    Hi , I 've read 3 books is Getting Started With Bluetooth Low Energy, Inside Bluetooth Low Energy and Corev5 , so I know answer for my question but I want to ask to make sure I do not misunderstand . But , have a problem I really do not understand is : In pairing /bonding , LL connection will be encrypted then PDUs in Link Layer will be encrypted. So if do not pairing /bonding , LL connection won't be encrypted ? And only PDUs in Link Layer encrypted . Thank
