CC2564C: Secure Connections Only Mode

Pierre BOGRAND

Part Number: CC2564C

Hi,

Does the CC2564C controller supports the Secure Connections Only Mode, as defined in the Bluetooth Core Specification (use of P-256 elliptic curve for pairing and AES-CCM for encryption), for BR/EDR mode (Bluetooth Classic) and/or for BLE mode (Bluetooth Low Energy) ?

If it does, might it impact its capacities (mainly bandwith and data rate) if used ?

Thank you in advance for your answer.

Regards,

Pierre

    Hi Pierre,

    The Secure Connections Only mode relies on the host stack supporting that feature - the CC2564C does work with secure connections only enabled, but it is the stack's responsibility to enable that feature.

    For the TI Bluetopia stack, please take a look at the GAP_LE_SC_Only_Mode() function in GAPAPI.h. That API will allow you to set the CC2564C into Secure Connections Only mode.

    In terms of capacities, there shouldn't be any impact beyond the usual SC impact, as all that mode is doing is forcing connections to use the secure connections feature.

    Let me know if you need more clarification or have further questions on secure connections on the CC2564C.

    Regards,

    Michael

    Hi Michael, 

    Thank you for your answer. I am using BlueZ instead of Bluetopia for my host Bluetooth stack, but I'll check its specification concerning SC mode.
