HCI IOCTL Functions
The following table shows all the host controller interface (HCI) IOCTLs.
| HCI IOCTL | Description |
|---|---|
| BTH_HCI_IOCTL_GET_BD_FOR_HANDLE | Retrieves the address of a peer Bluetooth-based device for connection handle. |
| BTH_HCI_IOCTL_GET_HANDLE_FOR_BD | Retrieves the connection handle for a Bluetooth device if it is connected. |
| BTH_HCI_IOCTL_GET_NUM_UNSENT | Retrieves the number of packets pending before being sent to the card. |
| BTH_HCI_IOCTL_GET_NUM_ONDEVICE | Retrieves the number of unconfirmed packets sent to the hardware. |
| BTH_HCI_IOCTL_GET_NUM_PENDING | Retrieves the number of confirmed and pending packets that are in execution on the hardware. |
| BTH_HCI_IOCTL_GET_INQUIRY | Retrieves the inquiry status. |
| BTH_HCI_IOCTL_GET_PERIODIC_INQUIRY | Retrieves periodic inquiry status. |
| BTH_HCI_IOCTL_GET_LOOPBACK | Retrieves the loopback status. |
| BTH_HCI_IOCTL_GET_ERRORS | Retrieves the number of hardware errors. |
| BTH_HCI_IOCTL_GET_FLOW | Retrieves host flow control status. |
| BTH_HCI_IOCTL_GET_COMMANDSIZE | Retrieves the loopback status. |
| BTH_HCI_IOCTL_HANDLE_AUTHENTICATED | Retrieves the authentication status of the connection. |
| BTH_HCI_IOCTL_HANDLE_ENCRYPTED | Retrieves encryption status of the connection. |
| BTH_HCI_IOCTL_GET_UNDER_TEST | Retrieves the hardware testing state. |
| BTH_HCI_IOCTL_GET_LAST_INQUIRY_DATA | Retrieves the inquiry parameters from the cache for a particular device. |
| BTH_HCI_IOCTL_GET_BASEBAND_HANDLES | Retrieves baseband connections that are currently active. |
| BTH_HCI_IOCTL_GET_HANDLE_MODE | Retrieves the mode for active baseband connections. |
| BTH_HCI_IOCTL_GET_HARDWARE_STATUS | Retrieves the current state of the hardware, whether the card is in or out of the Bluetooth stack. |
| BTH_STACK_IOCTL_GET_CONNECTED | Retrieves the state of the hardware. |
Adding new IOCTL functions
New services can be provided by the extension layer through the standard stream driver IOControl mechanism. Applications can access these new services through the new IOCTL calls.
The following illustrates how to add new IOCTL functions.
int iRes = DeviceIoControl (
hFile, LAYER_IOCTL_SERVICE_1,
&p, sizeof(p), NULL, 0, NULL, NULL
);
