The information in this section and its subtopics provides guidelines and sample codes for power control handling by such bus drivers and explains the interaction with the Bluetooth core drivers. enabling the Bluetooth radio and as a sleep/wake signaling). GPIOs, can be used as a 'sideband' mechanism for handling power control (e.g.

In addition, simpler and low power controllers, e.g. UART (Universal Asynchronous Receiver/Transmitter). The extensibility model DDI will remain unchanged in Windows to give a system integrator the flexibility to choose a suitable transport for SoC platforms, e.g. USB transport and the extensible transport models will continue to be supported in the Windows 8.1. Windows 8 introduced the Bluetooth Extensible Transport IOCTLs. Prior versions of Windows, up to Windows 7, provided an inbox class driver for Bluetooth with USB as the only transport option. The information in this section and its subtopics applies to:Īs a short range wireless radio, Bluetooth is often a function within a multifunction controller that is integrated on a System on Chip (SoC) system. The information in this section and its subtopics supplements the bus sample driver by providing guidelines and sample codes for handling power controls. However, an out-of-band control other than using its own IO transport (UART in the case of the WDK sample) is often used to support idle and wake controls such a mechanism is required and used to optimize power consumption. The sample illustrates how to handle IOCTL (IO Control) requests from its upper layer and how to deliver HCI packets to its serial controller driver at its lower layer. The Bluetooth Serial HCI Bus Driver sample can help IHVs facilitate the development of the their transport bus driver. IHVs need to implement a transport bus driver in order to support Bluetooth functionality of a multifunction controller often integrated in a System on Chip (SoC) system.
