Discovery
Auto Discoverable/Pair/Connect
When this is selected (the default), the APx Bluetooth
Option is discoverable by remote Bluetooth devices. If
the remote device initiates pairing, the APx will pair. If
the remote device initiates connection, the APx is
available to connect for the profiles checked here.
Not Discoverable, No Pair/Connect
When this is selected, the APx Bluetooth Option is not
discoverable by remote devices, and it will not
respond to pairing or connection initiated by remote
device.
SSP Mode
APx provides four SSP (Secure Simple Pairing) options.
The Just Works choice is used in Bluetooth device
relationships that require little security. The Numeric
Comparison choices are man-in-the-middle (MITM)
interactions for device relationships that require
higher security. Choose the SSP Mode that is appropri-
ate for the Bluetooth device you are testing. See More
About Secure Simple Pairing on page 142 for detailed
information.
