CC2745R10-Q1: Configuration Impact on Connection: Passkey Entry vs. OOB

Part Number: CC2745R10-Q1

Hi Team,
I have a few technical questions regarding the pairing method configuration on the TI CC2745 platform. Thank you in advance for your support.
  1. Regarding GAPBondMgr_SetParameter(GAPBOND_OOB_ENABLED, ...):
    Does calling this API force the device to use the OOB pairing flow for every​ subsequent connection? How can we configure the stack to trigger the OOB pairing flow only when needed (on-demand)?
  2. Difference between APIs:
    What is the difference and relationship between setting GAPBOND_OOB_ENABLEDvia GAPBondMgr_SetParameter()and using GAPBondMgr_SCSetRemoteOOBParameters()? How do these two APIs work together?
Current Requirement:
We need to support both CCC​ (Car Connectivity Consortium) and ICCE​ (Integrated Car Connectivity Ecosystem) digital key protocols simultaneously:
  • CCC​ requires Out-of-Band (OOB)​ pairing.
  • ICCE​ requires Passkey Entry.
Could you please advise on the recommended configuration strategy to support both pairing methods on the same device?
 
Best regards.

    One more question: Can I configure the pairing method on a per-connection basis (e.g., setting OOB for one connection and Passkey Entry for another)?

    Hi Leo,
    1. Have you tried default OOB off, and only enable it when you find CCC in connection,  and after successful pairing turn it off again? 
    2. GAPBondMgr_SetParameter will only set the overall enable/disable of OOB, while GAPBondMgr_SetParameter not only sets the OOB EN/DIS it also both OOB data(rand, confirm) and the name suggests it used in SC pairing.

    We find your suggestion feasible and will proceed with testing. Please note that this may introduce certain constraints to the customer pairing flow.
