MCU for Wi-Fi Direct 802.11ac or 802.11a

Other Parts Discussed in Thread: CC3120

We are starting a new project for a client.  Our device needs to talk Wi-Fi Direct to an existing device which supports 802.11ac.  I assume this device can fall back to 802.11a if needed.  

- Which TI MCU's should I consider for this? 

- Is Wi-Fi Direct support readily available with example code? 

- I have not used Wi-Fi Direct before, so not sure if there are other caveats to consider.

Thanks.

Brian

    Hi Brian,

    We don't have any device that support 802.11ac.

    The Simplelink CC3220 family (www.ti.com/.../CC3220) supports Wi-Fi Direct but is only supporting 802.11b/g/n (2.4G band) and not the 802.11a (5G).
    The CC3220 consists of an MCU (Cortex-M4) and a network processor.
    The CC3120 family include only the wifi network processor and is ready for integration with an external host MCU.
    Both comes with an SDK that includes sample applications for basic functionality including WIFI-Direct.

    Wilink8 (www.ti.com/.../wl1837mod) is another Wi-Fi option from TI. It support Wifi Direct and 802.11a/b/g/n.
    It is typically integrated to an MPU running Linux, but can also interface an external MCU.
    The external MCU interfaces are supported through 3rd parties (that works with TI).
