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
