Hi

Could you provide SIG Certification Report?
We want to conform it.

Thanks

As a follow on to this closed thread: CYW20719 - I2S Driver / APIs​

I was hoping that perhaps somebody could supply some information on how to access the I2S interface.  Specifically,  i am programming a CYW920719.   My application requires a DAC/CODEC but the sink data does NOT come from a BT Peer,  but rather the application itself.  Do I need the entire A2DP and an BT Peer simply to stream application produced data to a DAC/CODEC?

Dear Sirs and Madams!

Is it possible to get souce code of BCM20730 firmware, so I can customize my application?

Sincerely,

M.

Hi,

I want use 20706 to connect one master and more slavers.

And when I connected the third peripheral, directly return the connection down error. The disconn reason is 0x04.

I tried a variety of connection parameters ,but all of them didn't work.

Hi

Could you tell me the state of the following pins during reset?((Hi-Z state?)

16pin UART_TXD
17pin UART_CTS
18pin UART_RTS
20pin UART_RXD

Thanks

Hello,

Is it possible for the application to some how signal from the wiced_transport_data_handler_t [1] callback to the caller that the data can not be consumed at the moment?  In which case the caller would stop reading data from the UART HW which would cause the RTS to rise?

/** Wiced transport data handler

* Call back registered by the application to recieve data. Application has to free the

* buffer in which data is received. Use the API wiced_transport_free_buffer to free

* the rx buffer

*

* @param[in] p_data : Pointer to the received data buffer.

* @param[in] data_len : length of the data pointed to by p_data in bytes.

*

* @return the status in case of UART in HCI mode

*/

typedef uint32_t (*wiced_tranport_data_handler_t)( uint8_t* p_data, uint32_t data_len )

Does the 20719 support coexist with BT?

Is there a DEMO in WICED?

Tks!
