GattSession.MaxPduSizeChanged Event

Definition

Namespace:

Windows.Devices.Bluetooth.GenericAttributeProfile

An event that is raised when the maximum protocol data unit (PDU) size changes. The PDU is also known as the maximum transmission unit (MTU).

MaxPduSizeChanged is raised whenever the negotiated MTU for the Attribute Protocol (ATT) is changed. And that can be changed or negotiated by a remote Bluetooth peripheral. As a developer, you can't change the value used by Windows itself, since that's fully managed by the operating system.

Also see the GattSession.MaxPduSize property which, as mentioned, is read-only.
