CC3135: SimpleLink Connections

Part Number: CC3135
Other Parts Discussed in Thread: CC2642R

Hey Team,

I am working with a customer on a solution that involves the CC3135 + CC2642R + MSP432E4.

I am wondering what minimum physical interconnect is assumed by the SimpleLink suite to make these three devices interoperate and be as “plug-and-play” as possible.

What are the main connections that need to be made to enable the SimpleLink functionality?

Best,
Dajon McGill

  • Hi Dajon,

    I'm assuming the customer is using the MSP432E4 as the main microcontroller of the system. This would make sense as there are SDK plugin demos available for the MSP432E4 with both the CC3135 and CC26x2 devices.

    • The Wi-Fi host driver requires a SPI interface (UART is also supported, but this driver is currently not plug-and-play), plus 2 GPIOs (nHIB and IRQ). Please see the datasheet and Wi-Fi plugin for details.
    • The BLE interface requires UART and 3 GPIOs (MRDY, SRDY, and Reset). You can find more details in the BLE plugin user's guide.
    • If you want to use the CC3135 to manage 2.4GHz radio coexistence, you will also need to connect a coex GPIO between the CC3135 and CC26x2.

    Keep in mind these three LaunchPads may not all stack together out of the box. If you want to stack the LaunchPads, the pin configuration for the CC26x2 interface is easy to change by generating a new SNP image.

    Best regards,

    Sarah
