Member Function Documentation

send()

virtual nsapi_size_or_error_t send ( const void *  cpdata, nsapi_size_t  cpdata_length  )

protectedvirtual

Send data over cellular control plane.

Parameters

cpdata	Buffer of data to be sent over control plane connection
cpdata_length	Length of data in bytes

Returns

Number of sent bytes on success, negative error code on failure.

Implements ControlPlane_netif.

recv()

virtual nsapi_size_or_error_t recv ( void *  cpdata, nsapi_size_t  cpdata_length  )

protectedvirtual

Receive data over cellular control plane.

Parameters

cpdata	Destination buffer for data received from control plane connection
cpdata_length	Length of data in bytes

Returns

Number of received bytes on success, negative error code on failure.

Implements ControlPlane_netif.

data_received()

virtual void data_received ( )

protectedvirtual

Receives data from the control plane PDP context.

This function is called by cellular PDP context when data is received from network. It will invoke the callback set by the above attach.

Implements ControlPlane_netif.

attach()

virtual void attach ( void(*)(void *)  callback, void *  data  )

protectedvirtual

Register a callback on state change of the socket.

The specified callback will be called on state changes such as when the socket can recv/send successfully and on when an error occurs. The callback may also be called spuriously without reason.

The callback may be called in an interrupt context and should not perform expensive operations such as recv/send calls.

Parameters

callback	Function to call on state change
data	Argument to pass to callback

Implements ControlPlane_netif.
