Instructions

To demonstrate the app, follow these steps:

1. Build and download the application to the AIROC™ board.
2. Open the ClientControl application and open the "WICED HCI" port for the device. Default baud rate configured in the application is defined by the BSP HCI_UART_DEAULT_BAUD #define, usually either 3M or 115200 depending on the board UART capabilities.
3. Use the ClientControl application to send various commands as mentioned below.
4. Run the BTSpy program to view protocol and application traces.

BR/EDR Audio Source and AVRC Target:

• The Watch AMA app can demonstrate how use to BR/EDR Audio Source and AVRC TG profiles.
• Audio Source can use I2S interrupt or SW timer to decide the timing to read PCM. For media type as 'I2S input', it will use I2S interrupt, and you need to configure 4 gpios as AIROC™ I2S PINs. For media type as 'Wav file' or 'Sine wave', it will use SW timer by calling wiced_audio_use_sw_timing(1). In general, if using the "WICED HCI" UART to transmit audio, it must either allocate I2S pins on unused pins for I2S interrupt OR use wiced_audio_use_sw_timing(1) to enable SW timer.
• Use the buttons in the ClientControl AV Source tab.
• To play a sine wave sample, set the audio frequency to the desired value (48kHz, 44.1kHz, etc.) and select the Media type as 'Sine Wave' in the UI. In this case, built-in sine wave audio is played.
• To play music from a .wav file, select the Media type as File, browse and select a .wav file, and set the audio frequency to the desired value (48kHz, 44.1kHz, etc.) In this case, audio for the .wav file is routed over the "WICED HCI" UART to the AIROC™ board.
  sinc_44100_16_L440_R1000_50s_stereo.wav in app folder can be used as the input of 44.1KHz 16bits stereo samples.
• To play music from the Line-In jack, select the Media type as 'I2S input' and set the audio frequency to the desired value (48kHz, 44.1kHz, etc.) In this case, audio from Line-In is encoded into I2S signals and routed to the AIROC™ board.
• Put an audio sink device such as Bluetooth® headphone/speaker in pairable mode.
• Click on the "Start" button from the "BR/EDR Discovery" combo box in ClientControl to find the audio sink device.
• Select the peer device in the BR/EDR Discovery combo box.
• Click the "Connect" button under the AV Source tab.
• Click the "Start Streaming" button. Music will start playing on the peer device.
• The WatchAma app uses the AVRCP Target role. Once connected to a headset/speaker, the app can send notifications for play status changes (Play, Pause, Stop) and settings changes (Repeat, Shuffle) to the peer AVRCP controller (such as a headset/speaker).
  Note: the songs shown in the AVRC TG UI and some settings such Repeat/Shuffle are for testing AVRC commands only, they do not indicate the actual media played and will not change the media played.

BTSTACK version

BTSDK AIROC™ chips contain the embedded AIROC™ Bluetooth® stack, BTSTACK. Different chips use different versions of BTSTACK, so some assets may contain variant sets of files targeting the different versions in COMPONENT_btstack_vX (where X is the stack version). Applications automatically include the appropriate folder using the COMPONENTS make variable mechanism, and all BSPs declare which stack version should be used in the BSP .mk file, with a declaration such as:

COMPONENTS+=btstack_v1
or:
COMPONENTS+=btstack_v3

Common application settings

Application settings below are common for all BTSDK applications and can be configured via the makefile of the application or passed in via the command line.

BT_DEVICE_ADDRESS

Set the BDA (Bluetooth® Device Address) for your device. The address is 6 bytes, for example, 20819A10FFEE. By default, the SDK will set a BDA for your device by combining the 7 hex digit device ID with the last 5 hex digits of the host PC MAC address.

UART

Set to the UART port you want to use to download the application. For example 'COM6' on Windows or '/dev/ttyWICED_HCI_UART0' on Linux or '/dev/tty.usbserial-000154' on macOS. By default, the SDK will auto-detect the port.

ENABLE_DEBUG

For HW debugging, configure ENABLE_DEBUG=1. See the document AIROC™-Hardware-Debugging for more information. This setting configures GPIO for SWD.

• CYW920819EVB-02/CYW920820EVB-02: SWD signals are shared with D4 and D5, see SW9 in schematics.

• CYBT-213043-EVAL/CYBT-253059-EVAL: SWD signals are routed to P12=SWDCK and P13=SWDIO. Use expansion connectors to connect VDD, GND, SWDCK, and SWDIO to your SWD Debugger probe.

• CYBT-223058-EVAL/CYW920835M2EVB-01/CYBT-243053-EVAL/CYBLE-343072-EVAL-M2B/CYBLE-333074-EVAL-M2B/CYBLE-343072-MESH/Vela-IF820-INT-ANT-DVK/Vela-IF820-EXT-ANT-DVK: SWD signals are routed to P02=SWDCK and P03=SWDIO. Use expansion connectors to connect VDD, GND, SWDCK, and SWDIO to your SWD Debugger probe.

• CYBT-263065-EVAL/CYBT-273063-EVAL: SWD signals are routed to P02=SWDCK and P04=SWDIO. Use expansion connectors to connect VDD, GND, SWDCK, and SWDIO to your SWD Debugger probe.

• CYBT-343026-EVAL/CYBT-353027-EVAL/CYBT-333047-EVAL: SWD signals are routed to P11=SWDCK and P15=SWDIO. Use expansion connectors to connect VDD, GND, SWDCK, and SWDIO to your SWD Debugger probe.

• CYBT-413055-EVAL/CYBT-413061-EVAL: SWD signals are routed to P16=SWDCK and P17=SWDIO. Use expansion connectors to connect VDD, GND, SWDCK, and SWDIO to your SWD Debugger probe.

• CYW989820EVB-01: SWDCK (P02) is routed to the J13 DEBUG connector, but not SWDIO. Add a wire from J10 pin 3 (PUART CTS) to J13 pin 2 to connect GPIO P10 to SWDIO.

• CYW920719B2Q40EVB-01: PUART RX/TX signals are shared with SWDCK and SWDIO. Remove RX and TX jumpers on J10 when using SWD. PUART and SWD cannot be used simultaneously on this board unless these pins are changed from the default configuration.

• CYW920721M2EVK-02/CYW920721M2EVB-03: The default setup uses P03 for SWDIO and P05 for SWDCK. Check the position of SW15 if using JLink with the DEBUG connector.

• CYW920706WCDEVAL: SWD debugging requires fly-wire connections. The default setup P15 (J22 pin 3 or J24 pin 1) for SWDIO and P11 (J23 pin 5 or J22 pin 4) for SWDCK.

• CYW920736M2EVB-01: SWD hardware debugging requires fly-wire connections. The only option is using P14 for SWDCK and P15 for SWDIO. These route to Arduino header J2, A1 and A0. These can be fly-wired to Arduino header J4, D4 and D5. From there the signals connect to the KitProg3 SWD bridge. In addition, the debug macros (SETUP_APP_FOR_DEBUG_IF_DEBUG_ENABLED and BUSY_WAIT_TILL_MANUAL_CONTINUE_IF_DEBUG_ENABLED) are placed in sparinit.c in code common to all applications for this device. Most applications for this device call bleprofile_GPIOInit() in subsequent code, overwriting the SWD pin configuration. To use hardware debugging after the call to bleprofile_GPIOInit(), place the debug macros in code after that call.

• CYW943012B2EVK-01: SWD signals are shared with D4 and D5.

• CYW920820M2EVB-01 & CYW920819M2EVB-01: The default setup uses P03 for SWDIO and P02 for SWDCK. Check the position of SW15 if using JLink with the DEBUG connector.

• CYW989820M2EVB-01: SWD hardware debugging requires a fly-wire connection to use P14 for SWDIO. P2 is connected directly to SWDCK / ARD_D4. Fly-wire P14 / ARD_D8 on J3.10 to J4.3 / ARD_D5 to connect SWDIO.

• SWD hardware debugging is not supported on the following:

  • CYW920721M2EVK-01
  • CYW920835REF-RCU-01
  • CYW9M2BASE-43012BT
  • CYBT-423054-EVAL
  • CYBT-423060-EVAL
  • CYBT-483056-EVAL
  • CYBT-483062-EVAL
  • CYW955572BTEVK-01
  • CYW943022BTEVK-01

DIRECT_LOAD

BTSDK chips support downloading applications either to FLASH storage or to RAM storage. Some chips support only one or the other, and some chips support both.

If a chip only supports one or the other, this variable is not applicable, applications will be downloaded to the appropriate storage supported by the device.

If a chip supports both FLASH and RAM downloads, the default is to download to FLASH, and the DIRECT_LOAD make variable may be set to 1 in the application makefile (or in the command line make command) to override the default and download to RAM.

Currently, the following chips support both FLASH and RAM download and can set DIRECT_LOAD=1 if desired:

• CYW20835
• CYW20706

Tracing

To view application traces, there are 2 methods available. Note that the application needs to configure the tracing options.

1. "WICED Peripheral UART" - Open this port on your computer using a serial port utility such as TeraTerm or PuTTY (usually using 115200 baud rate for non-Mesh apps, and 921600 for Mesh apps).
   
2. "WICED HCI UART" - Open this port on your computer using the Client Control application mentioned above (usually using 3M baud rate). Then run the BTSpy utility mentioned above.

Using BSPs (platforms)

BTSDK BSPs are located in the \mtb_shared\wiced_btsdk\dev-kit\bsp\ folder by default.

a. Selecting an alternative BSP

The application makefile has a default BSP. See "TARGET". The makefile also has a list of other BSPs supported by the application. See "SUPPORTED_TARGETS". To select an alternative BSP, use Library Manager from the Quick Panel to deselect the current BSP and select an alternate BSP. Then right-click the newly selected BSP and choose 'Set Active'. This will automatically update TARGET in the application makefile.

b. Custom BSP

To create a custom BSP from a BSP template for BTSDK devices, see the following KBA article: KBA238530

Using libraries

The libraries needed by the app can be found in in the mtb_shared\wiced_btsdk\dev-kit\libraries folder. To add an additional library to your application, launch the Library Manager from the Quick Panel to add a library. Then update the makefile variable "COMPONENTS" of your application to include the library. For example:
COMPONENTS += fw_upgrade_lib
