Re-applying Encryption On Incomplete Traces
If your trace does not capture the authentication procedure, there will be no
way for the analyzer to determine the BD Address of the Slave device.
Accordingly, the software will not be able to decrypt the trace file.
If you are using a development kit and already know the BD Address of the
Slave device and the Link Key, you can enter it manually in the Save As
dialog box shown above.
Note LMP_start_encryption_req still has to be present in the trace in order to manually
correct the settings.
Step 1 Select File > Re-apply Encryption Settings.
The Save As dialog opens (shown on preceding page.)
Step 2 Select the LT Address for the device whose traffic you are
trying to decrypt.
Step 3 Click the Edit button.
Step 4 The Set Encryption Options dialog box opens.
Step 5 Enter the BD Address and Link Key.
Step 6 Click OK.
The dialog box closes.
Step 7 Click Save.
The dialog box closes and the traffic is decrypted according to your settings.
