CC3301MOD: SDIO or SPI for freeRTOS host

Jan Bock
Expert 3075 points
Part Number: CC3301MOD
Other Parts Discussed in Thread: CC3300MOD,

Tool/software:

  • Which communication bus (SDIO or SPI) is recommended for an application with a FreeRTOS micro?
  • If I use the CC3300MOD, is it possible to not connect the UART RX for BLE bus at all?
  • If I use the CC3301MOD, is it necessary to connect the UART RX for BLE bus in order to shut down the BLE section?

    Hey Jan,

    • Which communication bus (SDIO or SPI) is recommended for an application with a FreeRTOS micro?

    [JS]:  Our examples only support SPI for freeRTOS MCU host on CC33xx.

    • If I use the CC3300MOD, is it possible to not connect the UART RX for BLE bus at all?

    [JS]: If no BLE is needed, CC3300MOD can leave the UART lines as NC

    • If I use the CC3301MOD, is it necessary to connect the UART RX for BLE bus in order to shut down the BLE section?

    [JS] If no BLE is needed, it makes more sense to use CC3300MOD where the BLE is already disabled. However, if for some reason customer has CC3301MOD, customer does not to connect the UART lines also as BLE is disabled by default until a specific command is called to initialize the BLE.

    Best,
