Hi,

我比较了一下CYW920719B2Q40EVB-01和CYBT-483039-02上面的蓝牙天线电路：

CYW920719B2Q40EVB-01如下图：

CYBT-483039-02如下图：

滤波器LFB182G45CL3D178是50欧姆阻抗，贴片天线ALA321C3也50欧姆阻抗，CYW20719B2也是50欧姆阻抗。

请问：如下图所示电路是不是可以直接使用？

谢谢！

Hello,

The data sheet for CYBT-353027-02 states that XRES has an internal resistance.

Please tell me this resistance value.

Best regards,

I have an IoT project for a client where I need to connect to a phone as a BLE peripheral.  While connected to the phone over BLE, I need to scan for a new connection to a Bluetooth Classic device, connect, and communicate with this device.  Do any Cypress dual-mode Bluetooth modules support simultaneous BLE and Bluetooth Classic connections?

Thanks!

Step by step, according to AN91445 (Antenna Design and RF Layout Guidelines),I used HFSS to simulate the S11 parameters of MIFA antenna.The simulation results are very different from those in Figure 17.
The.brd files of MIFA for a FR4 PCB with 1.6-mm thickness are provided in the AN91445.zip file.Even when the PCB thickness (1.0-1.6mm), ground plane area (20 mm × 20 mm to 50 mm × 50 mm, Based Figure25) and L_tip, L_leg length,(Based Table3 )are adjusted as required,Results similar to Figure17 were not obtained (the best S11 data was about  -5dB).COuld you provide specific PCB critical values and simulation parameters for the results in Figure17 ?

Hello,

I am looking into CYW20704A2.

1. What is the difference between CYW20704 and CYW20706. Can you please share link for datasheet/specifications for CYW20704A2.
2. For certification related do I need to search as BCM20704 or CYW20704.
3. For CYW20704 I am seeing only controller subsystem with QDID 159590 but not Host subsystem. If WICED is the support stack then what is the Host subsystem QDID.

Thanks & Regards

我们有个蓝牙的应用：蓝牙可以与多个其他蓝牙设备建立链接，然后需要传输文件（文件的数据量比较大）。

1. 请问这个功能的话，适用哪个蓝牙协议？

2. 最多支持多少个文件？

3. 最多能支持多大数据的传输？

您好，

请问Modus Toolbox 中如何设置CYW20719B2的Quad SPI接口？

我利用下图方法

打开了wiced_btsdk下的design.modus文件，并配置了SPI1为Quad SPI接口

SPI1工作于Slave方式。但是实际运行发现只有MOSI起作用，也就是工作于1bit方式。

请问Quad SPI该如何配置？

谢谢
