blinking.
Step 5 Establish connection between the Bluetooth devices under analysis.
Step 6
When BTTracer senses Piconet traffic, the Green Sync light goes
ON solid, recording starts and the status bar in the bottom of the
analyzer screen shows activity.
Recording may be stopped manually or when the recording buffer is filled.
Note After the Sync light starts blinking, a connection between the Bluetooth
devices should be established within one (1) minute.
Passive Sync & Record
Passive Sync and Record is used in situations where the Master device and
slave devices do not support Inquiry Scan mode. When selected, BTTracer
enters Inquiry Scan and Page Scan mode and waits for a page from the
Master device. When the piconet Master pages BTTracer, BTTracer
obtains the information necessary for synchronization and then attempts to
synchronize to the piconet controlled by that Master.
"Passive Sync and Record" is designed to be used with established piconets
or private device networks.
Running "Passive Sync and Record" with Established Piconets
For most situations, "Passive Sync and Record" will be run after a piconet
has been established. The steps are as follows:
Step 1
Establish a connection between two or more Bluetooth devices.
Step 2
Under General Recording Options, select "Passive Sync & Record."
Step 3 Under the Modes tab in Recording Options, enter the address for the
piconet’s master device.
Step 4
Make up an address for BTTracer and enter it into the Page Target
address in the Modes tab in Recording Options. Make sure you do
not select an address for any other local device.
Step 5 Press the record button on the toolbar in
BTTracer to start a recording session.
Step 6
If necessary, have Master "discover" BTTracer through a General
Inquiry.
Step 7
From the Master device, initiate a page to BTTracer’s address. This
action will enable BTTracer to synchronize to the piconet. However,
the analyzer will not complete the page sequence from the Master.
This will cause the Master to time out in this request.
