Detailed Description

PPPInterface class Implementation of the NetworkInterface for an PPP-service.

This class provides the necessary glue logic to create a NetworkInterface based on an PPP and an OnboardNetworkStack.

Definition at line 34 of file PPPInterface.h.

Member Typedef Documentation

◆ hostbyname_cb_t

typedef mbed::Callback<void (nsapi_value_or_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.

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 303 of file NetworkInterface.h.

Constructor & Destructor Documentation

◆ PPPInterface()

PPPInterface	(	PPP &	ppp = `PPP::get_default_instance()`,
		OnboardNetworkStack &	stack = `OnboardNetworkStack::get_default_instance()`
	)

Create an PPP-based network interface.

The default arguments obtain the default PPP, which will be target- dependent (and the target may have some JSON option to choose which is the default, if there are multiple). The default stack is configured by JSON option nsapi.default-stack.

Due to inability to return errors from the constructor, no real work is done until the first call to connect().

Parameters

ppp	Reference to PPP to use
stack	Reference to onboard-network stack to use

Member Function Documentation

◆ set_network()

nsapi_error_t set_network	(	const SocketAddress &	ip_address,
		const SocketAddress &	netmask,
		const SocketAddress &	gateway
	)

overridevirtual

Configure this network interface to use a static IP address.

Implicitly disables DHCP, which can be enabled in set_dhcp. Requires that the network is disconnected.

Parameters

ip_address	SocketAddress object containing the local IP address
netmask	SocketAddress object containing the local network mask
gateway	SocketAddress object containing the local gateway

Return values

NSAPI_ERROR_OK	on success
NSAPI_ERROR_UNSUPPORTED	if this function is unsupported

Reimplemented from NetworkInterface.

◆ connect()

nsapi_error_t connect ( )

overridevirtual

Connect to a network.

This blocks until connection is established, but asynchronous operation can be enabled by calling NetworkInterface::set_blocking(false).

In asynchronous mode this starts the connection sequence and returns immediately. Status of the connection can then checked from NetworkInterface::get_connection_status() or from status callbacks.

NetworkInterface internally handles reconnections until disconnect() is called.

Returns: NSAPI_ERROR_OK if connection established in blocking mode.; NSAPI_ERROR_OK if asynchronous operation started.; NSAPI_ERROR_BUSY if asynchronous operation cannot be started. Implementation guarantees event generation, which can be used as an trigger to reissue the rejected request.; NSAPI_ERROR_IS_CONNECTED if already connected.; negative error code on failure.

Implements NetworkInterface.

◆ disconnect()

nsapi_error_t disconnect ( )

overridevirtual

Disconnect from the network.

This blocks until interface is disconnected, unless interface is set to asynchronous (non-blocking) mode by calling NetworkInterface::set_blocking(false).

Returns: NSAPI_ERROR_OK on successfully disconnected in blocking mode.; NSAPI_ERROR_OK if asynchronous operation started.; NSAPI_ERROR_BUSY if asynchronous operation cannot be started. Implementation guarantees event generation, which can be used as an trigger to reissue the rejected request.; NSAPI_ERROR_NO_CONNECTION if already disconnected.; negative error code on failure.

Implements NetworkInterface.

◆ get_ip_address()

nsapi_error_t get_ip_address ( SocketAddress * address )

char * get_interface_name ( char * interface_name )

overridevirtual

Get the network interface name.

Returns: Null-terminated representation of the network interface name or null if interface not exists

Reimplemented from NetworkInterface.

void set_as_default ( )

overridevirtual

Set network interface as default one.

Reimplemented from NetworkInterface.

◆ attach()

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

overridevirtual

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. Only one callback can be registered at a time.

To unregister a callback call with status_cb parameter as a zero.

NOTE: Any callbacks registered with this function will be overwritten if add_event_listener() API is used.

Parameters

status_cb The callback for status changes.

Reimplemented from NetworkInterface.

◆ get_connection_status()

nsapi_connection_status_t get_connection_status ( ) const

overridevirtual

Get the connection status.

Returns: The connection status (

See also: nsapi_types.h).

Reimplemented from NetworkInterface.

◆ set_blocking()

nsapi_error_t set_blocking ( bool blocking )

overridevirtual

Set asynchronous operation of connect() and disconnect() calls.

By default, interfaces are in synchronous mode which means that connect() or disconnect() blocks until it reach the target state or requested operation fails.

Parameters

blocking Use false to set NetworkInterface in asynchronous mode.

Returns: NSAPI_ERROR_OK on success; NSAPI_ERROR_UNSUPPORTED if driver does not support asynchronous mode.; negative error code on failure.

Reimplemented from NetworkInterface.

◆ set_stream()

void set_stream ( mbed::FileHandle * stream )

Sets file stream used to communicate with modem.

Parameters

stream Pointer to file handle

◆ set_ip_stack()

void set_ip_stack ( nsapi_ip_stack_t ip_stack )

Sets IP protocol versions of IP stack.

Parameters

ip_stack IP protocol version

◆ set_credentials()

void set_credentials	(	const char *	uname,
		const char *	password
	)

Sets user name and password for PPP protocol.

Parameters

uname	User name
password	Password

◆ getppp()

PPP & getppp ( ) const

Provide access to the PPP.

This should be used with care - normally the network stack would control the PPP, so manipulating the PPP while the stack is also using it (ie after connect) will likely cause problems.

Returns: Reference to the PPP in use

Definition at line 113 of file PPPInterface.h.

◆ get_stack()

NetworkStack * get_stack ( )

finalprotected

Provide access to the underlying stack.

Returns: The underlying network stack

◆ get_default_instance()

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:

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().

◆ get_hostname()

virtual const char * get_hostname ( )

virtualinherited

Get hostname.

Returns: Hostname if configured, null otherwise

Reimplemented in EMACInterface.

◆ set_hostname()

virtual nsapi_error_t set_hostname ( const char * hostname )

virtualinherited

Set hostname.

Parameters

hostname Hostname string

Return values

NSAPI_ERROR_OK	on success
NSAPI_ERROR_UNSUPPORTED	if this feature is not supported
NSAPI_ERROR_PARAMETER	if hostname is not valid
NSAPI_ERROR_BUSY	if hostname couldn't be set (e.g. for LwIP stack, hostname can only be set before calling `EthernetInterface::connect` method)

Reimplemented in EMACInterface.

◆ get_mac_address()

virtual const char * get_mac_address ( )

virtualinherited

Get the local MAC address.

Provided MAC address is intended for info or debug purposes and may be not provided if the underlying network interface does not provide a MAC address.

Returns: Null-terminated representation of the local MAC address or null if no MAC address is available.

Reimplemented in InterfaceNanostack, and EMACInterface.

◆ set_mac_address()

virtual nsapi_error_t set_mac_address	(	uint8_t *	mac_addr,
		nsapi_size_t	addr_len
	)

virtualinherited

Set the MAC address to the interface.

Set the provided MAC address on the network interface. The address must be unique globally. The address must be set before calling the interface connect() method.

Not all interfaces are supporting MAC address set and an error is not returned for this method call. Verify the changed MAC address by checking packet captures from the used network interface.

6-byte EUI-48 MAC addresses are used for Ethernet while Mesh interface is using 8-byte EUI-64 address.

More information about obtaining MAC address can be found from: https://standards.ieee.org/products-services/regauth/index.html

Parameters

mac_addr	Buffer containing the MAC address in hexadecimal format.
addr_len	Length of provided buffer in bytes (6 or 8)

Return values

NSAPI_ERROR_OK	on success
NSAPI_ERROR_UNSUPPORTED	if this feature is not supported

virtualinherited

Get the IPv6 link local address.

Parameters

address SocketAddress representation of the link local IPv6 address

Return values

virtualinherited

Translate a hostname to the multiple IP addresses (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.
