Bluetooth Tutorial

'Bluetooth Tutorial: Design, Protocol and Specifications for BLE - Bluetooth Low Energy 4.0 and Bluetooth 5' starts from the ground up for a new user and does a gradual progression into the technical details around Bluetooth technology. The latest update adds information about Bluetooth 4.0 also known as Bluetooth Low Energy(BLE) and Bluetooth 5.0.

IntroductionBluetooth is the name given to a new technology standard using short-range radio links, intended to replace the cables) connecting portable and/or fixed electronic devices. The standard defines a uniform structure for a wide range of devices to communicate with each other, with minimal user effort.

Bluetooth key features are robustness, low complexity, low power and low cost. The technology also offers wireless access to LANs, PSTN, the mobile phone network and the Internet for a host of home appliances and portable handheld interfaces.

The immediate need for Bluetooth came from the desire to connect peripherals and devices without cables. The available technology-IrDA OBEX (Infrared Data Association Object Exchange Protocol) is based in infrared links that are limited to line of sight connections.

Bluetooth is further fueled by the demand for mobile and wireless access to LANs, Internet over mobile and other existing networks, where the backbone is wired but the interface is free to move. This not only makes the network easier to use but also extends its reach.
