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.
- Is everything i want is possible with this module? if not, can anyone suggest a module that can?
- I have not worked with bluetooth before, so can any anybody suggest which profile to use, and some references.
- 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.)
- 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.
