Application Brief


The TI dual-mode CC2564C solution is a complete Bluetooth® BR/EDR/LE HCI or Bluetooth + Bluetooth low energy solution that reduces design effort and enables fast time to market.

A royalty-free software Bluetooth stack, available from TI, is pre-integrated with a variety of platforms including TI’s MSP432™ Arm® Cortex®-M4 core MCUs and Linux® Sitara™ MPUs. The stack is also available for MFi solutions and non-TI MCUs. Examples of profiles supported today include: Serial Port Profile (SPP), Human Interface Device (HID), Advanced Audio Distribution Profile (A2DP), Audio/ Video Remote Control Profile (AVRCP), Health Device Profile (HDP) and several Bluetooth low energy profiles (vary based on the supported MCU).

CC2564C and the TI software stack provide a fully certified Bluetooth 4.2 solution (5.1 compliant), including:

  • LE Secure connections: Bluetooth 4.2 security algorithm (ECDH) for key generation and new pairing procedure for key exchange
  • Link Layer topology: Bluetooth 4.1 scatternet capabilities, managing connection in a dual-mode topology allowing sensor network topology
