Hsp driver

The audio driver can also retrieve the Bluetooth address of the paired HFP device. Each paired HFP device has a unique Bluetooth address, and this can be useful as a unique identifier string. To create and initialize an audio-specific filter factory context, the audio driver must store the HFP DeviceObject and the HFP FileObject in the filter factory context, and then initialize the IsConnected field to false. For many PortCls audio driver designs, there are two sub-devices registered for a given paired HFP device.

Each filter factory or, for PortCls audio drivers, each pair of filter factories represents the audio functionality of a single paired HFP device. Note that there is no specific maximum number of possible paired HFP devices, so the audio driver should avoid hard coding specific limitations.

As a practical matter, however, a PortCls driver must specify a maximum number of sub-devices when it calls PcAddAdapterDevice. PcAddAdapterDevice pre-allocates extra memory for each potential sub-device. The audio driver developer should select a number high enough to accommodate many paired devices, but at the same time select a number that doesn't result in a waste of resources.

For example, supporting only 2 HFP devices might be inadequate, and supporting would certainly result in overextended resources. Choose the best match for your PC and operating system.
