int	Wifi_RawTxFrame (u16 datalen, u16 rate, const void *src)
	Send a raw 802.11 frame at a specified rate.

Detailed Description

Typedef Documentation

WifiPacketHandler

typedef void(* WifiPacketHandler) (int, int)

Handler of RAW packets received in this console.

The first parameter is the packet address. It is only valid while the called function is executing. The second parameter is packet length.

Call Wifi_RxRawReadPacket(adddress, length, buffer) while in the packet handler function to retreive the data to a local buffer.

From this handler The IEEE 802.11 header can be read, followed by the packet data.

Function Documentation

Wifi_RawSetPacketHandler()

void Wifi_RawSetPacketHandler

(

WifiPacketHandler

wphfunc

)

Set a handler to process all raw incoming packets.

Parameters

wphfunc

Pointer to packet handler (see WifiPacketHandler for info).

Wifi_RawTxFrame()

int Wifi_RawTxFrame	(	u16	datalen,
		u16	rate,
		const void *	src
	)

Send a raw 802.11 frame at a specified rate.

Warning

This function doesn't include the IEEE 802.11 frame header to your data, you need to make sure that your data is prefixed by a valid header before calling this function.

Parameters

datalen	The length in bytes of the frame to send from beginning of 802.11 header to end, but not including CRC.
rate	The rate to transmit at (Specified as mbits/10, 1mbit=0x000A, 2mbit=0x0014)
src	Pointer to the data to send (should be halfword-aligned).

Returns

0 on success (not enough space in queue), -1 on error.

Wifi_RxRawReadPacket()

void Wifi_RxRawReadPacket	(	u32	base,
		u32	size_bytes,
		void *	dst
	)

Allows user code to read a packet from within the WifiPacketHandler function.

Parameters

base	The base address of the packet in the internal buffer.
size_bytes	Number of bytes to read. It actually reads ((number + 1) & ~1) bytes
dst	Location for the data to be read into. It must be aligned to 16 bits.
