CC3235SF, CC1310, CC1350: Which SimpleLink MCU Should I Use?

Other Parts Discussed in Thread: CC1350, CC1310, CC3235SF

Hello,

I am designing a simple IoT device and am implementing a star network. Before I buy anything, I want to confirm my idea.

Can I simply plug a Sub 1-GHz Board into a Wi-Fi Board to make a Wi-Fi to Sub 1-GHz gateway?

I am looking to plug the CC1310 or CC1350 into the CC3235SF and then have a few stand alone CC1310 or CC1350 modules sending their data to the central gateway.

Would this idea work?

Is the CC3235SF the best Wi-Fi and most current module?

Which one is better, the CC1310 or CC1350?

If I write code for the CC1310 or CC1350, can I port it to a cheaper Sub 1-GHz module in the future?

This is what I'm generally looking for:

Thanks,

Sheldon

    And yes, I saw this page:
    www.ti.com/.../TIDC-01002

    I just want to double check on the specific MCUs I mentioned above and keep up to date with the latest hardware.

    Thanks!

    The difference between CC1310 and CC1350 is that the later also can cover 2.4 GHz.

    " a cheaper Sub 1-GHz module in the future": What did you have in mind here?

    CC3235SF sounds like a good choice, it should be possible to use this in the same way as shown in the TI design you link to.

    Thank you for your response!

    Awesome, we only need the sub 1-GHz for now, so we'll use CC1310 but good to know there's also 2.4GHz with the CC3150.

    I noticed there's a lot of options here:
    www.ti.com/.../products.html

    The cheaper ones I was referring to were the value line ones, which aren't SimpleLink, so it's probably best to stick with SimpleLink?

    Thanks, yeah I'm thinking it should be possible to do something similar to this with the CC3235SF & CC1310 by plugging them together and hopefully using the TI 15.4 software package:
    www.ti.com/.../TIDC-01002

    If anyone can confirm that this is possible as described above, confirmation would be greatly appreciated before I buy them.

    Thanks,
    Sheldon

    The combination of sub 1-GHz and wifi launchpads we have tested are shown in the TI design. If you want to use a different combination you have to check the pin out if it's possible to stack them.

    Either way you will be able to strap the required signals between the two launchpads if you for some reason are not able to stack them.

    Thanks for the insight. I will check the pinout, it seems that it should work in theory.

    I looked at the reference design and it looks like I just need a physical UART signal between the 2 boards. I will turn this into a PCB if it works out it would just be nice to simply stack them as the reference design shows.

    Thanks for your help!!
