Hi Christin, is there any conclusion to this issue?

Hi Christin, I tested it with SDK4.10, SDK4.40 and SDK5.40, the SDK4.10 and the SDK4.40 have this problem, but the SDK5.40 does not.

Please check the latest sniffer log.

Hi Shepherd,

I checked the log, TI device did send out security request to iPhone.

In this case, the central device(iPhone) should respond with with starting encryption if the LTK is saved and valid from previous pairing.

I am not sure why iPhone does not start the encryption.

can you prepare snifferlog with

• iOS 16 and CC2642 with 4.40 SDK first time pairing just work
• iOS 16 and CC2642 with 4.40 SDK reconnect using just work
• iOS 16 and CC2642 with 5.40 SDK first time pairing just work
• iOS 16 and CC2642 with 5.40 SDK reconnect using just work

Hi Christin,

The latest attachment (ios16-full.zip) contains:

• iOS 16 and CC2642 with 4.10 SDK first time pairing just work
• iOS 16 and CC2642 with 4.10 SDK reconnect using just work

The first attachment (IOS16.zip) contains:

• iOS 16 and CC2642 with 4.40 SDK first time pairing just work
• iOS 16 and CC2642 with 4.40 SDK reconnect using just work

I found pairing successful but bonding failed in IOS16.zip(IOS16 and cc2642 with 4.40 SDK).

Both pairing and bonding were successful in ios16-full.zip(iOS 16 and CC2642 with 4.10 SDK).
