Bluetooth Barcode Scanner

- Dec 22, 2018 -

Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength UHF radio waves in the ISM band from 2.400 to 2.485 GHz from fixed and mobile devices, and building personal area networks (PANs). It was originally conceived as a wireless alternative to RS-232 data cables.

Bluetooth is managed by the Bluetooth Special Interest Group (SIG), which has more than 30,000 member companies in the areas of telecommunication, computing, networking, and consumer electronics. The IEEE standardized Bluetooth as IEEE 802.15.1, but no longer maintains the standard. The Bluetooth SIG oversees development of the specification, manages the qualification program, and protects the trademarks.[3] A manufacturer must meet Bluetooth SIG standards to market it as a Bluetooth device.[4] A network of patents apply to the technology, which are licensed to individual qualifying devices.

The name Bluetooth is an Anglicised version of the Scandinavian Blåtand/Blåtann (Old Norse blátǫnn), the epithet of the tenth-century king Harald Bluetooth who united dissonant Danish tribes into a single kingdom. The implication is that Bluetooth unites communication protocols.

The idea of this name was proposed in 1997 by Jim Kardach of Intel who developed a system that would allow mobile phones to communicate with computers. At the time of this proposal he was reading Frans G. Bengtsson's historical novel The Long Ships about Vikings and King Harald Bluetooth.

Since first invented ,Bluetooth version has developed from Bluetooth 1.0 to Bluetooth 5 ,and the most use in barcode scanners is Bluetooth 4.0

Bluetooth 4.0 has been adopted as of 30 June 2010. It includes Classic Bluetooth, Bluetooth high speed and Bluetooth Low Energy (BLE) protocols. Bluetooth high speed is based on Wi-Fi, and Classic Bluetooth consists of legacy Bluetooth protocols.


Bluetooth Low Energy, previously known as Wibree, is a subset of Bluetooth v4.0 with an entirely new protocol stack for rapid build-up of simple links. As an alternative to the Bluetooth standard protocols that were introduced in Bluetooth v1.0 to v3.0, it is aimed at very low power applications powered by a coin cell. Chip designs allow for two types of implementation, dual-mode, single-mode and enhanced past versions. The provisional names Wibree and Bluetooth ULP (Ultra Low Power) were abandoned and the BLE name was used for a while. In late 2011, new logos "Bluetooth Smart Ready" for hosts and "Bluetooth Smart" for sensors were introduced as the general-public face of BLE.


Compared to Classic Bluetooth, Bluetooth Low Energy is intended to provide considerably reduced power consumption and cost while maintaining a similar communication range. In terms of lengthening the battery life of Bluetooth devices, BLE represents a significant progression.


In a single-mode implementation, only the low energy protocol stack is implemented. Dialog Semiconductor, STMicroelectronics, AMICCOM,[70] CSR, Nordic Semiconductor and Texas Instruments[73] have released single mode Bluetooth Low Energy solutions.

In a dual-mode implementation, Bluetooth Smart functionality is integrated into an existing Classic Bluetooth controller. As of March 2011, the following semiconductor companies have announced the availability of chips meeting the standard: Qualcomm-Atheros, CSR, Broadcom and Texas Instruments. The compliant architecture shares all of Classic Bluetooth's existing radio and functionality resulting in a negligible cost increase compared to Classic Bluetooth.

Cost-reduced single-mode chips, which enable highly integrated and compact devices, feature a lightweight Link Layer providing ultra-low power idle mode operation, simple device discovery, and reliable point-to-multipoint data transfer with advanced power-save and secure encrypted connections at the lowest possible cost.

General improvements in version 4.0 include the changes necessary to facilitate BLE modes, as well the Generic Attribute Profile (GATT) and Security Manager (SM) services with AES Encryption.

As a wireless data transmit solution ,Bluetooth used widely in barcode scanners , the bluetooth barcode scanner connect to devices with build in bluetooth module ,or through a bluetooth data receiver to receive the data from the barcode scanner it paired .

A Bluetooth Barcode Scanner has many advantages over standard corded models. Because they are wireless, using a bluetooth barcode scanner allows more mobility while scanning barcodes. No longer tethered to the host device, you don't have to worry about cord length or the amount of space required on the work station. With a wireless connection, a bluetooth barcode scanner can be paired and used with practically any host that has a bluetooth radio. Consequently, laptops, phones, PC's and tablets all have the ability to integrate the bluetooth barcode scanner into work flow. And because there is no longer a cord and the need to make the scanner prominent on the work station, the physical size and designed ergonomics of a bluetooth barcode scanner can become smaller, more functional and incorporate the types of improvements users need for long sessions of scanning barcodes.

With a bluetooth barcode scanner, you can scan barcodes from up to 30 feet away. In many cases the wireless connection will be maintained through obstacles such as a wall or shelf.

There are 3 kinds of bluetooth barcode scanner available from Syble ,Laser bluetooth barcode scanner ,CCD bluetooth Barcode Scanner and 2D bluetooth barcode scanner,it meet different industries requirement,please consult with our engineer to choose the suitable bluetooth barcode scanner .
