Set Local Encryption Mode (SetLocalEncryptionMode, 0x4E)

With this command, the encryption of the Bluetooth
tivated or deactivated. This setting can be done independently of the device
role, but only affects the master. If encryption is activated, devices that do not
use encryption cannot connect.
Note
Encryption can be activated without activating an authentication. The actual en-
cryption of the data takes place after an authentication.
The security of the encryption is linked to the quality of the password.
Connections between devices can only be established if the settings for encryp-
tion, authentication and password are synchronized. This can be achieved by hav-
ing identical settings for the devices to be connected.
