Function Documentation

demo_dnsfound()

void demo_dnsfound	(	const char *	name,
		const ip_addr_t *	ipaddr,
		void *	callback_arg
	)

A callback triggered when a dns query is completed.

Parameters

name	pointer to the name that was looked up.
ipaddr	pointer to an ip_addr_t containing the IP address of the hostname, or NULL if the name could not be found (or on any other error).
callback_arg	a user-specified callback argument passed to dns_gethostbyname

demo_tcpconnected()

err_t demo_tcpconnected	(	void *	arg,
		struct tcp_pcb *	tpcb,
		err_t	err
	)

Callback triggered when TCP socket is connected.

Parameters

arg	unused
tpcb	a pointer to the relevant socket
err	the status of the connection

Returns

ERR_OK

demo_tcperr()

void demo_tcperr	(	void *	arg,
		err_t	err
	)

Callback triggered when the TCP socket is disconnected unexpectedly.

Parameters

arg
err

handle_cli_lwipdemo()

void handle_cli_lwipdemo	(	void *	aContext,
		uint8_t	aArgsLength,
		char *	aArgs[]
	)

Process a CLI command to change the state of the lwip demo.

Should be linked to the openthread CLI using otCliSetUserCommands.

Parameters

aContext	CLI Context
aArgsLength	size of aArgs string array
aArgs	array of arguments

init_lwipdemo()

ca_error init_lwipdemo	(	otInstance *	aInstance,
		struct ca821x_dev *	pDeviceRef
	)

Initialise the lwip demo.

Should be called once at program startup.

Parameters

aInstance	- Pointer to an OpenThread instance.
pDeviceRef	- Pointer to initialised ca821x_device_ref struct.

Returns

CA_ERROR_SUCCESS for success.
