Dear Yatheesh,

Sorry to bother you again.

After the last /RD signal problem was solved, no more underrun error.

But recently, all system combined test, I received error "No error : 18" from CY3014 uart port ,then, Xfer to FPGA failed.

Please kindly advise what is "No error : 18" ?

Hi 

I am use CYW20706A2. and I want to connect special central device(BLE)

special central device prefer use LE 2M. 

so it send LL_PHY_REQ after device connected. But CYW20706A2 don't send LL_PHY_RSP

(my SDK is wiced studio6.4 and modus2.2(BTSDK2.8))

According to "BT Core Doccument",  if device receive LL_PDU_REQ, device have to send LL_PDU_RSP

But CYW20706A2 don't send it and LE data packet for connection. 

so device is disconnected.  why don't send LL_PHY_RSP on CYW20706A2??

I am using BLE CY8C4248LQI-BL583....

Along with BLE I use 2 nos. of UART ports.

I am unable to read UART_1_GetChar() for controlling my embedded design.

PutChar() is working fine...

When I check for any input char it recognizes. But when I write:

char ch;

ch = UART_1_GetChar(); 

ch does not get the value read by me... I tried all set ups of setting RX and TX in the design module....

Can you help me?

I've got some code I've been writing that I now want to convert over to be able to upgrade Over The Air.

The code has the BLE component set up as a Client and Server profile.  The Client profile is configured with a Current Time Service, to enable syncing of the time in my code whenever it is accessed via a central device.  In the Server profile, I've got various custom services along with all the normal ones (Device Information, Generic Attribute, Generic Access, etc).

The Server profile is also set up to stuff some data into the Scan Response Packet, to make it easier to get data across to the Client without requiring a connection.  Connection is reserved for firmware updates (if I can get this to work!)

The code, as a non-OTA arrangement, compiles and works fine.  Until I attempt to convert it over to an OTA Fixed Stack Bootloadable version.  I've done this before, just not with the CTS functionality included, and its always worked.  I've followed all the steps outlined in the OTA Guide (AN97060), but I'm still not getting the Bootloadable code to compile.  Its throwing up a bunch of errors associated with the CTS functionality, even though I've made sure I've included the appropriate header files, etc.

The particular things its getting errors on are:

• CyBle_GetClientState()
• CYBLE_CLIENT_STATE_DISCOVERED
• cyBle_ctsc

I can see that these are all defined in the Bootloader source code (in BLE_eventHandler.h & BLE_cts.c and BLE_cts.h), but for whatever reason, my Bootloadable code isn't seeing them.

Any ideas what I'm doing wrong??

Cheers,

I'm attempting to read the current time, and the local time info, from the CTS of an iOS device everytime I connect to the iOS device (I then use this to update the time in a RTC IC on my hardware).

I'm having success reading the Current Time information, but not the Local Time Info.

I'm following a similar process for both sets of info, but only the Current Time info is coming through OK.

In my main loop, I make the following calls to read the two sets of info:

CyBle_CtscGetCharacteristicValue(cyBle_connHandle, CYBLE_CTS_CURRENT_TIME);

CyBle_CtscGetCharacteristicValue(cyBle_connHandle, CYBLE_CTS_LOCAL_TIME_INFO);

For the call to get the Current Time, it correctly returns the CYBLE_ERROR_OK result.  But for the call to get the Local Time info, it seems to be returning CYBLE_ERROR_INVALID_OPERATION, and I can't work out what I'm doing wrong.

Can anyone

Hi,

FX2LP control endpoint 0 is able to transfer more than 64 bytes. How that could be explained?. The control center device info shows 64 bytes for the control endpoint 0. Is it the hardware versus software limitation?.

你好，我用Bus Hound软件（或其他工具测试遇到一样的问题）测试接收cx3 hid数据。当数据量频率不大时（数据包都是一样大小，64个字节），接收数据都正常，可以测试一天一夜。但是当发送的数据频率增大时，cx3这边很容报错：CY_U3P_USB_EVENT_EP_UNDERRUN，此错误的解释是：Indicates that a data underrun error has been detected on one of the USB endpoints. The event data will provide the endpoint number. 当高频率发送hid数据出现此错误后，即使复位hid，也无法恢复正常。复位hid如：

if (glIsHIDApplnActive)
{
CyFxUsbHidApplnStop();
}
CyFxUsbHidApplnStart();

请问如何解决cx3这种高频率发送hid报错问题？

瞬時停電（時間にすると数ns）が発生した場合の挙動について下記2点について教えてください。

　〇瞬時停電直後から一定時間が経過してから、通常パワーオン時と同じ挙動に復帰と考えて良いか。

　〇復帰にどのくらいの時間がかかるか。

　　　（例えばデータシート17.2項の図17.2において、リセット解除後にはｔRH（＝50ns）で復帰しています。

　　　　これと同等と考えてよいのか、または全く違った数値になるか）

以上宜しくお願い致します。

上記について具体的な数値があればベストですが、無ければ多少でも参考にできるような資料または情報をいただけると助かります。
