l The capture session started after transmission of the vital information
l The analyzer incorrectly received a frame with the traversal information
l The communication monitored takes place between two players with implicit information not included in the
transmission
In any case, either view the RFCOMM payload of this frame (and other frames with the same channel) as hex data,
or assist the analyzer by selecting a protocol using this dialog.
Note that you may use the rest of the analyzer without addressing this dialog. Additional information gathered
during the capture session may help you decide how to respond to the request for decoding information.
If you are not sure of the payload carried by the subject frame, look at the raw data shown under data in the
Decode pane in the Frame Display. You may notice something that hints as to the profile in use.
In addition, look at some of the frames following the one in question. The data may not be recognizable to the
analyzer at the current point due to connection setup, but might be discovered later on in the capture.
3.2.4.3 RFCOMM Override Decode Information
The Set Subsequent Decoder Parameters dialog allows the user to override an existing parameter at any
frame in the capture where the parameter is used.
If you have a parameter in effect and wish to change that parameter:
1. Select the frame where the change should take effect, and
select Set Subsequent Decoder Parameters from the
Options menu, or by selecting a frame in the frame display
and choosing from the right-click pop-up menu, and make
the needed changes.
2. Change the RFCOMM parameter by selecting from the
Change the Selected Item to Carry drop down list.
3. If you wish to remove an overridden rule click on Remove
Override button. If you want to remove all decoder
parameter settings click on Remove All.
4. Choose the protocol the selected item carries from the
drop-down list, and click OK.
Each entry in the Set Subsequent Decoder Parameters dialog
takes effect from the specified frame onward or until redefined in
this dialog on a later frame.
