Other Parts Discussed in Thread: CC3200

Hello All,

We are trying to re-create a scenario where I need help. 

Smartphone - 802.11 (Chip1) - 802.11(Chip2)- External AP- Internet

Questions

a. Could we have 2 chips on one board ? OR do I need two seperate boards

b. Does anyone have any scripts / programs that have leveraged 2 boards stacked together (and NIC as bridged)

thanks

SH

    I do not see any issue with having 2 CC3200 chips on the same board. The CC3200 is a fully self contained MCU, so you could communicate (bridge) between the chips using its on-board peripherals, either SPI, I2C or UART.

    The CC3200 SDK has example code for each of the peripherals I mentioned above, it also includes examples for the WIfi comms examples for Access Point Mode (the CC3200 connected to the SmartPhone) and Station Mode (the CC3200 connected to the External AP). All you need to do is combine the code together.

    You could prototype this solution using 2 CC3200 LaunchPads, and connect between the LaunchPads using the headers.

    Thanks Glenn.

    The only question remaining is porting the actual code that is written in Linux. I see RTOS but no linux kernel (out of the box). 

    Please suggest.

    thanks

    Linux is not supported on the CC3200. You would be wanting to look at another device other than an ARM Cortex M4 based one if you wanted Linux.

    You may want to make sure you have enough space if the code was originally written for Linux. You have a little less than 256KB for code and data.
