Hello Infineon support team.

According to the attachment, since Bluetooth SDK 3.3, CYW920721B2EVK-02 evaluation kit became out of support.
And The CYW920721M2EVK-02 is the replacement for this kit. We are no longer able to refer CYW920721B2EVK-02 BSP on the latest ModusToolBox.

However, at least CYW920721M2EVK-02 sample app "Audio_Headset_and_Speaker" does not work well on CYW920721B2EVK-02 EVB.
Because the defined pin assignment is different between them.

Please advice me to port CYW920721M2EVK-02 sample app to CYW920721B2EVK-02 on ModusToolBox?

Thanks,
Tayo

Hello Zhang-san

This issue was resolved by following modifications.
========================================
- Comment out below code in Makefile
CY_APP_DEFINES += -DPLATFORM_LED_DISABLED

- Replace following source code from BTSDK rev 3.2 environment.
wiced_platform.h
platform.c
cycfg.c
cycfg.h
cycfg_notices.h
cycfg_pins.c
cycfg_pins.h
cycfg_routing.h
========================================

Thank you for your kindly support.

Thanks,
Tayo

I compared the platform files for the two bsp. Following are the differences between them.

Could you try to change them and try again?

Also, if the demo still works abnormal, please specify the problem so we can check it.

Hello Zhang-san

I got it. We are testing, thank you. 

BTW, I would like to refer the schematic of CYW920721M2EVK EVB. Where can I find it?

Thanks,

Tayo

Hello Zhang-san

Thank you for the schematic releasing.

We modified the wiced_platform.h accordance with your advice. Then CYW920721B2EVK-02 works fine the BT connection using  a sample app "Audio_Headset_and_Speaker". 

However LED2(D2) on the EVB does not work well yet.   Do you have any advice for it?

Thanks,

Tayo

I checked the schematic for CYW920721B2EVK-02. The LED1 and LED2 use P27 and P26. 

Could you try to change it as follows:

/*! pin for LED 1 */
#define WICED_GPIO_PIN_LED_1 WICED_P27
/*! pin for LED 2 */
#define WICED_GPIO_PIN_LED_2 WICED_P26

Hello Zhang-san

I thought the same as you, and already attempted it. However, the LED did not work yet.

Now I'm checking source codes of Audio_Headset_and_Speaker" app. There is following code in headset_control.c

=========

#ifndef PLATFORM_LED_DISABLED
/*LED config for app status indication */

static wiced_led_config_t led_config =
{
.led = PLATFORM_LED_1,
.bright = 50,
};
#endif

==============

Under my environment, above codes seems disable. Maybe PLATFORM_LED_DISABLED is defined somewhere, I guess.  Do you think if the code relates the LED2 issue?

Thanks,

Tayo

I tested the hal_gpio demo on CYW920721B2EVK-02. The LED can work successfully on P26 and P27. So this should not be a hardware issue. I checked the Audio_Headset_and_Speaker demo, the LED2 is not used.

What do you mean "LED2 can't work well"? Did you add the related code to control LED2?

Hello Zhang-san

I also see that LED2 works using hal_gpio.  But in the case of Audio_Headset_and_Speaker app, it does not work yet.

The LED I mentioned is the following LED which is described in headset_control.c

==============

* Setting up Connection
* 1. press and hold the SW15 on BT board for at least 2 seconds.
* 2. This will set device in discovery mode(A2DP,HFP and BLE) and LED will start blinking.

==============

It's my understanding that the LED is LED2(D2) on CYW920721B2EVK-02. Is it wrong? 

 

Thanks,

Tayo

Hello Zhang-san

Our request is very simple.

Please tell me the way to work LED on  CYW920721B2EVK-02 EVB when Audio_Headset_and_Speaker app is running.

Thanks,

Tayo

I am using the following button configure. When I long press the CUSTOM button on the AUDIO board, I can see the LED2(D2) blinking.

/*! pin for LED 1 */
#define WICED_GPIO_PIN_LED_1 WICED_P26
/*! pin for LED 2 */
#define WICED_GPIO_PIN_LED_2 WICED_P27

#define WICED_PUART_TXD WICED_P32
#define WICED_PUART_RXD WICED_P33

///*! pin for LED 1 */
//#define WICED_GPIO_PIN_LED_1 WICED_P25
///*! pin for LED 2 */
//#define WICED_GPIO_PIN_LED_2 WICED_P29
//
//#define WICED_PUART_TXD WICED_P32
//#define WICED_PUART_RXD WICED_P37

//#define WICED_BUTTON1 (WICED_P00)
//#define WICED_BUTTON2 (WICED_P38)
//#define WICED_BUTTON3 (WICED_P34)
//#define WICED_BUTTON4 (WICED_P17)
//#define WICED_RESET_PIN WICED_P21
#define WICED_BUTTON1 (WICED_P05)
#define WICED_BUTTON2 (WICED_P14)
#define WICED_BUTTON3 (WICED_P04)
#define WICED_BUTTON4 (WICED_P00)
#define WICED_RESET_PIN WICED_P33

To avoid the codec drive error during the initiate process, you also need to change the SPI interface for the codec in the cycfg_pins.c and cycfg_pins.h file as follows:
