virtual void attach ( Callback< void(nsapi_event_t, intptr_t)>  status_cb)
virtual

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.

Remarks
Application should not call attach if using CellularContext class. Call instead CellularContext::attach as CellularDevice is dependent of this attach if CellularContext/CellularDevice is used to get device/sim ready, registered, attached, connected.
Parameters
status_cbThe callback for status changes
