CC3200: cc3200 as spi master for cc2640 BLE chip

Part Number: CC3200
Other Parts Discussed in Thread: CC2640,

Hi team,

we are interested to use  CC3200 network controller as spi master for CC2640 in our application can we controller wifi functionality and spi operations simultaneously.

Kiran

  • Hi Kiran,

    As start point you can see this reference design - www.ti.com/.../TIDC-BLE-TO-WIFI-IOT-GATEWAY

    Biggest challenge in this topic is properly design RF parts, to not be there interferences between both 2.4GHz radios.

  • Hi Kiran,

    Yes, you can do both Wi-Fi operations and use the applications SPI interface at the same time. Jan is also correct, there is no HW coexistence mechanism in the CC3200 device. Designing to pass certification with coexistence between the two radios is a challenge so it is not recommended to have them both enabled at the same time in your application.
