WFx FMAC driver

The WFx FMAC driver is a software resource meant to allow a host to communicate with the WFx Wi-Fi transceiver. The API exposed by the driver give control over the WFx Wi-Fi capabilities. In addition, the API enables data transfer at the IP level. This means that the host requires an IP stack if it wants to send/receive Ethernet frames.

Host software architecture

In this section, the FMAC driver is described as well as the requirements for the host running it:

• Initialization and configuration
• Host requirements
• Device power save mechanism
• Host API
• General API
• FMAC API
