QLowEnergyDescriptorData#

The QLowEnergyDescriptorData class is used to create GATT service data. More

Synopsis#

Functions#

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.

class PySide6.QtBluetooth.QLowEnergyDescriptorData#

PySide6.QtBluetooth.QLowEnergyDescriptorData(uuid, value)

PySide6.QtBluetooth.QLowEnergyDescriptorData(other)

Parameters

Creates a new invalid object of this class.

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

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

PySide6.QtBluetooth.QLowEnergyDescriptorData.isReadable()#
Return type

bool

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

PySide6.QtBluetooth.QLowEnergyDescriptorData.isValid()#
Return type

bool

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

PySide6.QtBluetooth.QLowEnergyDescriptorData.isWritable()#
Return type

bool

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

PySide6.QtBluetooth.QLowEnergyDescriptorData.__ne__(b)#
Parameters

bPySide6.QtBluetooth.QLowEnergyDescriptorData

Return type

bool

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

PySide6.QtBluetooth.QLowEnergyDescriptorData.__eq__(b)#
Parameters

bPySide6.QtBluetooth.QLowEnergyDescriptorData

Return type

bool

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

PySide6.QtBluetooth.QLowEnergyDescriptorData.readConstraints()#
Return type

AttAccessConstraints

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

PySide6.QtBluetooth.QLowEnergyDescriptorData.setReadPermissions(readable[, constraints=QBluetooth.AttAccessConstraints()])#
Parameters
  • readable – bool

  • constraintsAttAccessConstraints

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

PySide6.QtBluetooth.QLowEnergyDescriptorData.setUuid(uuid)#
Parameters

uuidPySide6.QtBluetooth.QBluetoothUuid

Sets the UUID of this descriptor to uuid.

uuid()

PySide6.QtBluetooth.QLowEnergyDescriptorData.setValue(value)#
Parameters

valuePySide6.QtCore.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()

PySide6.QtBluetooth.QLowEnergyDescriptorData.setWritePermissions(writable[, constraints=QBluetooth.AttAccessConstraints()])#
Parameters
  • writable – bool

  • constraintsAttAccessConstraints

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

PySide6.QtBluetooth.QLowEnergyDescriptorData.swap(other)#
Parameters

otherPySide6.QtBluetooth.QLowEnergyDescriptorData

Swaps this object with other.

PySide6.QtBluetooth.QLowEnergyDescriptorData.uuid()#
Return type

PySide6.QtBluetooth.QBluetoothUuid

Returns the UUID of this descriptor.

setUuid()

PySide6.QtBluetooth.QLowEnergyDescriptorData.value()#
Return type

PySide6.QtCore.QByteArray

Returns the value of this descriptor.

See also

setValue()

PySide6.QtBluetooth.QLowEnergyDescriptorData.writeConstraints()#
Return type

AttAccessConstraints

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