The following table shows the IOCTLs available to OS developers for the Bluetooth stack extension layer, with a description of the purpose of each.
| Programming element | Description |
|---|---|
| BTH_HCI_IOCTL_GET_BASEBAND_HANDLES | This IOCTL retrieves baseband connections that are currently active. |
| BTH_HCI_IOCTL_GET_BD_FOR_HANDLE | This IOCTL retrieves the address of a peer Bluetooth–based device for connection handle. |
| BTH_HCI_IOCTL_GET_COMMANDSIZE | This IOCTL retrieves the loopback status. |
| BTH_HCI_IOCTL_GET_ERRORS | This IOCTL retrieves the number of hardware errors. |
| BTH_HCI_IOCTL_GET_FLOW | This IOCTL retrieves host flow control status. |
| BTH_HCI_IOCTL_GET_HANDLE_FOR_BD | This IOCTL retrieves the connection handle for a Bluetooth device if it is connected. |
| BTH_HCI_IOCTL_GET_HANDLE_MODE | This IOCTL retrieves the mode for active baseband connections. |
| BTH_HCI_IOCTL_GET_HARDWARE_STATUS | This IOCTL retrieves the current state of the hardware, whether the card is in or out of the Bluetooth stack. |
| BTH_HCI_IOCTL_GET_INQUIRY | This IOCTL retrieves the inquiry status. The status is TRUE if currently in inquiry. |
| BTH_HCI_IOCTL_GET_LAST_INQUIRY_DATA | This IOCTL retrieves the inquiry parameters from the cache for a particular device. |
| BTH_HCI_IOCTL_GET_LOOPBACK | This IOCTL retrieves the loopback status. |
| BTH_HCI_IOCTL_GET_NUM_ONDEVICE | This IOCTL retrieves the number of unconfirmed packets sent to the hardware. |
| BTH_HCI_IOCTL_GET_NUM_PENDING | This IOCTL retrieves the number of confirmed and pending packets that are in execution on the hardware. |
| BTH_HCI_IOCTL_GET_NUM_UNSENT | This IOCTL retrieves the number of packets pending before being sent to the card. |
| BTH_HCI_IOCTL_GET_PERIODIC_INQUIRY | This IOCTL retrieves periodic inquiry status. The status is TRUE if currently in periodic inquiry. |
| BTH_HCI_IOCTL_GET_UNDER_TEST | This IOCTL retrieves the hardware testing state. |
| BTH_HCI_IOCTL_HANDLE_AUTHENTICATED | This IOCTL retrieves the authentication status of the connection. |
| BTH_HCI_IOCTL_HANDLE_ENCRYPTED | This IOCTL retrieves the encryption status of the connection. |
| BTH_STACK_IOCTL_GET_CONNECTED | This IOCTL retrieves state of the hardware. |
| BTH_HCI_IOCTL_GET_SCO_PARAMETERS | This IOCTL retrieves information about a SCO connection. |
| BTH_HCI_IOCTL_GET_BASEBAND_CONNECTIONS | This IOCTL retrieves information about the baseband connection. |
| BTH_HCI_IOCTL_GET_REMOTE_COD | This IOCTL retrieves the remote class of device (COD) of the peer device. |
