About LESC security anomaly detection on smartphones
SDK: 15.3.0
Example: ble_app_multirole_lesc
DeviceA: EYSHJNZWZ (nRF52832)
DeviceB: Smartphone (Android)
Please tell me about the operation when LESC security is abnormal.
(1) Connect DeviceA and DeviceB
(2) Bonding with DeviceA and DeviceB with LESC security
(3) Disconnect DeviceA and DeviceB
(4) Delete the key bonded with DeviceA.
(5) Reconnect DeviceA and DeviceB
(6) Attempt to establish LESC security with DeviceA and DeviceB
(7) DeviceA has a key and DeviceB has no key, so a security error occurs.
(8) DeviceA can receive security abnormalities in events
(9) DeviceB cannot receive security errors in events
There is a problem that DeviceB cannot receive the security error in the event as described above.
Is it possible to send an authentication NG notification or re-encryption request from DeviceA to DeviceB in the event of a security error?
The purpose is to know that a security error has occurred in DeviceB.
For reference, it seems that the above-mentioned correspondence is possible with the device of Silicon Labs.
