We test the WICED  6.2   and program the headset example into CYBT_343026_EVAL.  We read the source code of 20706 and see some HCI commands, could you explain how to use these commands? Or  could you give me some guide document  for vender specific hci command?

Thanks a lot.

Does the CYUSB4357 Hub support Selective Suspend between the USB2 and USB3 channels?  That is, are the active and suspend states of both USB2 and USB3 channels in the Hub treated together?   

Case: If the Hubs upstream USB3 link is inactive but the USB2 link is active, and the host decides to put the USB3 link to sleep, will the USB2 link in the Hub stay in an active mode, or will the Hub keep the USB3 link up because the USB2 link is active.  Visa-versa, if the Hubs upstream USB2 link is inactive and the USB3 link is active, and the host wants to put the USB2 link to sleep, will the USB3 link stay up, or will it also go into suspend mode, or will the Hub keep both links up because of the activity on the USB3 link?  

Finally,  I assume that if the Hub can treat the USB2 and USB3 link states separately, that it can also support putting the respective downstream ports to suspend state depending if the downstream ports are connected to USB2 or USB3 endpoints.  Is that correct?   

I am designing with the CY14V104NA-BA45XIT. I don't see any guidance in the datasheets of app notes about power sequencing. Is there any requirement for enabling and disabling VCC and VCCQ in relation to each other? 

Bluetooth connection to the Raspberry Pi

I am using a CY8CKIT-062-WiFi-BT with ModusToolbox and would like to transfer measurement data to the Raspberry pi.

The possibility from one KIT to another would not be bad either.

I can't find any suitable examples.

AnyCloud BLE Environmental Sending Service is very comprehensive and you cannot see how CySmart accepts the data. 2 bytes are transferred and then?

Must WICED modules still be used in the programs. I would like to use only "ModusToolbox" and its components.

Can one show me examples for the transfer of floating point values via BLE.

thanks

I work in a virtual computer environment and can therefore use the variables CY_TOOLS_PATHS: = C: /Infineon/Tools/ModusToolbox/tools_2.3 and CY_GETLIBS_CACHE_PATH: = C: /Users/user/.modustoolbox/cache do not set in windows.

I have set the PATH variable in the Makefile and in the IDE.

Now comes this error

Hi Community:

We are now use CYBT_343026_EVAL (WICED-SDK Version: Wiced_006.004.000.0061) working as a Dual-mode Bluetooth controller with LL Privacy enabled.

When doing the LE_Create_Connection with Own_Address_Type = 0x3(3, "RPA or Random Address") , the controller always HCI Command Complete Event with Status = 0xC (12, "Command Disallowed", "Command Disallowed"). 

Below is the HCI log:

We also did a simple test with Cybluetool :

Please support us do a kind check  on this issue?

Hi,

I playing with RX UART DMA based on CE224406 – PSoC 4 UART.

I want to have two 8 bytes RX buffers, which would be filled by DMA with data read by UART.

First thing i changed is data elements in transfer for both rx descriptors 0 and 1.

And everything works fine, after 8 keystrokes i got entered text back on my serial terminal. But it's done using the flag called txBufferIdx which points to currently used RX buffer. It's good, but when you skip one reading, everything would be out of sync.

So I try something like this

 for(;;)
    {
        /* Wait for complete transfer and check if it comes from RX DMA  */
        if(0u == (UART_RX_DMA_CHANNEL_MASK ^ CyDmaGetInterruptSourceMasked()))
        {
            /* Clears the rxDMA interrupt source */
            CyDmaClearInterruptSource(UART_RX_DMA_CHANNEL_MASK);
            
            // detect which descriptor should be used
            volatile uint32(descriptor0Stat) = UART_RX_DMA_GetDescriptorStatus(DESCR0);
            volatile uint32(descriptor1Stat) = UART_RX_DMA_GetDescriptorStatus(DESCR1);
            
            // it shoule be done to get data
            if ( (descriptor0Stat & CYDMA_RESPONSE ) == CYDMA_DONE )
            {
                /* Points transmit DMA to buffer which contains received data and enables transfer */
                UART_TX_DMA_SetSrcAddress(DESCR0, uartRxBuffer0);
                UART_TX_DMA_ValidateDescriptor(DESCR0);
                UART_TX_DMA_ChEnable();

            }else
            {
               // maybe another one is done
               if ( (descriptor1Stat & CYDMA_RESPONSE ) == CYDMA_DONE )
               {
                    /* Points transmit DMA to buffer which contains received data and enables transfer */
                    UART_TX_DMA_SetSrcAddress(DESCR0, uartRxBuffer1);
                    UART_TX_DMA_ValidateDescriptor(DESCR0);
                    UART_TX_DMA_ChEnable();
               }
            

            }   
        }
    }

I want to take decision which buffer should be send back based on DMA descriptors status' but after two first transfers the status got by UART_RX_DMA_GetDescriptorStatus is always 0x80010000 for both buffers.

What do i wrong?

Maybe another idea how to get info which is most recently filled buffer?

Thank you in advance

Kris
