Hi everyone Regarding the Taiwanese NCC certificate, I think it is necessary to print the NCC mark + authorization number on the module. How should we assume the image of the component switching time of this module? Thanks Yang Show Less

Hi,

At the time of shipment, what BD address is already written in CYBT343026?

Is it possible to write a custom BD address before the shipment?

 Thanks,

Hi,

The manufacturing test tool "mbt.exe" is a Windows platform application.

We need to handle the test from non Windows platform. So please tell us the way to the test without mbt tool.

Hello,

I am evaluating the CYBT343026 module and  have a question.

I tried to send I2S data using BLE notification, but I2S data is unable to get from application, so I'm trying it without application.

Is it possible to send I2S data directly to BLE payload without going though the application such as HFP profile of Bluetooth classic?

Hi,

I have a question about "user_data" parameter in interrupt handler.
In the prototype of wiced_hal_gpio_register_pin_for_interrupt() API, 3'rd param(void *userdata) is "Will be passed back to userfn as-is". However, when I test it with following test code, it looks not working. I guessed "udata" must be printed out "123" but printed out "168". I am not sure if my test code is incorrect or it's SDK bug.

Q) May I ask what's wrong with following test code?

H/W : CYW920706WCDEVAL

S/W : WICED SDK 6.4.0 

 

void headset_set_input_interrupt(void)
{
          uint8_t my_data = 123;

          wiced_hal_gpio_register_pin_for_interrupt( WICED_GPIO_BUTTON, headset_interrupt_handler, (void *)&my_data );
          wiced_hal_gpio_configure_pin( WICED_GPIO_BUTTON, WICED_GPIO_BUTTON_SETTINGS( GPIO_EN_INT_BOTH_EDGE ), WICED_GPIO_BUTTON_DEFAULT_STATE );
}

void headset_interrupt_handler( void *user_data, uint8_t value )
{
        WICED_BT_TRACE("[%s] enter...\n", __FUNCTION__);

        if ( wiced_hal_gpio_get_pin_input_status(WICED_GPIO_BUTTON) == BUTTON_PRESSED )
        {
                 WICED_BT_TRACE( "Button pressed\n");
         }
        else
        {
                uint8_t udata = (uint8_t *)user_data;

                WICED_BT_TRACE( "Button released\n" );
                WICED_BT_TRACE( "udata = %d\n", udata);
      }
}

Thanks,

Hello All,

     I was trying to implement a new use case in which audio data has to be processed by codec DSP. so with SPI  I am trying to read audio data from codec memory region. But here I am facing one issue that is I am unable to find API's to give audio data packets. I am using latest-v3.x wiced_btsdk. In available sdk I2S is configured to route audio data but how audio data is handling in I2S interrupt handler and transferring to BT controller code is hidden it seems. so can anyone help me How Audio data is routing to BT stack. Even in playback case also I am unable to understand How Audio data is SBC (or) any codec  standard decoded and sent to codec.

Thanks in Advance.

i used the API of "wiced_hal_write_nvram" for write to nvram about 132byte.

but, sometimes it is fail with 0x004 error code.

my code is as below.

 

bytes_written = wiced_hal_write_nvram( 0x01, sizeof(setting_t), setting, &result);

 

and if i use the API "wiced_hal_write_nvram" for write to nvram, result is repeat as below.

 

save_setting(result: 4, written: 0)

save_setting(result: 0, written: 132)

 

where is the result of API of "wiced_hal_write_nvram"?

i want to know what is mean the result is 4. could you help me?

Hello!
I'm new to bT domain and I'm based in France & would like some assistance to choose the perfect Cypress module for my application.

 

My use case: BT Audio Earphones (HFP, A2DP, AVRCP & SPP together) , HFP slave initiating BT- reconnection incase of disconnection + Custom data commands 1) under HFP 2) under RFCOMM 
My custom commands are to interface with another Encrypted BT HFP AG device as Walkie - Talkie. 

My previous setup: WT32-IA under IWARP I'm able to achieve these above functions using the "ECHO" Command on IWARP API. now I'm planning to upgrade it to BT 5.0 specs & I'm looking to change to cypress. 

Please suggest which product is best for my purpose & especially can I achieve the Custom data command + HFP reconnection? Also suggest me which cypress chip should I go for ? 

Thanks for your input
