Hello,

I'm user of 'CYW20706'.
I will use the Bluetooth Module of CYBT-343026-01.
I read  blog 'Configuring the Bluetooth device address in CYW20706'.
https://community.cypress.com/community/wiced-studio-blueooth/wiced-studio-bluetooth-forums/blog/2018/01/24/configuring-the-bluetooth-device-address-in-cyw20706

'Company' is written in this document .
Which is 'Company', Cypress or user?

If user is answer, Do I have to write the DB_address in our production?

Best & Regards,

I have created a device that takes data generated and returns it to the PC.  The data has a numbered sequence in it to allow us to know if we have data loss.  Sometimes the device works well not dropping any data for long lengths of time.  Other times it will dribble data, this is with the same hardware and same PC and App.  Can you offer any advise as to how to get the data drop to cease?

Hello,

I have a custom PCB that uses the CYUSB3302-68LTXC hub and follows the circuit specified in this app note: http://www.cypress.com/file/139481/download

My schematic is attached.  The EEPROM (which was changed to a 24LC02) is pre-programmed with an image generated by the HX3 Blaster Plus tool.  All the settings are default except for the polarity swap on the US D+/D- pins. 

The problem is that I don't receive any indication that the PC recognizes the hub.  Nothing shows up in Device Manager on my Windows 7 machine.  I also tried a different Windows 10 machine and received an error that the USB device failed to reset.  The suspend LED is turned off and the DS power switch is enabled is enabled so I assume that something is working.  I've also verified that the hub is reading the configuration from the EEPROM correctly. 

Any suggestions would be appreciated. 

Hello,

I have a question:

why in CyUSB.dll you have to pass Byte array instead of OVERLAP struct

when call BeginDataXfer and/or FinishDataXfer ?

This increase complexity in develop program ...

Hello,

I have tried to download the program using olimex debugger.

It is working good in wicedSDK 3.7,but when I have moved my application from 3.7 to 6.2 latest sdk ,it is not working.

below error message showing.

Please help me regarding this.

Your help will be appreciated.

Hi, I have CYBLE-224110-EVAL EZ-BLE™ PSoC XT/XR Evaluation Board. As per the website "http://www.cypress.com/documentation/development-kitsboards/cyble-224110-eval-ez-ble-psoc-xtxr-evaluation-board", this device can programmed and debugged as a standalone device. Just wondering, are there example codes for this device to be used for standalone usage?

I have CY8CKIT-002 to program and debug, I do not have CY8CKIT-042-BLE.

Hi there,

We are having issues with bluetooth advertisement. To preface, we are using single core (cm0+) for Bluetooth, and have registered a callback function for the AppHost using Cy_BLE_RegisterAppHostCallBack() which Processes Events. As suggested in this discussion, Ble connection stops working after 'Max num. of ble connections' times , we have modified the cy_ble_hal_int.c file so that the callback is called during certain events.

Bluetooth can start advertisement, time out, restart, and so on successfully as long as no device has ever been connected. However, after the first connection proceeded by the first disconnection, once advertising times out it fails to restart again. We can confirm it as an issue with the device entering deep sleep while bluetooth is advertising since the issue doesn't occur when we put it into sleep mode instead. Our low-power code is as follows:

for(;;)

{

     if(!Cy_SysPm_Cm0IsLowPower())

    {

        Cy_SysPm_EnterLowPowerMode();

    }

    cy_en_ble_bless_state_t bleSsState = Cy_BLE_StackGetBleSsState();

    if(bleSsState == CY_BLE_BLESS_STATE_ACTIVE || bleSsState == CY_BLE_BLESS_STATE_ECO_STABLE)

    {

        cy_en_syspm_status_t apiResult = Cy_SysPm_Sleep(CY_SYSPM_WAIT_FOR_INTERRUPT);

    }

    else

    {       

        cy_en_syspm_status_t apiResult = Cy_SysPm_DeepSleep(CY_SYSPM_WAIT_FOR_INTERRUPT);

    }   

}

We are wondering what is the problem? Also, what is the best way to debug and stress test functionalities with deep sleep? In debugger mode, the described problem does not occur because the device does not enter deep sleep as it would during regular programming. Thank you.

I have several questions regarding the PWM module:

1. What does the PWM_Stop() do to the line output?

2. What does PWM_Start() do if i yet to configure the PWM_WriteCompare(value)?

thnaks!
