During advertisement, the adv packet data may contain device name, tx power level, service UUID values, …… we can dynamically change the adv packet data during advertisement, this won't effect on bonding. If we made any changes in the BLE device address or in device security tab and trying to connect then the pairing process will takes place again.
Pairing is the process to enable security features. In this process, two devices are authenticated, the link is encrypted and then the encryption keys are exchanged. Whereas bonding is the process in which the security keys and identify information are saved. These security keys are calculated based on device address, pairing parameters.
