WiFi and Secure Socket Offload in Zephyr
summary
Zephyr gets full Wi‑Fi plus TLS offload on the TI CC3220SF LaunchXL by porting SimpleLink’s host driver and exposing the network processor’s socket APIs so TLS, DNS and TCP/IP run on the coprocessor. Implementation uses CC3220SF LaunchXL, a port of mbedTLS into Zephyr and a socket offload via IPPROTO_TLS with certificate provisioning into secure flash (UniFlash). Result: secure socket offload works on the dev board; single socket provider and no inter-interface routing are current limits.
