No, not close, just mark it so people with the same problem as your initial question can see from the threads overview that there is a solution to it. I just mentioned it because a lot of people forget to mark this :) It's up to you if you feel wether or not the answer solved your issue.

Good point.

Did you mean 'close'?

I am still implementing my bonding manager and so based on the outcome of testing I may have feedback that could help others.

You are a star !!

Now that you point me to it I can see it in the documentation. Hopefully Nordic update the message sequence chart with a note to make it clear.

It does however mean that one needs to keep some static memory around for those values to be populated given the key exchange will occur much later. Can understand why it is done the way it is as the local keys have to be provided prior to phase 3.

Regardless, you have saved me a lot of time waiting from an official response.

Many thanks Mahendra

For the S120, supply a pointer to a key set structure when calling sd_ble_gap_sec_params_reply. When the key exchange phase is finished and the AUTH_STATUS event comes, the key set structure has been populated with the exchanged keys, if any.
