AIROC™ BTSDK - CYW20721

Overview

The Infineon CYW20721 is an ultra-low-power dual-mode Bluetooth® 5.4 wireless MCU device. It has a stand-alone baseband processor with an integrated 2.4 GHz transceiver supporting LE/BR/EDR.

SDK Software Features

  • Dual mode Bluetooth® stack included in the ROM (BR/EDR and LE).
  • Bluetooth® stack and profile level APIs for embedded Bluetooth® application development.
  • AIROC™ HCI protocol to simplify host/MCU application development.
  • APIs and drivers to access on board peripherals.
  • Bluetooth® protocols include GAP, GATT, SMP, RFCOMM, SDP, AVDT/AVCT
  • LE and BR/EDR profile APIs, libraries, and sample apps.
  • Support for Over-The-Air (OTA) upgrade.
  • Device Configurator for creating custom pin mapping.
  • Bluetooth® Configurator for creating LE GATT Database.
  • Documentation for APIs, datasheet, profiles, and features.
