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

result	Negative error code on failure or value that represents the number of DNS records
address	On success, destination for the host SocketAddress.

Definition at line 284 of file NetworkInterface.h.

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

Parameters

address

Address for the dns host.

Returns

NSAPI_ERROR_OK on success, negative error code on failure.

Implements DNS.

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.

Warning

This version of the function does not use the std::nothrow feature. Subsequently, the function may fail to allocate memory and cause a system error. To use the new version with the changes, set "nsapi.add-event-listener-return-change": 1 in the target overrides section in your mbed_app.json file.

Parameters

status_cb

The callback for status changes.

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_cb

The callback for status changes

Reimplemented from NetworkInterface.

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.

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:

• ETHERNET: EthernetInterface, using default EMAC and OnboardNetworkStack
• MESH: ThreadInterface or LoWPANNDInterface, using default NanostackRfPhy
• CELLULAR: OnboardModemInterface
• WIFI: None - always provided by a specific class

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().

Set Wi-SUN network size.

Function stores network size parameter to the mbed-mesh-api and uses it when connect() is called for the next time. If a device is already connected to the Wi-SUN network, then the device will restart network discovery after changing the network size.

It is recommended to set the correct network size because some Wi-SUN network configuration parameters are adjusted based on the selected network size. A network configured for a small amount of devices may not work optimally for large number of devices. This is because the network bandwidth is divided with all the devices in the network. Enough bandwidth must be reserved for application data usage as well as the Wi-SUN network operations. In addition, the application should adapt to the network characteristics by using the InternetSocket methods get_stagger_estimate_to_address() and get_rtt_estimate_to_address().

The network size is measured as hundreds of devices that are expected to join to the network. For example, for a 400-device network set network size to 4.

The Wi-SUN stack will automatically adjust timing and RPL configuration values based on the selected network size and data rate. If a customized timing or RPL values are needed, the APIs below should be invoked after changing the network size:

• set_timing_parameters() to set timing settings to the Wi-SUN interface.
• rpl_parameters_set() to set RPL settings to the Border Router interface.

By default the Wi-SUN stack is configured to use a few hundreds of devices.

The network size should be set to 0 when running certification tests.

Parameters

network_size

Network size in hundreds of devices (e.g. 12 for 1200 devices), 0 for certificate testing.

Returns

MESH_ERROR_NONE on success.

MESH_ERROR_UNKNOWN in case of failure.

Set own certificate and private key reference to the Wi-SUN network.

Function can be called several times if intermediate certificates are used. Then each call to the function adds a certificate reference to own certificate chain. Certificates are in bottom up order i.e. own certificate is given first and the top certificate is given last.

PEM formatted certificates must use either "\n" or "\r\n" as line separator. PEM formatted certificates must be NUL terminated and the NUL terminator is counted to certificate length.

It is possible to add multiple PEM certificates concatenated together in one call set_own_certificate(). In that case certificates are in bottom up order i.e. own certificate is given first and the top certificate is given last. NUL terminator is added after the last concatenated certificate and the NUL terminator is counted to total concatenated certificate length.

Function must be called before connecting the device i.e before call to connect() method. Function will not copy certificate or key, therefore addresses must remain valid.

Parameters

cert	Certificate address.
cert_len	Certificate length in bytes.
cert_key	Certificate key address.
cert_key_len	Certificate key length in bytes.

Returns

MESH_ERROR_NONE on success.
