaptor to enable dumb devices with RS232 serial connectors to connect wirelessly with other devices. lhb
The compact Brainboxes BL-819 is ideal for printers, scanners and other devices since it brings Bluetooth wireless technology to devices without the need to install any software.
The BL-819 Bluetooth v1.1 qualified adaptor is a Class 2 device (medium range), operating at 2dBm, which gives the device a maximum operating range of up to 30 metres.
A compact and very user friendly form factor with a size of only 7.5cmx3.4cm, and a weight of 24g means that the Bluetooth adaptor can be applied to a wide variety of peripherals.
Whilst the 9-pin RS232 based BL-819 adaptor does not require any software installation, the device can be easily configured via Windows or Linux systems via 3 simple and easy to use configuration utilities, without the need for a specific configuration application.
