А Bluetooth radio module works by following standardized communication protocols that ensure compatibility between devices. These protocols define how data and audio are transmitted, making Bluetooth reliable for both consumer and industrial applications.

Classic Bluetooth Protocols:

Спп (Профиль серийного порта) – For serial data transfer.

HFP/HSP – For voice calls in car kits and headsets.

A2DP/AVRCP – For high-quality stereo music and audio control.

PBAP/MAP – For phonebook and message access in automotive systems.

Bluetooth низкая энергия (Бле) Протоколы:

ГАТТ – Core framework for data exchange.

АНКС – Apple Notification Center Service for iOS.

HRP/HTP/BLP – For healthcare devices like heart rate monitors and thermometers.

Plxp – For pulse oximeters.

By supporting both Classic and BLE protocols, двойной режим Bluetooth radio modules provide maximum flexibility. They can stream audio, enable hands-free calling, and support IoT health devices — all within one module.

Кроме того, Bluetooth protocols evolve with each version upgrade. Например, Bluetooth 5.0 and above bring higher data rates, extended range, and improved broadcast capacity, while Bluetooth 5.1 introduces centimeter-level positioning features. These updates ensure that Bluetooth radio modules remain future-ready for advanced applications in IoT, Умные дома, and next-generation wireless audio.

Для разработчиков, understanding protocols is crucial when selecting the right module. A module optimized for A2DP and AVRCP will be perfect for speakers or headphones, while modules with GATT and healthcare profiles are better suited for medical or wearable devices. Choosing the correct Bluetooth radio module ensures faster development, более низкие затраты, and a more reliable end product.
