The following descriptions are about the SW block diagrams.
Kernel layer
Real Time Operating System
The Wi-Fi layer is divided into four layers:
Lower MAC
SW module to control/handle HW Wi-Fi MAC/PHY and interfaces with Upper MAC layer
Upper MAC
SW module to control/handle Wi-Fi control/handle to interface with supplicant
Wi-Fi Link Layer: Interface layer between Upper MAC and supplicant
Supplicant: SW module to control/management to operate Wi-Fi operation
Network subsystem layer
Used to control/handle network operation
Main protocols are IP, TCP, and UDP
Other necessary protocols are supported
Security Layer
Crypto operation engine is ported to use crypto HW engine
TLS/TCP and DTLS/UDP APIs are supported to handle security operation:
User application layer
Variable sample codes are supported in SDK sample codes use supported APIs
TCP Client/Server, UDP Client/Server, TLS Client/Server
HTTP/HTTPs download, OTA Update usage, and MQTT usage
Customer applications can be included and implemented easily in SDK
