Hello. I purchased the CYBT-483039-02. I connected CYBT-483039-02 and USB-UART brige IC (FT231X). I attemped to program the CYBT-483039-02 using WICED Studio ver 6.4. I made new target "demo.hello_sensor-CYBT_483039_EVAL download UART=COM7". However, Download Failure occurred. The following error message was shown, "Download failed. This WICED platform of the SDK only supports download to 20719B1 device.".

What is the 20719B1 device? How can I  program the CYBT-483039-02??

Hello YuSa_4462546​,

CYBT-483039-02 is a BT-BLE Module having CYW20719 Cypress Silicon chip inside. We have some programming issues with CYW20719 based modules in WICED 6.4: BugS Report: WICED6.4.0/Missing files

I would suggest you to install WICED 6.2.1 and then use the module. We have several documentation available for your help:

Programming procedure:Programming an EZ-BT WICED Module – KBA223428

Thank you, Sheetalj_96. I installed WICED 6.2.1 and made target "demo.hello_sensor-CYBT_483039_EVAL download" according to KAB223747. But I can not program the CYBT-483039-02. Following messages are shown in console. Of course, I attempted the recover (CTS connect to low) and reset (XRES connect to low), but same error message are shown. How can I  program the CYBT-483039-02??

| No CYBT-483039-EVAL device detected.                                                     |

| 1. Verify the CYBT-483039-EVAL board is connected _AND_ powered                          |

| 2. Verify jumper J2 is populated                                                         |

| 3. Verify SW4 switches(CTS, RTS, RXD, TXD) are in ON position                            |

| 4. Press the reset button on the CYBT-483039-EVAL board and retry                        |

Please check if you are using HCI COM port for downloading and it is not open anywhere else. You can specify the COM port in Make Target as follows: demo.hello_sensor-CYBT_483039_EVAL download UART=COM23 where COM23 is the HCI UART port.

Also, check if you are recovering the board correctly: Press recover button, press reset button, release reset, release recover.

Thank you Sheetall_96. I checked my COM port from device manager. In "COM and LPT", there was only USB serial Port (COM4). HCI COM port was not shown. I installed  DP Inst_x64 in both wiced_uart and uart folder. I repeated uninstall and reinstall several times. But HCI COM port was not shown. How can I use HCI COM port?

1) Do update your Win10

2) Insert your EVK into the USB port of your PC. Avoid those USB hub.

3) Observe on your Device Manager and Ports, and wait a while

4) You will see two USB serial Ports if successful

5) If no, delete the USB serial port (com4)

6) Re-insert EVK and observe the USB serial port installation

Can you also ensure that the the jumpers (if available) for the two HCI ports are

installed properly?

If still fail, install the below from Cypress URL;

USB-Serial Windows Driver Installer – This file will install the Windows host drivers only. It is a windows driver archive executable that installs USB-CDC class driver for Virtual COM Port device (CDC-UART) and USB-Vendor Class driver for peripheral devices such as SPI, I2C, JTAG, GPIO, Vendor Mode UART and Manufacturing Interface.

Thank you BoonT_56. I attemped your answer 5 and 6. But I still can not find my WICED HCI UART and WICED Peripheral UART. I only find USB Serial Port (COM4). Is my CYBT-483039-02 broken? Is there a way to make sure it is working correctly?

It doesn't look like the FTDI chip is broken. Refering to the picture of the EVK, can you set all the switches on SW4 and 5 (circled in red) to OFF and then back to ON again? If failed, set all the switches on SW5 to OFF, and leave SW4 intact. Do a download.

Did you do those steps in my reply #6?

This eval board used a CY7C65215 to do the USB to serial conversion. Please re-install the windows driver for this IC given in the link in reply #6.
