Delete BLE connection bonding keys with pc-ble-driver-py

[Arto Tanskanen]

Is it possible to manually delete/inject bonding keys when BLE connecting to device with using Nrf52 and pc-ble-driver.py? I would need to execute following scenario:

1. BLE connection to device

2. store bonding keys

3. reset bonding keys

4. re-connect multiple times with new keys

Try between each round if original bonding keys still works

Hi,

pc-ble-driver-py gives access to the SoftDevice API through serialization, where the PC application has the role of the "application chip", the nRF device directly connected to the PC is the "connectivity chip", and the BLE connection is to a device under test. It does let you implement what you describe, yes.

Please note that all key handling must be done by the pc-ble-driver-py application, as the SoftDevice does not store bonding information internally. You can reference the message sequence charts from the SoftDevice documentation, e.g. Bonding: Just Works, Encryption Establishment using stored keys, etc.

Hi,

Did you succeed in implementing the bond handling?
