HCI_WritePacket (Windows CE 5.0)
This function writes the packet to the connecting device.
int HCI_WritePacket(HCI_TYPE eType, BD_BUFFER* pOutBuffer);
Parameters
- eType
[in] Defines the HCI type. - pOutBuffer
[in] Pointer to the Bluetooth device buffer.
Return Values
TRUE on successful completion. FALSE if error has occurred. If this function returns FALSE, the stack interface to hardware will immediately be brought down by calling HCI_CloseConnection.
Remarks
The HCI_WritePacket function allocates an empty buffer with pre-allocated spaces for packet headers and trailers, which are requested by HCI_ReadHciParameters.
This function blocks while writing the packet. It returns the packet type and buffer. If an error is returned, the stack will be shut down.
HCI_WritePacket is given a buffer (BD_BUFFER) where:
- cStart defines the beginning of the HCI packet.
- The spaces between 0 and cStart and between cEnd and cSize are big enough to accommodate the transport header and trailer requested by the HCI_ReadHciParameters function.
The HCI_WritePacket function uses this buffer to store its own information. The packet type returned in *****peType can be one of the following:
- DATA_PACKET_ACL
- DATA_PACKET_SCO
- EVENT_PACKET
This function must unblock and return an error if HCI_CloseConnection is called.
Requirements
OS Versions: Windows CE .NET 4.0 and later.
Header: Bt_hcip.h.
Link Library: Btd.lib.
