Hi LJ Ye
Pairing is to exchange the keys. Bonding store the keys/peer_addr to the nvram.
Not suggest to delete the bonding info as if the peer side still store the bonding data, the next time connection will failed.
Per my understand, auto connect is depend on application's function. App or firmware need to implement. Bonding only store the keys/peer_addr. If connection has happened, no need to do the pair progress(like input fixed pair key) for people, the key exchange can be handled by stack auto.
