5. SDK for BDE-BDM209A
CC2564CMSP432BTBLESW is CC2564C TI Dual-mode Bluetooth Stack on MSP432 MCUs. Stack
download link is:
https://www.ti.com/tool/CC2564CMSP432BTBLESW
Also, developers can find the stack user guide on this page.
Sample applications in the SDK are available for CCS, IAR, and Keil. Developers can follow the
steps in chapter 6.2 of TI stack user guide to set up the sample applications.
CCS link is:
https://www.ti.com/tool/CCSTUDIO-MSP?keyMatch=&tisearch=search-
everything&usecase=partmatches
6. Run the Demos in the CC2564CMSP432BTBLESW SDK on BDE-
BDM209A
To run the sample Demo codes in the CC2564CMSP432BTBLESW SDK on BDE-BDM209A,
please take the following step.
1. Find HRDWCFG.h file, change the I2C pins to P1.6 and P1.7
#define HRDWCFG_I2C_MODULE EUSCI_B0_BASE
#define HRDWCFG_I2C_SDA_PORT_NUM GPIO_PORT_P1
#define HRDWCFG_I2C_SDA_PIN_NUM GPIO_PIN6
#define HRDWCFG_I2C_SCL_PORT_NUM GPIO_PORT_P1

8. Run Bluetooth Stereo Audio Streaming Demo on BDE-BDM209A
8.1 With CC3200AUDBOOST board
If you are using the TI CC3200AUDBOOST board, you need to connect BDE-BDM209A and
CC3200AUDBOOST board first.

8.2 With BDE-EVM-209A board
If you are using BDE-EVM-209A, you just need to plug the BDE-EVB-209A in the BDE-EVB07
board.
Before building and burn the audio demo, developers must finish modifying the code refer to
section 6.
Connect the BDE-EVB07 board to a PC using a microUSB cable. It will show up as XDS110 Class
Application/User UART (COM x) for MSP432, under Ports (COM & LPT) in the Device manager.
Figure 8-2: Application UART COM Port
Attach a Terminal program like PuTTY to the serial port x for the board. The serial parameters
to use are 115200 Baud, 8, n, 1.
PuTTY download link:
https://www.chiark.greenend.org.uk/~sgtatham/putty/
Open the PuTTY software, and open a serial terminal as below:

Figure 8-3: PuTTY
A3DP Sink Demo Guide
The Assisted Advanced Audio Distribution Profile (A3DP) Sink allows a device to act as an
Audio sink and can control and stream audio on an Audio source.
Demo project path is:
C:\TI\Connectivity\CC256X BT\CC256x MSP432 Bluetopia SDK\v4.2.1.1\Samples\A3DPDemo_SNK
Connect the BDE-EVB07 to the PC, and use PuTTY to open the UART Port. After the firmware
is flashed into the BDE-BDM209A, reset the module using Reset button and you should see the
stack getting initialized on the PuTTY terminal and the help screen will be displayed, which shows
all of the commands.

Plug your earphone into the Line Out Jack on the BDE-EVM-209A board. A3DP sink demo will
advertise automatic after reset. Use your smartphone to connect and pair with the module in the
Bluetooth settings menu. After the link is established, you should hear the sound via earphone if
the smartphone is playing music.

By default, A3DP sink demo select CODEC_LINE_OUT as output device, as below:

If developers want to use the speaker as the output device. Change the ‘OutputLine’ value, as
below:
But the stack doesn’t implement the speaker initialization code. So, developers should add
the below code in line 391 of CC3200AUDBOOST.c.
case CODEC_SPEAKER:
// Select Page 1
CodecPageSelect(1);
// P1, R14, b3. Left_DAC -> LOL (1)
CodecRegWrite(CODEC_REG_LOL_SEL, 0x08);
// P1, R15, b3. Right_DAC -> LOR (1)
CodecRegWrite(CODEC_REG_LOR_SEL, 0x08);

// P1, R18, b6. LOL Driver = Not Muted (0)
// P1, R18, b5-0. LOL Driver Gain = 0dB
CodecRegWrite(CODEC_REG_LOL_DRV_GAIN, 0x00);
// P1, R19, b6. LOR Driver = Not Muted (0)
// P1, R19, b5-0. LOR Driver Gain = 0dB
CodecRegWrite(CODEC_REG_LOR_DRV_GAIN, 0x00);
// P1, R9, b3. LOL Driver = Power Up (1)
// P1, R9, b2. LOR Driver = Power Up (1)
CodecRegWrite(CODEC_REG_OUT_DRV_CTRL ,0x0C);
// Select Page 0
CodecPageSelect(0);
// P0, R65, b7-0. Left_DAC Volume = 0dB
CodecRegWrite(CODEC_REG_LDAC_VOL, 0x00);
// P0, R66, b7-0. Right_DAC Volume = 0dB
CodecRegWrite(CODEC_REG_RDAC_VOL, 0x00);
// P0, R63, b7. Right_DAC = Power Up (1)
// P0, R63, b6. Right_DAC = Power Up (1)
// P0, R63, b5-4. Left_DAC = Left Channel (01)
// P0, R63, b3-2. Right_DAC = Right Channel (01)
// P0, R63, b1-0. Soft-Stepping = Disabled (10)
CodecRegWrite(CODEC_REG_DAC_CTRL_1, 0xD6);
// P0, R64, b7. Right_DAC_Off = Zero_Data (0)
// P0, R64, b6-4. DAC_Auto_Mute = Disabled (000)
// P0, R64, b3. Left_DAC = Not muted (0)
// P0, R64, b2. Right_DAC = Not muted (0)
// P0, R64, b1-0. DAC_Master_Vol = Independent L/R (00)
CodecRegWrite(CODEC_REG_DAC_CTRL_2, 0x00);
break;
And then , add below code in line 132 of CC3200AUDBOOST.h:
#define CODEC_REG_LOL_SEL 0x0E
#define CODEC_REG_LOR_SEL 0x0F
#define CODEC_REG_LOL_DRV_GAIN 0x12
#define CODEC_REG_LOR_DRV_GAIN 0x13
