Security Mode can be set to either No
Security or Link level security.
If a device has selected link level security, no
remote device can connect to it without
bonding (see “Bonding”
). Furthermore, only
when you have selected link level security can
you use encryption (see below).
Encryption Mode can be enabled or
disabled. Based on the use of a link key, this
feature can only be enabled when link level
security has been selected (see above).
If encryption is enabled: When your device is
communicating, only the linked devices will be
able to understand the data sent between
them.
Connectability Mode refers to whether or not
remote devices having discovered your device
will be allowed to establish a link to it. In other
words, selecting non-connectable mode is a
way of ensuring that no remote device can
connect to your device.
Discoverability Mode refers to whether or
not other devices will be allowed to discover
your device. In other words, selecting non-
discoverable mode is a way of preventing
remote devices from discovering your device.
The default settings are as shown in the examples
(the illustrations) above.
Note: If devices wanting to communicate have
different security settings, the highest level of
security required will be used. Imagine, for
instance, that a device requiring no security tries
to establish a link to a device requiring link level
security. Link establishment between the two
devices will then require link level security (i.e.
the devices will have to bond, both entering a
pass key).
