CC3220S: cc3220

Part Number: CC3220S

Is there linux driver available for CC3220 or any other host interface methodology?

    No. You can use the CC3220 AT CMD application (from the SDK) to connect through a UART (there is no driver support on the Linux side, you will need to write an app over a TTY interface).

    Typically for Linux customer we recommend the WL18xx which is more suitable (it only handles the 802.11 mac and is ready for integration with an external n/w stack) and contains a Linux driver.

    Thanks Kobi for the reply,

    Can you suggest the best approach to integrate CC3220s with linux host for best performance? UART tty based application layer is non standard and slow.

    You can replace the host interface from UART to SPI to get higher bandwidth. This will require thar you will update the at-cmd app - the SPI is not supported.

    In general, the cc32xx was not designed for high throughputs or for Linux. 

    With cc31xx (but not cc32xx), you may choose to use the network bypass mode (see chapter 6.5.4 in the nwp programmers guide). This will better fit the Linux architecture and enable to use the linux kernels network stack. However, we don't support the network device driver.

    As you can see there is no standard solution for the Simplelink in Linux. The Wilink was designed exactly for Linux.
