Using both Wi-Fi and Bluetooth with Launchpad

Hi,

I am a student at The University of Texas working on a senior design project. We are using the MSP430 Launchpad with the G2553 MCU. We would like to be able to take in data via Bluetooth and then eventually output data via Wi-Fi. We have a CC3000 boosterpack already and are wondering if it is possible to also add a Bluetooth boosterpack with out any issues. Or if there are combination Wi-Fi and Bluetooth boards available. If anyone has done something similar or has any guidance it would be greatly appreciated.

Thanks

    Using G2553? Really?

    Yes. You seem to have an opinion against this. Could you explain your concern?

    Personally I would never chose chip having 8KB code flash for bluetooth or wifi application alone, not to mention both in single project. BT and WiFi are quite complex stuff so G2553 does not seem to be good choice for particular application. Better think of Tiva Launchpad while it's not too late

    Yeah, this has been one of our big concerns and the kind of information I was looking for out of this post. Our project started out needing WiFi only, then we got an opportunity to add another peripheral that uses Bluetooth. Right now we are just trying to determine if the Bluetooth will be possible to add. 

    We picked the MSP430 because our design needs to run on a small battery and be portable, so power consumption is a big issue. 

    Seems like we may have to bail on the Bluetooth peripheral. 

    With just using the WiFi all we are doing is taking in accelerometer data and sending it out over the WiFi. Think that is too much to handle for the G2553?

    Thanks!

    WiFi and low power consumption? Small battery? Are you kidding? Did you read CC3000 datasheet, did you check TX/RX currents?

    I don't know - as you already noticed I am not optimist here.
