Member Function Documentation

nsapi_error_t connect ( ) [virtual]

Start the interface.

Attempts to connect to a WiFi network. Requires ssid and passphrase to be set. If passphrase is invalid, NSAPI_ERROR_AUTH_ERROR is returned.

Returns:: 0 on success, negative error code on failure

Definition at line 132 of file WizFi310Interface.cpp.

nsapi_error_t connect	(	const char *	ssid,
		const char *	pass,
		nsapi_security_t	security = `NSAPI_SECURITY_NONE`,
		uint8_t	channel = `0`
	)		`[virtual]`

Start the interface.

Attempts to connect to a WiFi network.

Parameters:

ssid	Name of the network to connect to
pass	Security passphrase to connect to the network
security	Type of encryption for connection (Default: NSAPI_SECURITY_NONE)
channel	This parameter is not supported, setting it to anything else than 0 will result in NSAPI_ERROR_UNSUPPORTED

Returns:: 0 on success, or error code on failure

Definition at line 114 of file WizFi310Interface.cpp.

int disconnect ( void ) [virtual]

Stop the interface.

Returns:: 0 on success, negative on failure

Definition at line 205 of file WizFi310Interface.cpp.

int8_t get_rssi ( ) [virtual]

Gets the current radio signal strength for active connection.

Returns:: Connection strength in dBm (negative value)

Definition at line 236 of file WizFi310Interface.cpp.

virtual NetworkStack* get_stack ( ) [protected, virtual]

Provide access to the NetworkStack object.

Returns:: The underlying NetworkStack object

Definition at line 218 of file WizFi310Interface.h.

nsapi_error_t set_channel ( uint8_t channel ) [virtual]

Set the WiFi network channel - NOT SUPPORTED.

This function is not supported and will return NSAPI_ERROR_UNSUPPORTED

Parameters:

channel Channel on which the connection is to be made, or 0 for any (Default: 0)

Returns:: Not supported, returns NSAPI_ERROR_UNSUPPORTED

Definition at line 173 of file WizFi310Interface.cpp.

int set_credentials	(	const char *	ssid,
		const char *	pass,
		nsapi_security_t	security = `NSAPI_SECURITY_NONE`
	)		`[virtual]`

Set the WiFi network credentials.

Parameters:

ssid	Name of the network to connect to
pass	Security passphrase to connect to the network
security	Type of encryption for connection (defaults to NSAPI_SECURITY_NONE)

Returns:: 0 on success, or error code on failure

Definition at line 181 of file WizFi310Interface.cpp.

int socket_accept	(	void *	handle,
		void **	socket,
		SocketAddress *	address
	)		`[protected, virtual]`

Accept a new connection.

Parameters:

handle	Handle in which to store new socket
server	Socket handle to server to accept from

Returns:: 0 on success, negative on failure

Note:: This call is not-blocking, if this call would block, must immediately return NSAPI_ERROR_WOULD_WAIT

Definition at line 362 of file WizFi310Interface.cpp.

void socket_attach	(	void *	handle,
		void()(void )	callback,
		void *	data
	)		`[protected, virtual]`

Register a callback on state change of the socket.

Parameters:

handle	Socket handle
callback	Function to call on state change
data	Argument to pass to callback

Note:: Callback may be called in an interrupt context.

Definition at line 483 of file WizFi310Interface.cpp.

int socket_bind	(	void *	handle,
		const SocketAddress &	address

Parameters:

handle	Socket handle
data	The buffer in which to store the data received from the host
size	The maximum length of the buffer

Returns:: Number of received bytes on success, negative on failure

Note:: This call is not-blocking, if this call would block, must immediately return NSAPI_ERROR_WOULD_WAIT

Definition at line 396 of file WizFi310Interface.cpp.

		SocketAddress *	address,
		void *	buffer,
		unsigned	size
	)		`[protected, virtual]`

Receive a packet from a remote endpoint.

Parameters:
