WF200 Use Cases
The WF200 fits well with Linux-based and RTOS-based host processors. The WF200 supports both the 802.11 split MAC and the 802.11 full MAC architectures. It communicates with the external host controller over the SPI or SDIO interface.
Linux OS Use Case
The WF200 acts as a common soft-MAC/half-MAC wireless device. The firmware exposes a Lower-MAC API compatible with Linux Kernel mac80211 subsystem and the ieee80211_ops structure. Linux distribution IP stack and supplicant are leveraged.
RTOS/Bare Metal Use Case
The WF200 acts as a full-MAC wireless device and WPA2 personal supplicant. The firmware exposes a full-MAC API at the IP packet level. It also manages WPA2 personal authentication process as well as automatic roaming. This is the particular use case addressed by this documentation.
