Member Function Documentation

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

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
callbackFunction to call on state change
dataArgument to pass to callback

Implemented in AT_ControlPlane_netif.

virtual void data_received ( )
protectedpure virtual

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.

Implemented in AT_ControlPlane_netif.

virtual nsapi_size_or_error_t recv ( void *  cpdata,
nsapi_size_t  cpdata_length 
)
protectedpure virtual

Receive data over cellular control plane.

Parameters
cpdataDestination buffer for data received from control plane connection
cpdata_lengthLength of data in bytes
Returns
Number of received bytes on success, negative error code on failure.

Implemented in AT_ControlPlane_netif.

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

Send data over cellular control plane.

Parameters
cpdataBuffer of data to be sent over control plane connection
cpdata_lengthLength of data in bytes
Returns
Number of sent bytes on success, negative error code on failure.

Implemented in AT_ControlPlane_netif.
