Flexible and robust dual-mode Bluetooth device with added security features

Texas Instruments’ newest, dual-mode Bluetooth device, CC2564C with Bluetooth 4.2 is an ideal solution for POS, medical and wearable devices. The device’s updated design features the advanced Bluetooth LE secure connection pairing. This foundation enables pairing using the Elliptic Curve Diffie-Hellman (ECDH) public key cryptography algorithm. The use of the ECDH keys provides much stronger security against passive eavesdropping and MIMT attacks. As a result, this feature enables higher level of security for connection authorization. The device includes Bluetooth 4.1 scatternet capabilities, allowing sensor network topology with concurrent LE sensor and peripheral roles. This feature allows LE simultaneous TX and RX, connecting up to 10 Bluetooth low energy or Bluetooth classic devices while consuming lower amounts of energy overall.
