Detailed Description

Wi-SUN mesh network interface class.

Configure Nanostack to use Wi-SUN protocol.

Definition at line 26 of file WisunInterface.h.

Member Typedef Documentation

typedef mbed::Callback<void (nsapi_error_t result, SocketAddress *address)> hostbyname_cb_t
inherited

Hostname translation callback (for use with gethostbyname_async()).

Callback will be called after DNS resolution completes or a failure occurs.

Note
Callback should not take more than 10ms to execute, otherwise it might prevent underlying thread processing. A portable user of the callback should not make calls to network operations due to stack size limitations. The callback should not perform expensive operations such as socket recv/send calls or blocking operations.
Parameters
resultNSAPI_ERROR_OK on success, negative error code on failure.
addressOn success, destination for the host SocketAddress.

Definition at line 219 of file NetworkInterface.h.

Constructor & Destructor Documentation

Create an uninitialized WisunInterface.

Must initialize to initialize the mesh on a phy.

Definition at line 33 of file WisunInterface.h.

Create an initialized WisunInterface.

Member Function Documentation

virtual nsapi_error_t add_dns_server ( const SocketAddress address,
const char *  interface_name 
)
virtualinherited

Add a domain name server to list of servers to query.

Parameters
addressAddress for the dns host.
Returns
NSAPI_ERROR_OK on success, negative error code on failure.

Implements DNS.

void add_event_listener ( mbed::Callback< void(nsapi_event_t, intptr_t)>  status_cb)
inherited

Add event listener for interface.

This API allows multiple callback to be registered for a single interface. When first called, internal list of event handlers are created and registered to interface through attach() API.

Application may only use attach() or add_event_listener() interface. Mixing usage of both leads to undefined behavior.

Parameters
status_cbThe callback for status changes.
virtual void attach ( mbed::Callback< void(nsapi_event_t, intptr_t)>  status_cb)
virtualinherited

Register callback for status reporting.

The specified status callback function will be called on status changes on the network. The parameters on the callback are the event type and event-type dependent reason parameter.

Parameters
status_cbThe callback for status changes

Reimplemented from NetworkInterface.

Returns
Pointer to requested interface type or NULL if this class doesn't implement the interface.

Definition at line 347 of file NetworkInterface.h.

virtual CellularInterface* cellularInterface ( )
virtualinherited

Return pointer to a CellularInterface.

Returns
Pointer to requested interface type or NULL if this class doesn't implement the interface.

Reimplemented in CellularInterface.

Definition at line 424 of file NetworkInterface.h.

virtual nsapi_error_t connect ( )
virtualinherited

Start the interface.

Returns
0 on success, negative error code on failure

Implements NetworkInterface.

virtualinherited

Stop the interface.

Returns
0 on success, negative error code on failure

Implements NetworkInterface.

virtual EMACInterface* emacInterface ( )
virtualinherited

Return pointer to an EMACInterface.

Returns
Pointer to requested interface type or NULL if this class doesn't implement the interface.

Reimplemented in EMACInterface.

Definition at line 355 of file NetworkInterface.h.

virtual EthInterface* ethInterface ( )
virtualinherited

Return pointer to an EthInterface.

Returns
Pointer to requested interface type or NULL if this class doesn't implement the interface.

Reimplemented in EthInterface.

Definition at line 321 of file NetworkInterface.h.

virtual nsapi_connection_status_t get_connection_status ( ) const
virtualinherited

Get the connection status.

Returns
The connection status according to ConnectionStatusType

Reimplemented from NetworkInterface.

static MeshInterface* get_default_instance ( )
staticinherited

Get the default Mesh interface.

This is provided as a weak method so applications can override. Default behavior is to get the target's default interface, if any.

Returns
pointer to interface, if any.
static NetworkInterface* get_default_instance ( )
staticinherited

Return the default network interface.

Returns the default network interface, as determined by JSON option target.network-default-interface-type or other overrides.

The type of the interface returned can be tested by calling ethInterface(), wifiInterface(), meshInterface(), cellularInterface(), emacInterface() and checking for NULL pointers.

The default behavior is to return the default interface for the interface type specified by target.network-default-interface-type. Targets should set this in their targets.json to guide default selection, and applications may override.

The interface returned should be already configured for use such that its connect() method works with no parameters. For connection types needing configuration, settings should normally be obtained from JSON - the settings for the core types are under the "nsapi" JSON config tree.

The list of possible settings for default interface type is open-ended, as is the number of possible providers. Core providers are:

Specific drivers may be activated by other settings of the default-network-interface-type configuration. This will depend on the target and the driver. For example a board may have its default setting as "AUTO" which causes it to autodetect an Ethernet cable. This should be described in the target's documentation.

An application can override all target settings by implementing NetworkInterface::get_default_instance() themselves - the default definition is weak, and calls get_target_default_instance().

virtual const char* get_gateway ( )

nsapi_version_t  version = NSAPI_UNSPEC,
const char *  interface_name = NULL 
)
virtualinherited

Translate a hostname to an IP address with specific version using network interface name.

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
hostHostname to resolve.
addressPointer to a SocketAddress to store the result.
versionIP version of address to resolve, NSAPI_UNSPEC indicates version is chosen by the stack (defaults to NSAPI_UNSPEC).

hostbyname_cb_t  callback,
nsapi_version_t  version = NSAPI_UNSPEC,
const char *  interface_name = NULL 
)
virtualinherited

Translate a hostname to an IP address (asynchronous) using network interface name.

The hostname may be either a domain name or a dotted 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.

Call is non-blocking. Result of the DNS operation is returned by the callback. If this function returns failure, callback will not be called. In case result is success (IP address was found from DNS cache), callback will be called before function returns.

Parameters
hostHostname to resolve.
callbackCallback that is called for result.
versionIP version of address to resolve, NSAPI_UNSPEC indicates version is chosen by the stack (defaults to NSAPI_UNSPEC).
interface_nameNetwork interface name
Returns

Function overwrites parameters defined by Mbed OS configuration.

Parameters
regulatory_domainValues defined in Wi-SUN PHY-specification. Use 0xff to use leave parameter unchanged.
operating_classValues defined in Wi-SUN PHY-specification. Use 0xff to use leave parameter unchanged.
