1. You can manually select Select the Bluetooth
device address (BD_ADDR) form the
Classic
Device:
drop down list or from the Device
Database . You can also type in the address as a
12 digit hex number (6 octets). The "0x" is
automatically typed in by the control. Any
devices entered this way is added to the
Device Database.
2. Specify the "BD_ADDR for the LE Device" by selecting "Sync
with Classic Devices Only". By doing this, the low energy
device will follow connections from or to the specified
device, or from or to the first Classic device that connects
over LE.
Classic Encryption
Bluetooth devices can have their data encrypted when they communicate. Bluetooth devices on an encrypted
link share a common link key in order to exchange
encrypted data. How that link key is created
depends upon the pairing method used.
There are three
encryption options in
the I/O Settings dialog.
a.
PIN Code
(ASCII)
b. PIN Code (Hex)
c.
Link Key
l
The first and second options use a PIN Code to
generate the Link Key. The devices generate link Keys during the Pairing Process based on a PIN Code. The
second Link Key generated from this process is also based on a random number so the security cannot be
compromised. If the analyzer is given the PIN Code it can determine the Link Key using the same
algorithm. Since the analyzer also needs the random number, the analyzer must catch the entire Pairing
Process or else it cannot generate the Link Key and decode the data.
Example:
If the ASCII character PIN Code is ABC and you choose to enter the ASCII characters, then select PIN
Code (ASCII) from the Encryption drop down list and enter ABC in the field below.
If you choose to enter the Hex equivalent of the ASCII character PIN Code ABC, then select
PIN Code
(Hex)
from the Encryption drop down list and enter 0x414243 in the field. Where 41 is the Hex
equivalent of the letter A, 42 is the Hex equivalent of the letter B, and 43 is the Hex equivalent of the
letter C.
Note: When PIN Code (Hex) is selected from the Encryption drop down list, the 0x
prefix is entered automatically.
