The QBluetooth namespace provides classes and functions related to Bluetooth.

This enum describes the possible requirements for reading or writing an ATT attribute.

Constant	Value	Description
`QBluetooth::AttAuthorizationRequired`	`0x1`	The client needs authorization from the ATT server to access the attribute.
`QBluetooth::AttAuthenticationRequired`	`0x2`	The client needs to be authenticated to access the attribute.
`QBluetooth::AttEncryptionRequired`	`0x4`	The attribute can only be accessed if the connection is encrypted.

This enum was introduced or modified in Qt 5.7.

The AttAccessConstraints type is a typedef for QFlags<AttAccessConstraint>. It stores an OR combination of AttAccessConstraint values.

Typedef for Bluetooth Low Energy ATT attribute handles.

This typedef was introduced in Qt 5.4.

This enum describe the security requirements of a Bluetooth service.

Constant	Value	Description
`QBluetooth::NoSecurity`	`0x00`	The service does not require any security.
`QBluetooth::Authorization`	`0x01`	The service requires authorization by the user, unless the device is Authorized-Paired.
`QBluetooth::Authentication`	`0x02`	The service requires authentication. Device must be paired, and the user is prompted on connection unless the device is Authorized-Paired.
`QBluetooth::Encryption`	`0x04`	The service requires the communication link to be encrypted. This requires the device to be paired.
`QBluetooth::Secure`	`0x08`	The service requires the communication link to be secure. Simple Pairing from Bluetooth 2.1 or greater is required. Legacy pairing is not permitted.

The SecurityFlags type is a typedef for QFlags<Security>. It stores an OR combination of Security values.
