Manage Security Modes
This command controls the security access mode and device pairing.
Themodesavailableare:
L0 Disable encryption, authentication and exclusion
L1 Enable authentication
L2 Enable encryption and a uthentication
L3 Enable encryption, a uthentication a nd exclusive
Mode L0 allows any remote device to connect.
Mode L1 require the remote device to be authenticated by a PIN request.
The PIN code for the module is set to a user-specified value with the S4
command. Currently the default PIN is the NULL string (see Note).
Mode L2 adds encryption to the Bluetooth link.
Mode L3 adds exclusive connection to one specific Bluetooth device.
In this mode only connection requests from the initial device are al-
lowed. Connections from other d evices are rejected even if they supply
the correct PIN code.
Device pairing a nd bonding are associated with this command and works
as follows:
After a n L command is executed the current device pairing and bonding is
deleted. The next device to connect becomes paired and bonded to the
module.
In Modes L1 and L2, other devices are allowed to connect but only the
first d evice to connect is paired and bonded. Other devices are always re-
quired to supply a PIN code to complete the connection.
In Mode L3, only one device is allowed to connect. This device is paired
and bonded and needs to supply the PIN code only on the initial connec-
tion.
Example: “L3<CR>“
Note: Some of the Bluetooth user interfaces cannot supply a NULL string
as a PIN code. Use the S4 command to specify a PIN code that is not
NULL.
