kenjiArai 0:5b88d5760320 53 * The type of the interface returned can be tested by calling ethInterface(),

kenjiArai 0:5b88d5760320 56 *
kenjiArai 0:5b88d5760320 57 * The default behavior is to return the default interface for the

kenjiArai 0:5b88d5760320 59 * should set this in their targets.json to guide default selection,

kenjiArai 0:5b88d5760320 62 * The interface returned should be already configured for use such that its
kenjiArai 0:5b88d5760320 63 * connect() method works with no parameters. For connection types needing
kenjiArai 0:5b88d5760320 64 * configuration, settings should normally be obtained from JSON - the
kenjiArai 0:5b88d5760320 65 * settings for the core types are under the "nsapi" JSON config tree.

kenjiArai 0:5b88d5760320 67 * The list of possible settings for default interface type is open-ended,
kenjiArai 0:5b88d5760320 68 * as is the number of possible providers. Core providers are:
kenjiArai 0:5b88d5760320 69 *
kenjiArai 0:5b88d5760320 70 * * ETHERNET: EthernetInterface, using default EMAC and OnboardNetworkStack
kenjiArai 0:5b88d5760320 71 * * MESH: ThreadInterface or LoWPANNDInterface, using default NanostackRfPhy
kenjiArai 0:5b88d5760320 72 * * CELLULAR: OnboardModemInterface
kenjiArai 0:5b88d5760320 73 * * WIFI: None - always provided by a specific class
kenjiArai 0:5b88d5760320 74 *
kenjiArai 0:5b88d5760320 75 * Specific drivers may be activated by other settings of the
kenjiArai 0:5b88d5760320 76 * default-network-interface-type configuration. This will depend on the
kenjiArai 0:5b88d5760320 77 * target and the driver. For example a board may have its default setting
kenjiArai 0:5b88d5760320 78 * as "AUTO" which causes it to autodetect an Ethernet cable. This should
kenjiArai 0:5b88d5760320 79 * be described in the target's documentation.
kenjiArai 0:5b88d5760320 80 *
kenjiArai 0:5b88d5760320 81 * An application can override all target settings by implementing
kenjiArai 0:5b88d5760320 82 * NetworkInterface::get_default_instance() themselves - the default
kenjiArai 0:5b88d5760320 83 * definition is weak, and calls get_target_default_instance().
