Handling ( BT 2.1 + EDR ) Communication & UART ( with PC ) simultaneously

Other Parts Discussed in Thread: BT-MSPAUDSINK

Hi,

I am sorry if I duplicating an issue from previous posts by me.

but again, I need a help!

all what I need is to develop FW for a device, the device will be a slave that make pairing by SSP (secure simple pairing) with an application running on smartphone.

after pairing, upon a packet from the application, I need to forward this packet by UART to a PC, then the PC will return a packet that I have to transmit it back to the application.

so I need to keep connected by BT to a smartphone and by UART to a PC all the time without aborting.

(a previous version of a project was a direct UART communication between two devices, now I have develop a device as adapter BT/UART...) 

I need a help by choosing the right hardware (Evaluation board, Microprocessor, BT chip...) and the software example that I need for my device.

just I started with BT-MSPAUDSINK & CC256x MSP430 Bluetopia SDK.

can I get what I want by this board? if yes so which software example can I base on and which changes I have to do?

if no so which hardware & software I can use to achieve my aim?

Thanks.

    Hi,

    It is duplicate of http://e2e.ti.com/support/wireless_connectivity/f/660/t/376138.aspx

    simply to say, you have a connection to the PC over UART of MSP430, and  your MSP430 is connected to CC256x over another UART.  Now you have done an inquiry and have two devices and wanted to pair with the first device.

    You will send a command (pair 1, where 1 is the index of the first device from the inquiry list ) to MSP430 over UART interface to PC, and MSP430 sends this to CC256x over it's UART connections, that is sent to the remote device over Bluetooth. 

    At the same time when you receive a pin-code request from the remote device, that will be received by CC256x over bluetooth and that intern is sent to the MSP430, From there the MSP430 will send it to PC interface
