Hi everyone

Could you please tell me about the output setting values and

measurement conditions of "class 2 GFSK Tx power".

Thanks

Hi members,

I am new to this community and Cypress module. Looking for a starting guide to create my first project to send and receive commands from a host mcu.

Hello,

We are integrating a CYBT-333032-33 Module onto an MSP430 Design.  Can I get the confirmation that these pins (disregard Column 3, that is internal for us) are appropriate for EZ Serial Interface and Control?  

Also, on initialization I can expect the Initialization burst message to come in on the UART_TXD line/pad per the EZ-Serial Spec.  At 115.2K.  This is our confirmation of a functional interface and we will first check it on a scope.

Regards,

Hi:

     I had a problem using Mesh Client Control + mesh_provision_client:HCI communication failed! It was tested many times, but only once was successful! What should I do​?Thanks!

Hi,

When i build any project, i will get the tool chain error

I have "arm-none-eabi-gcc.exe have been forced stop"

CDT Build Console will show as following:

"C:\\WICED-Studio-6.4\\20719-B1_Bluetooth\\make.exe" wiced_bt_class.L1_HCI-CYW920719Q40EVB_01 download

Compiling wiced_platform_pin_config.c

Compiling wiced_platform.c

This application has requested the Runtime to terminate it in an unusual way.

Please contact the application's support team for more information.

Note: I run WICED IDE in Power-User mode.

Hi everyone

Could you please provide below information for us?

1, Errata information,

2, IBIS model,

3, 3D CAD data (Intermediate file: STEP)

Thanks

Hi everyone

From the QR code printed on the shield case of the BT module,

I think that I can confirm the serial number of the product.

Is there another way to check the serial number?

For example, is it stored in the memory of the BT module and can it be read via UART?

Thanks

For some reason I have to connect CYBT-423028-EVAL HCI UART to a USB2TTY board which has NO CTS and RTS pin.

In one document of CYBT-423028-02, I see below description:

HCI UART Connections

The recommendations in this section apply to the HCI UART (Solder Pads 3, 4, 5, and 6). For full UART functionality, all UART signals must be connected to the Host device. If full UART functionality is not being used, and only UART RXD and TXD are desired or capable, then the following connection considerations should be followed for UART RTS and CTS:

■ UART RTS: Can be left floating, pulled low, or pulled high. RTS is not critical for initial firmware uploading at power on.

■ UART CTS: Must be pulled low to bypass flow control and to ensure that continuous data transfers are made from the host to the module.

Then I left RTS floating, and connect CTS to GND of USB2TTY board.

It turns out that I can not initialize the CYBT to work. But with a full UART it can work, so it should be a CTS/RTS issue.

Here's my setting:

RPi <===> cp2102 USB2TTY bridge board <===> tx/rx/GND 3 wire <===> BT board External HCI (J1)

Is there any way to make it work with only RXD/TXD?

Hi,

Would anyone please suggest how to implement broadcasting light dimming values using lightness client on CYW20706. I have gone through dimmer demo application written for modbus using level client and server. Kindly clarify the below points to understand better the code.

1. Is it possible to use lightness client to implement dimmer switch? If yes, what are the API functions to broadcast message to other server nodes, consider provisioning through mobile app.

2. In WICED 6.2, I could find wiced_bt_mesh_model_level_client_send_set is the only API function available in level client to send message not wiced_bt_mesh_model_level_client_set as in dimmer switch demo. What is the p_event argument value for wiced_bt_mesh_model_level_client_send_set in level client, which acts as gateway or switch, to send messages to other server nodes, consider provisioning through mobile app.

A brief about my project, I plan to implement smart street light solution using one client, which act as gateway, to broadcast dimming value to other lightness server node. Please suggest if you have any better sloution.

Hi everyone

Regarding setting method of Tx_Power value of BLE / BDR / EDR.

If we refer to the following site and set Tx_pwer (as datasheet), then we can get below output value.

Configuring Transmit (Tx) Power on CYW20706 Chip - KBA228573

Is the below understanding correct?

BDR / EDR + 12dBm setting → BDR + 12dBm (typ) / EDR + 9dBm (typ) (Can get the output)

BLE + 8dBm setting → BLE + 9dBm (max) (Can get the output)

BTW, check the following information.
