Send data to Smartphone (android) via Bluetooth (BT)

Hi,

We have only one demo SPPLEDemo Lite which can run on MSP430F5529(MSP-EXP430F5529) and then scan and connect from your android phone (example using BlueTerm app).

See http://processors.wiki.ti.com/index.php/CC256x_MSP430_Bluetopia_Basic_SPPLEDemo_Lite_APP

As you are using the launchpad, First you need to connect the UART lines. make sure you follow the first three step from here http://processors.wiki.ti.com/index.php/CC256x_Testing_Guide

and you will need to make sure that your hardware connections are fine as per the  "Hardware Porting Guidelines.pdf" file in the documentation folder of the SDK.

Hi Sundeep,

Thanks for your quick reply.

I read carefully the instruction on wiki.ti.com page, as you mentioned before, only SPPLEDemo Lite can run on MSP430F5529 (with Blueterm app). I imported this demo, modified hw connection (following Hardware Porting Guidelines.pdf)

After complie, the message:

"./lnk.cmd", line 48: error #10099-D: program will not fit into available
    memory.  placement with alignment fails for section ".text" size 0x2b12 .
    Available memory ranges:
    FLASH        size: 0x1000       unused: 0xe56        max hole: 0xe56 

Can you explain and how to fix it?

One more thing, I want add some code to interface with an sensor via SPI, How can I put on main function?

Thank you very much

First, many thanks Sundeep. I solved the problem.

Second, I have some issue:

Now I'm using MSP430 Audio Sink kit. On kit, I want using 3 touch button as A3DP Snk project with addition: when press each touch button, it's also send o char to my device (Smartphone).

For example: 

Press Back send character 'A'

Press Play/pause send character 'B'

Press Next send character 'C'

I was searching around, sb said using "SPP_Data_Write()" send data

Is that true? If true, where should I put this function

And do you have any suggestion?

Thank you very much

Hi,

Yes, But you should alo have a SPP connection before that.

When you use the Capacitive touch, ProcessCapTouch() will be called which is running as a from the Scheduler started from the main thread and from there you will call SendRemoteControlCommand() and then AUD_Send_Remote_Control_Command() to send the command.  It should be here.

once the command is set successfully and you receive a conformation from remote you will get etAUD_Remote_Control_Command_Confirmation in the callback.

For more details please have a look at the code and the documentation folder as part of the SDK

Hi,

Thank you very much, Sundeep. I solved the problem.
