Subject: [PATCH] BLE: [IOT] Initiate disconnection when encryption fails
|
||
|
during pairing
|
||
|
|
||
|
Usecase:
|
||
|
1. Keep remote device (IOGEAR Keyboard) in advertising mode.
|
||
|
2. Pair and connect remote device with DUT.
|
||
|
3. Disconnect remote from settings menu.
|
||
|
4. Keep remote back in pairing mode. (This deletes link key
|
||
|
at remote side.)
|
||
|
5. Select remote for connection from Settings menu from
|
||
|
paired devices.
|
||
|
|
||
|
Issue:
|
||
|
Device is seen stuck in "Connecting state" in settings app.
|
||
|
|
||
|
Root Cause:
|
||
|
When pairing is initiated again from DUT (step 5), encryption
|
||
|
change event is received with status "PIN or Key Missing" after
|
||
|
connection complete but disconnection is not initiated by DUT
|
||
|
thereafter.
|
||
|
|
||
|
Fix:
|
||
|
Trigger disconnection if encyption fails with reason like
|
||
|
HCI_ERR_AUTH_FAILURE, HCI_ERR_KEY_MISSING,
|
||
|
HCI_ERR_ENCRY_MODE_NOT_ACCEPTABLE etc
|
||
|
|
||
|
