Profile drivers primarily use IOCTL_INTERNAL_BTH_SUBMIT_BRB to communicate and interact with the functionality provided in the Bluetooth driver stack.

#TOSHIBA BLUETOOTH STACK BLUETOOTH NOT READY HOW TO#

The Bluetooth driver stack supports the following IOCTLs and BRBs kernel-mode callers (generally for driver-to-driver communication) through IRP_MJ_INTERNAL_DEVICE_CONTROL:įor more information about how to use the IOCTLs described in the previous lists, see Bluetooth IOCTLs. The Bluetooth driver stack supports the following IOCTLs for kernel-mode callers through IRP_MJ_DEVICE_CONTROL: The profile driver specifies one of the I/O control codes in the following list in the IRP.

Profile drivers then communicate with their devices by using IOCTL requests that are delivered to the device by means of an IRP_MJ_INTERNAL_DEVICE_CONTROL or IRP_MJ_DEVICE_CONTROL IRP. A profile driver communicates with its device by allocating and sending IRPs down the Bluetooth driver stack to the Bluetooth port driver, Bthport.sys.Ī profile driver allocates and initializes IRPs to be processed by Bthport.sys. Profile drivers communicate with the Bluetooth driver stack through the standard I/O Request Packet (IRP)-based mechanism employed by all drivers based on the WDM architecture. The profile driver to be loaded is selected based on the INF file that installs the profile driver and the device identifier, as generated by the Bluetooth driver stack and described in Installing a Bluetooth Device. Next, the driver stack uses standard Plug and Play (PnP) mechanisms to load the appropriate profile driver for each device. The driver stack then generates device identifiers (device IDs) for all paired devices. After Windows loads and initializes the Bluetooth driver stack, the driver stack discovers active Bluetooth devices that have already been paired.
