help starting up CC2564MODN.

Other Parts Discussed in Thread: CC2564MODN, MSP430F5438A, CC2560B

Hi all,

 I am designing a product. I'll tell you what i need to do with bluetooth.

The user will be pairing the device with his/her smartphone once he/she buys the product. Once paired, the device should establish connection automatically to paired phone even after a power down power up cycle of bluetooth.

Now bluetooth will be powered off normally (or in a deep sleep mode). When user press a switch, it send wake up signal to bluetooth module from MSP430 and bluetooth module should automatically connect with previously paired phone and send some bytes.

I have a CC2564MODN module(http://www.ti.com/product/cc2564modn) with me.

  1. Is everything i want is possible with this module? if not, can anyone suggest a module that can?
  2. I have not worked with bluetooth before, so can any anybody suggest which profile to use, and some references.
  3. Please help me with a reference PCB design for using it in a PCB I'm going to design. I will be talking to this bluetooth module through MSP430 UART. Antenna design guidelines will also be helpful.(I need to have a PCB antenna.)
  4. I found very similar product using same chip cc2564-tiwi-ub2 (http://www.ti.com/product/cc2564-tiwi-ub2) . what are the difference between this module and what i have?

Thanks.

  • Hi,

    You can use our MSP430F5438A EVM as host processes from the HW prospective  See http://processors.wiki.ti.com/index.php/CC256x_MSP430_Bluetopia_Basic_Demo_APPS#Hardware_Setup

    You can directly connect any of the CC256x device on top of the MSP430F5438A EVM board and try the hands on.

    Also visit http://processors.wiki.ti.com/index.php/CC256x 

    You can tweak or write new application to achieve what you are looking for using the software.

    Mind that deep sleep mode is different from Powering off the device.

    There will not be much difference between CC2564MODN and  LSR cc2564-tiwi-ub2( module 450-0104B) Both are buit on CC2564B chip-set. 

  • Thanks for answer.

    I am looking towards making my own PCB for bluetooth module, antenna and other components for bluetooth only.

    idea is this, I will make a PCB which is as good as an independent bluetooth module. In that board i'll have headers for UART interface. Then I'll use the MSP430 Launchpad that i have already with me for communicating through the module.

    I'm doing this because i want to use a low cost microcontroller for my final product since microcontroller's only work is sending some bytes through bluetooth. and if i start working with that microcontroller from prototyping stage itself, i won't have to spent much time in redesigning things for final product manufacturing.

    So if i get some reference design containing what all external components(like antenna, 32.768 external clock etc..) that needs to be there with CC2564MODN, it would be nice.

    Thanks

  • Hi Athul,

    The CC2564MODN and LSR cc2564-tiwi-ub2 are PCB boards with antenna, clock on it.

    What is the reason you want to design a new one? and If you don't want BLE, and just a Bluetooth module you can go for CC2560B(http://www.ti.com/product/cc2560)

    You can get any of this PCB boards and interface the UART, BT_EN, VBAT and VIO correctly with your launchpad and follow the first three steps mentioned here http://processors.wiki.ti.com/index.php/CC256x_Testing_Guide to make sure your hardware is ready.

    You can get the software from here http://www.ti.com/tool/stonestreetone-bt-sdk, and after you install the SDK you can make sure that your software configuration is correct using hardware porting guide available in the documentation folder of the SDK.

    You can have a look at the Design Guides section of our CC256x main wiki. If you want it specifically for MODN you need to wait for the release(keep checking the product page http://www.ti.com/product/cc2564modn).  

  • Hi Sundeep,

    As you had mentioned on this post that there is no much difference between TiWi uB2 and MODN.

    I need to know that If I have made my application using TiWi uB2 with EXP - MSP430 bord using Software version 1.5 then it will  work MODN module with out any software modification.

    I have made my application using SSPLEDEMO sample code.
