Bluetooth Low Energy: THE COMPLETE GUIDE TO BLE PROTOCOL DEVELOPMENT: GATT Services, Advertising, Pairing, and IoT Device Implementation for Wearables

By: Sullivan, Eero

Design and ship BLE devices that connect reliably, transfer data efficiently, and stay maintainable as your firmware and apps evolve.

BLE can feel unpredictable when discovery, GATT design, security, and timing are treated as separate problems. Small mistakes in advertising payloads, caching behavior, operation sequencing, or pairing flows can turn into flaky connections, stalled transfers, and hard to reproduce field failures.

This book walks you through BLE protocol development end to end, from GAP and advertising through ATT and GATT mechanics, pairing and privacy, and into real product patterns for wearables, beacons, smart sensors, and gateways.
