Hi Arun,

Can you be more specific as to which algorithm you are referring to? Overall, we follow the Bluetooth 5.1 specification.

Thanks,
Jacob

Hi Jacob,

I am referring about the encryption algorithm which is using in this device on data confidentiality . for example: AES, Elliptic curve, etc

Hi Arun,

The encryption algorithms are all implemented in the Bluetopia stack in the Generic Access Profile. The CC2564B (Bluetooth 4.0) supports AES encryption for a Low Energy connection. You can check this encryption with the GAP_Query_Encryption_Mode API. You may also want to review the demos in the 4.0 stack to see how encryption can be used.

You can also refer to this thread for more information.

TI recommends the CC2564C (Bluetooth 5.1 compliant) instead which offers ECDH public key cryptography for BLE secure pairing.

Best,
Jacob
