The attached PDF file contains two A3 format "posters".

The first one summarize the contents of the SMP Pairing Request and SMP Pairing Response packets (BLE 4.2). It shows how are the sub-fields of these packets set and what do they represent.

The second one contains a diagram which summarizes how the pairing method and it's properties are determined during the SMP Pairing procedure for both BLE Legacy Pairing (BLE4.0 and BLE 4.1) and BLE Secure Connections Pairing with ECDH (BLE 4.2). Some of the tables in the diagram are taken from the BLE Specification.
