Detailed Description#

An object of this class provides a descriptor to be added to a QLowEnergyCharacteristicData object via addDescriptor() .

Note

The member functions related to access permissions are only applicable to those types of descriptors for which the Bluetooth specification does not prescribe if and how their values can be accessed.

__init__(uuid, value)#

Parameters:

uuid – QBluetoothUuid
value – QByteArray

Creates a new object of this class with UUID and value being provided by uuid and value, respectively.

__init__(other)

Parameters:: other – QLowEnergyDescriptorData

Constructs a new object of this class that is a copy of other.

__init__()

Creates a new invalid object of this class.

isReadable()#

Return type:: bool

Returns true if the value of this descriptor is readable and false otherwise.

isValid()#

Return type:: bool

Returns true if and only if this object has a non-null UUID.

isWritable()#

Return type:: bool

Returns true if the value of this descriptor is writable and false otherwise.

__ne__(b)#

Parameters:: b – QLowEnergyDescriptorData
Return type:: bool

Returns true if a and b are unequal with respect to their public state, otherwise returns false.

__eq__(b)#

Parameters:: b – QLowEnergyDescriptorData
Return type:: bool

Returns true if a and b are equal with respect to their public state, otherwise returns false.

readConstraints()#

Return type:: Combination of AttAccessConstraint

Returns the constraints under which the value of this descriptor can be read. This value is only relevant if isReadable() returns true.

setReadPermissions(readable[, constraints=QBluetooth.AttAccessConstraints()])#

Parameters:

readable – bool
constraints – Combination of AttAccessConstraint

Specifies whether the value of this descriptor is readable and if so, under which constraints.

setWritePermissions()

setUuid(uuid)#

Parameters:: uuid – QBluetoothUuid

Sets the UUID of this descriptor to uuid.

See also

uuid()

setValue(value)#

Parameters:: value – QByteArray

Sets the value of this descriptor to value. It will be sent to a peer device exactly the way it is provided here, so callers need to take care of things such as endianness.

value()

setWritePermissions(writable[, constraints=QBluetooth.AttAccessConstraints()])#

Parameters:

writable – bool
constraints – Combination of AttAccessConstraint

Specifies whether the value of this descriptor is writable and if so, under which constraints.

setReadPermissions()

swap(other)#

Parameters:: other – QLowEnergyDescriptorData

Swaps this object with other.

uuid()#

Return type:: QBluetoothUuid

Returns the UUID of this descriptor.

See also

setUuid()

value()#

Return type:: QByteArray

Returns the value of this descriptor.

See also

setValue()

writeConstraints()#

Return type:: Combination of AttAccessConstraint

Returns the constraints under which the value of this descriptor can be written. This value is only relevant if isWritable() returns true.
