The First Complete Guide to Bluetooth Low Energy: How It Works, What It Can Do, and How to Apply It

 

A radical departure from conventional Bluetooth technology, Bluetooth low energy (BLE) enables breakthrough wireless applications in industries ranging from healthcare to transportation. Running on a coin-sized battery, BLE can operate reliably for years, connecting and extending everything from personal area network devices to next-generation sensors. Now, one of the standard’s leading developers has written the first comprehensive, accessible introduction to BLE for every system developer, designer, and engineer.

 

Robin Heydon, a member of the Bluetooth SIG Hall of Fame, has brought together essential information previously scattered through multiple standards documents, sharing the context and expert insights needed to implement high-performance working systems. He first reviews BLE’s design goals, explaining how they drove key architectural decisions, and introduces BLE’s innovative usage models. Next, he thoroughly covers how the two main parts of BLE, the controller and host, work together, and then addresses key issues from security and profiles through testing and qualification. This knowledge has enabled the creation of Bluetooth Smart and Bluetooth Smart Ready devices.

 

This guide is an indispensable companion to the official BLE standards documents and is for every technical professional and decision-maker considering BLE, planning BLE products, or transforming plans into working systems.

 

Topics Include

  • BLE device types, design goals, terminology, and core concepts
  • Architecture: controller, host, applications, and stack splits
  • Usage models: presence detection, data broadcasting, connectionless models, and gateways
  • Physical Layer: modulation, frequency band, radio channels, power, tolerance, and range
  • Direct Test Mode: transceiver testing, hardware interfaces, and HCI
  • Link Layer: state machine, packets, channels, broadcasting, encryption, and optimization
  • HCI: physical/logical interfaces, controller setup, and connection management
  • L2CAP: channels and packet structure, and LE signaling channels
  • Attributes: grouping, services, characteristics, and protocols
  • Security: pairing, bonding, and data signing
  • Generic Access Profiles: roles, modes, procedures, security modes, data advertising, and services
  • Applications, devices, services, profiles, and peripherals
  • Testing/qualification: starting projects, selecting features, planning, testing, compliance, and more

《第一本完整指南:藍牙低功耗技術:工作原理、功能及應用方法》

藍牙低功耗技術(BLE)是一種與傳統藍牙技術截然不同的革命性技術,可在從醫療保健到交通運輸等各個行業實現突破性的無線應用。BLE可在一個硬幣大小的電池上可靠運行多年,連接和擴展從個人區域網絡設備到下一代感測器的一切。現在,該技術的領先開發者之一為每個系統開發人員、設計師和工程師撰寫了第一本全面、易於理解的BLE入門指南。

藍牙SIG名人堂成員Robin Heydon匯集了以前分散在多個標準文件中的重要信息,分享了實施高性能工作系統所需的背景和專家見解。他首先回顧了BLE的設計目標,解釋了這些目標如何影響了關鍵的架構決策,並介紹了BLE的創新使用模型。接下來,他詳細介紹了BLE的兩個主要部分,控制器和主機,以及從安全性和配置文件到測試和認證的關鍵問題。這些知識使得藍牙智能和藍牙智能就緒設備的創建成為可能。

這本指南是官方BLE標準文件的必不可少的伴侶,適用於每個考慮使用BLE、計劃BLE產品或將計劃轉化為工作系統的技術專業人員和決策者。
