Yes, the summary fits my view. Still your comment "Bluetooth_SIG specification has take care of security inherently" indicates that you are taking too many assumptions about how real world attacks and securing embedded devices work, kind of foggy cloud named "security" (someone will put a stamp on it and voila it's solved;)... but maybe I'm totally wrong. Good luck!
