Hi,
When using LE secure - what exactly is exchanged via OOB channel? Is it all the procedure until LTK generation?
Thanks!

Hi Roei,
Please have a look at section 2.3.5.6.4 in Bluetooth Spec Vol 3 Part H v5.2

So the information exchanged is A, ra, Ca and B, rb, Cb on the other side.
These are the information to avoid MITM. After this confirmation at step 5a/b the LTK will be generated on each side.
