I was wondering whether bonding between devices is possible without using a passkey.
I found a good documentation by Nordic Semi which illustrates all the bonding , pairing process in Message Sequence Charts.
By analysing them I concluded that Bonding between my nRF51822 peripheral can be done with the master iPhone without asking for a passkey. (Using just works)
Am I right with my findings (Is it possible to bond without key) ?
What all things I have to take care? What are the demerits when I am using this (Security Issues)? It has mentioned about storing peripheral keys, What exactly these keys contain? (If this is not possible: Is there a way to implement this, like by storing same passkey in both devices)
Please correct me wherever I found it wrong..
