• Sync to piconet using fake connection response:
This mode can only be used during the connect
phase, i.e. when the piconet master connects to a
new slave. The Protocol Analyser pretends it is the
slave unit chosen in the Select ... dialog box and
obtains the master clock information by initiating a
new connection as if it were that slave. Immediately
after the clock information has been retrieved, the
Protocol Analyser stops transmitting, and the piconet
master continues the connection attempt with the
true slave.
• Sync to piconet using slave inquiry: This mode can
only be used during the connect phase and is based
on the same principle as the method mentioned
above in connection with Sync to piconet using fake
connection response. Instead of pretending to be the
slave unit chosen in the Select ... dialog box, the
Protocol Analyser listens for the clock information
sent in the connect phase to the new piconet slave
and therefore does not interfere with the piconet in
any way. To be able to catch the clock information
on the right frequency, it is necessary to obtain the
slave clock. This is done by performing an inquiry to
the slave.
To select master or slave, click Select. The following dialog
box opens:
The Bluetooth Protocol Analyser will now carry out device
discovery, and then display a list of all active Bluetooth devices
within range. To select the master or slave you want to
connect to, highlight the desired device in the above dialog box
and click Select.
You can edit the MAC address in the edit field, thus changing
to a different address.
