Enumeration Type Documentation

anonymous enum

Storage sizes for device data structure abstraction.

Enumerator:

MAX_ADDR_LEN	64 bit MAC Address
KEYSIZE	128 bit security key size

enum InterfaceEnum

Supported network interfaces.

Enumerator:

LPAN0

enum iwconfig_options

Common configuration options for IEEE 15.4 radio. Multiple options can coexist as flags.

Enumerator:

O_AUTHEN	Enable authentication mode if supported
O_ENCRYPT	Enable encryption mode if supported
O_SET_MAC_ADDRESS	Set 64 bit MAC 15.4 address
O_SET_KEY	Set security key if supported
O_SET_TX_POWER	Set the radio's transmission power
O_NOT_DEFAULT_LP	Use non-default low power settings.
O_NO_LP	Set the radio to not use low power protocol.

enum IwConfigCmdsEnum

iwconfig commands

Enumerator:

UP
DOWN
CONFIG
STATUS

enum net_device_status_flags

Flags reflecting the current status of the 15.4 radio.

Enumerator:

IFF_DOWN	Link is down.
IFF_UP	Link is up and running.
IFF_LOOPBACK	Link loopback is supported
IFF_MULTICAST	Link local IPv6 multicast is supported

Function Documentation

int16_t iwconfig	(	uint8_t	name,
		uint16_t	cmd,
		uint16_t	options,
		const net_device_t *	device_settings,
		void(*)(event_t event, void *cbargs, void *context)	iwconfig_handler,
		net_device_info_t *	dev_info,
		void *	context
	)

A system call to control and configure the wireless link interface. A continuation callback will be fired if iwconfig_handler is not NULL.

Parameters:

[in]	name	Interface name (e.g. The default 6LowPAN interface is "lpan0")
[in]	cmd	Support [UP, DOWN, CONFIG, STATUS]. See commands IwConfigCmdsEnum UP power up interface DOWN power down interface CONFIG configure the radio based on options and device_settings STATUS fills dev_info with current interface status
[in]	options	See iwconfig_options.
[in]	device_settings	Application specifies radio settings. Required for UP and CONFIG cmd.
[in]	iwconfig_handler	A continuation callback for the completion of the system call. Passing NULL here will fail the call.
[out]	dev_info	the results of the calls for the continatuion callback are stored here NULL cannot be passed.
[in]	context	application context

Returns:

0 if succeed or -1 if fail and errno is set appropriately.

Errors:

EBUSY if the underlying system is busy and cannot service the call at this time.

EINVAL if invalid parameters are passed.

Callback Descriptions

iwconfig_handler

Parameters:

[in]	event	Type is IWCONFIG in EventsEnum
[in]	cbargs	is dev_info in iwconfig()
[in]	context	is context in iwconfig()

Returns:

None.
