BLE - passkey

[Roei]

Hi,

I have a question regarding BLE connection with passkey.

When starting connection and bonding process, a device can display a passkey so the other side will send this passkey in order to establish connection.

My question is - what's happening in the background while waiting for this passkey to be sent? Does other procedures (diffie-hellman etc) are freeze until passkey is sent?

Do you have any flow chart which can explain the steps?

Thanks!

• Central Security procedures
• Peripheral Security procedures

Thanks!

Regarding "Bonding: Passkey Entry, Peripheral Displays" - where can I see the stage when the user send the passkey to the peripheral?

And regarding "Bonding: Out of Band" - does 'OOB communication' grey line refers to all other line under it? So everything after this line happens in out of band?
