SIMPLELINK-CC26X2-SDK: Does BLE5-Stack support OOB authentication in Secure Connections pairing?

Part Number: SIMPLELINK-CC26X2-SDK

Hello,

BLE5-Stack's GAP Bond Manager seems to lack OOB authentication capability when Secure Connections pairing is used. BLE-Stack's GAP Bond Managers has parameters for it.

Is there a special reason for that? Do you have examples showing how to use OOB in Secure Connections pairing without GAP Bond Manager's support?

    Hi,

    Our BLE5 STACK currently does not support OOB authentication in SC and there is no examples available showing doing OOB in SC without gapbondmgr.

    Hi Christin,

    Any plan to support SC OOB pairing in the future BLE5-Stack release? This is critical to CC26X2 customers since CC26X2 has only BLE5-Stack and doesn't have BLE-Stack unlike CC26X0.

    Hi Christin,

    Just to clarify, does BLE5-Stack NOT support SC OOB pairing at all? In sm.h, there still is the fields for SC OOB pairing in smLinkSecurityReq_t:

    typedef struct
{
  uint8 ioCaps;                 //!< I/O Capabilities (ie.
  uint8 oobAvailable;           //!< True if remote Out-of-band key available
  uint8 oob[KEYLEN];            //!< Out-Of-Bounds key from remote device
  uint8 oobConfirm[KEYLEN];     //!< Out-Of-Bounds confirm from remote device. Secure Connections only.
  uint8 localOobAvailable;      //!< True if local Out-of-band key available. Secure Connections only.
  uint8 localOob[KEYLEN];       //!< Out-Of-Bounds local data. Secure Connections only.
  uint8 isSCOnlyMode;           //!< TRUE if Secure Connections Only Mode. Secure Connections only.
  smEccKeys_t eccKeys;          //!< Optionally specified ECC keys for pairing. Secure Connections only.
  uint8 authReq;                //!< Authentication Requirements
  keyDist_t keyDist;            //!< Key Distribution mask
  uint8 maxEncKeySize;          //!< Maximum Encryption Key size (7-16 bytes)
} smLinkSecurityReq_t;

    Is SC OOB pairing NOT supported by the Security Manager, or is the GAP Bond Manager NOT handling it? Please clarify.

    Hi,

    No, it does not support SC OOB at all unfortunately. The RnD did not delete that part of the code.

    Hi Christin,

    Does TI have plans to add back SC OOB feature to BLE5-Stack or provide some workaround?

    Hi,

    Yes, we will implement SC OOB feature to BLE5 CC26x2/CC13x2 STACK. We currently don't have the detail schedule yet, please come back in a month or 2.

    Thanks for your patience.
