hi

I am attempting to set the I2S interface in SLAVE mode for the Call Audio configuration.

So I have one doubt regarding this :

In slave mode do we need to set the WBS and I2SPCM sample rate and clock rate.

If yes then , As the clock will be provided from external source then why we need to set the clock and sample rate?

Thanks for your help

Hi - I am attempting to use the HCI UART method to change the BT device address per the Cypress Developer Community link below, and it appears that we have to add some code to our project in order to enable the HCI interface.  Although there are some HCI samples, they seem pretty specific (audio, HID, etc.) and all we need to do is add code that allows us to use the ClientControl.exe Windows app provided by Cypress to update the BT device address.  Although the ClientControl app can attach to the HCI COM port, it can't connect to the board so none of the functions in the ClientControl  app are enabled.

Hi,

I'm trying to configure one of the ACLK pins to provide a clock to an external device. I've tried adding the following lines but it does not appear to have any affect:

            wiced_hal_gpio_configure_pin(WICED_P36, GPIO_OUTPUT_ENABLE, 0);

            wiced_hal_aclk_enable(24000000, ACLK0, ACLK_FREQ_24_MHZ);

I could not find anything that explicitly tells the GPIO driver what function I want on the pin, how does it know I want ACLK0 on P36 (rather than P32).

Similar to this question but a different device: CYW20735 ACLK on pin

Thanks

Hello,

I have the CYW20719Q40EVB-01 board and am trying to conduct througput tests over BLE and BR/EDR between the board an a Sony Xperia XZ2 Compact (supporting Bluetooth 5). The problems I'm experiencing only regards BLE. When connecting to the device I'm setting the preffered PHY to LE_2M which returns SUCCESS but when I'm sending bigger chunks of data and calculate the throughput, it seems that the PDU-size has not been extended to enable 251 byte payloads. The carachteristics for transmitting data have been setup for 247 bytes.

Is there a way to increase the Link Layer RX/TX payload size in wiced studio?

Best regards

I have an application that requires one Bluetooth device to connect to 2 other devices simultaneously.

-- one for remote control data (small packets) connected to another embedded device

and

-- one inbound audio stream connected to a mobile phone

What development kit would you recommend?

Are there any example projects that fit this requirement?

Hi,

wow I'm here again!

Simple code that I've had working on ESP32 & DA14585...

Basically this is the code:

uint32_t commands_val;

commands_val = 0x11223344;

wiced_bt_gatt_send_notification(conn_id, HANDLE_COMMANDS_VAL, 4, (uint8_t*)commands_val);

This is received incorrectly on my test environment (MacOS). The other platforms - ESP32 and DA14585 respond correctly. A temporary work around is to read the handle again if the value is what is expected, this then reads the correct value 0x11223344.

Any suggestions?

Thanks.

Are there any documents about BT 6.0?

Thanks!

現在、CYW20719のサンプルコードをベースにJ-LinkにてDebugをしておりますが

Step実行で、Local変数が確認できない(optimized out)や

ソースコード上の移動が上から下でない場合等があります。

現在、Build設定がReleaseになっており、Optimized設定が高いために

そのような動作になっていると思われますが、Build設定をDebug設定にして

Optimized設定のlevelを下げる方法を教えていただけませんか？

具体的に教えていただけば、幸いです。
