This section explains the internal detail and implementation of RNWF MCC Melody component
generated library source code. The RNWF host driver library provides all the necessary
services to simplify the host application development. It encapsulates most of the RNWF
AT commands in a service layer and exposes simple API’s to develop user application.
Each services allows to register user callback function to notify responses.
These API’s construct one or more AT commands for the requested operation. The
constructed AT command frames are passed to the underlying UART driver and sent to RNWF02 Wi-Fi module. The RNWF host driver implements
a queue to handle all the asynchronous events and notifies the application using the
registered callbacks. The following block diagram illustrates various layers of the
system.Figure 3-28. System Layers
Following are the services implemented in the RNWF02
Host driver:
