CC3200 Bluetooth support

Other Parts Discussed in Thread: CC3200, CC256XQFNEM, CC3100

Hi,

I would like to have some add on card to support Bluetooth along with wifi support. I have checked previous queries but did not get clear option. 

Can cc256x EVM be used as add-on or booster card for CC3200 launcher EVB ?

http://www.ti.com/tool/cc256xqfnem does not indicate that. Still wanted to know if there is some possibility !

As background, I need to get hands on a development kit or EVB with wifi, bluettoth and audio (mic/speaker) support. TM4c129 evm has usb and possiblity to add on wifi (via cc3100) and BT via cc256x but no full audio (no mic and external speaker) support. CC3200 + Audiobooster pack solves audio/wifi problem but does not seem to have option to support bluetooth.

Thanks and regards,

Kumar

    You can emulate an I2S interface using TM4C129 SPI ports. There is a document how to do that.

    There is bluetooth booster pack. So, see how to make CC3200 Launchpad + audio/wifi + bluetooth work together.

    I managed to get a Roving Networks RN-42 BT device working with the CC3200,  as of yesterday :-).  It takes it a while to pair up at startup, due to the flurry of WI-FI activity taking place at the same time and frequency (I assume), but once connected, the BT link is very stable, regardless of WI-FI traffic.

    I have a 256X EVM and  its on my list to get attached, but aways down.  I do like the idea of BT and BT LTE both being available.

    Hi Kel,

    Thanks again for the support.

    On TM4c129, I will check for the ease of enabling support for I2S and hence connecting external mic/speaker. Does it have appropriate amplifier to support connecting external microphone ?

    On CC3200 launchpad, I see two booster packs for bluetooth here - http://www.ti.com/ww/en/launchpad/boosterpacks.html . Which one of these is verified to work (and also easily get connected) with CC3200 launchpad ?

    Hi Peter,

    Thanks for sharing it. For me it will be not be practical connect external BT pack with so much wiring and uncertainty. I would like to verify something easily available to quickly validate some IoT ideas. Did you try any BT booster pack mentioned on TI website ?

    Best regards,

    Kumar

    Kumar,

    No I haven;t.  I need the BT to do specific things in Master mode, and the RN-42 works well for that.  Like I said, I will connect up and experiment with the 256X eval board when I get time.  The RN-42 has six signal wires (RX, TX, STATUS, RESET, CTS, RTS) and VCC and GND, so its not that had to connect up. 'm running it off UART1.

    Peter,

    Thanks. Will look forward to your 256x evaluation. Instead of RN-42, I would like to directly verify 256x.

    Thanks,

    Kumar

    How did you manage this? I have been working trying to connect a RN-42 for a few days using the UART capabilities of the CC-3200, and so far I have been unsuccessful. The UART examples provided with the unit haven't been particularly helpful. In fact, I'm thinking about just rewriting all their functions to mimic how the Arduino does it.

    I made my own UART drivers using driver lib functions.  Ring buffers for xmit and receive and interrupt driven using the FIFOs.  Works well and I had no problems with the RN-42.  I can probably send you some code if you are interested!

    Yes please do! dejarc@uw.edu is my email address. I'm trying to write some UART drivers myself..

    I'm using pin 1 for TX and 2 for RX.
