Type Documentation
enum QBluetooth::AttAccessConstraint
flags QBluetooth::AttAccessConstraints
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 QLowEnergyHandle
Typedef for Bluetooth Low Energy ATT attribute handles.
This typedef was introduced in Qt 5.4.
enum QBluetooth::Security
flags QBluetooth::SecurityFlags
This enum describe the security requirements of a Bluetooth service.

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. |
