[since 5.7] enum class QBluetooth::AttAccessConstraintflags QBluetooth::AttAccessConstraints

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

Constant	Value	Description
QBluetooth::AttAccessConstraint::AttAuthorizationRequired	0x1	The client needs authorization from the ATT server to access the attribute.
QBluetooth::AttAccessConstraint::AttAuthenticationRequired	0x2	The client needs to be authenticated to access the attribute.
QBluetooth::AttAccessConstraint::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.

[since 5.4] QLowEnergyHandle

Typedef for Bluetooth Low Energy ATT attribute handles.

This typedef was introduced in Qt 5.4.

enum class QBluetooth::Securityflags QBluetooth::SecurityFlags

This enum describe the security requirements of a Bluetooth service.

Constant	Value	Description
QBluetooth::Security::NoSecurity	0x00	The service does not require any security.
QBluetooth::Security::Authorization	0x01	The service requires authorization by the user, unless the device is Authorized-Paired.
QBluetooth::Security::Authentication	0x02	The service requires authentication. Device must be paired, and the user is prompted on connection unless the device is Authorized-Paired.
QBluetooth::Security::Encryption	0x04	The service requires the communication link to be encrypted. This requires the device to be paired.
QBluetooth::Security::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.
