	)		`[virtual]`

Start the interface.

Attempts to connect to a WiFi network.

Parameters:

ssid	Name of the network to connect to

nsapi_error_t gethostbyname	(	const char *	host,
		SocketAddress *	address,
		nsapi_version_t	version = `NSAPI_UNSPEC`
	)		`[virtual]`

Translates a hostname to an IP address with specific version.

The hostname may be either a domain name or an IP address. If the hostname is an IP address, no network transactions will be performed.

If no stack-specific DNS resolution is provided, the hostname will be resolve using a UDP socket on the stack.

Parameters:

address	Destination for the host SocketAddress
host	Hostname to resolve
version	IP version of address to resolve, NSAPI_UNSPEC indicates version is chosen by the stack (defaults to NSAPI_UNSPEC)

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

int scan	(	WiFiAccessPoint *	res,
		unsigned	count
	)		`[virtual]`

Scan for available networks.

This function will block.

Parameters:

Definition at line 208 of file WizFi310Interface.cpp.

int set_channel ( uint8_t channel ) [virtual]
