1.9.4. Security Mode
The factory set security mode is 3 (Highest). This field has 3 available settings from the drop down list:
1) Selecting option “1” will immediately place your adapter into security mode 1. This is the lowest security mode that the
Adapter can be configured to. Connections, including service discovery, can take place without the need for “pairing” or
“bonding”. In mode 1, the Adapter automatically accepts all access requests without initiating authentication, encryption, or
authorization procedures. Any attempt by a remote application to perform authentication or encryption procedures will be
rejected.
2) Selecting option “2” will immediately place your Adapter into security mode 2. This mode allows remote Bluetooth devices
to search for and retrieve the services on your Adapter without pairing, but will not allow them to connect unless the 2
devices are paired.
3) Selecting option “3” will immediately place your Adapter into security mode 3 (default). This is the highest security mode
available. Connections of any kind (other than a device discovery) from a remote Bluetooth device are only allowed after a
successful “pairing” has been performed. No services will be shown to other Bluetooth devices unless the 2 devices are
successfully paired.
The tables below show some more information with regards to the application of the security settings…

1.9.5. Encryption
Encryption is a method of ensuring that the communications between 2 devices cannot be “bugged” or “listened” to by any
unauthorised source. This encryption is performed in lower layers of the protocol stack as defined by the Bluetooth
Specification.
The factory set Encryption mode is “Disabled”. This field has a drop down list from which the configuration can be changed
to enable “Point to Point” or “Point to Point & Broadcast”.
