Hi,

I'm testing HCI uart function which recieve data command. When test use "19 01 01 02 00 01 01"(scan) command. It is fine( Debug trace shown hci_control_process_rx_cmd : Data Length '6). But when I test data which is not done as WICED HCI UART Control Protocol, use "00 01 01 33 55 65", "hci_control_process_rx_cmd : Data Length"  debug trace not shown. And after that I use nomarl command ""19 01 01 02 00 01 01"(scan)", debug trace still not shown and I tried many times. No this trace come even I input normal format command.

1. Debug trace shown the len is not calculated 19 byte. Right? Because I input 7 bytes command(19 01 01 02 00 01 01), and this log shown len is 6.

2. I test abnormal command because I worried that there will be useless data been received by this uart. And I want this uart still can work normal, still can recieve data. But unfortunatelly, it works not fine. And even I send normal format command, it still cannot receive data(Because no debug trace shown). How to fix this problem? Attach is my code. Please have a check

Hello,

Pad pitch is defined in the datasheets of CYBT-343026-01 and CYBT-353027-02.

- CYBT-343026-01

       Datasheet: https://www.cypress.com/file/381006/download

       Page.6: Table 2 [Pad Pitch] 1.22mm

- CYBT-353027-02

       Datasheet: https://www.cypress.com/file/416356/download

       Page.6: Table 2 [Pad Pitch] 1.05mm

However, in [Table 3. Module Solder Pad Location] of each data sheet, the pitch of the following pad is different from the value defined above.

- CYBT-343026-01

       Page.8: Table 3. Module Solder Pad Location

              Pad 7 - Pad 6 = 12.35mm - 11.14mm = 1.21mm

              Pad 18 - Pad 19 = 12.35mm - 11.14mm = 1.21mm

- CYBT-353027-02

       Page.8: Table 3. Module Solder Pad Location

              Pad 8 - Pad 7 = 1.88mm - 0.82mm = 1.06mm

Is this a problem?

When designing a solder pad, should I design it according to [Table 3. Module Solder Pad Location]?

Hello,

Learning EZ-BT MESH Evaluation Kit with "Getting Started with Bluetooth Mesh" (AN227069) document I've met problem with application settings.

According to the p. 13 of the document, one can access application settings by rignt-clicking on the application name and selecting "Change Application Settings" .

Then the following window should open:

Probably this App. Note is based on an ancient version of ModusToolbox, because when I created application using template all the units that I see in the "Project Explorer" tab are project-type units but not application-type ones.

Consequently there is no "Change Application Settings" in the context menu when I right-click on project name.

Any ideas ?

Thanks.

Hello,

I am searching for a command string (hex) which I can send to the CYBT-343026 via serial interface for resetting the module to factory default settings.

We have several module in the field and the Uart-Interface is the only way to get access to the module.

Thanks a lot!

Best regards,

Hi,

I want to realize a function that HCI uart receive define string command to do related operation. For example, HCI uart receive "scan" command, then device will call the wiced_bt_ble_scan( BTM_BLE_SCAN_TYPE_HIGH_DUTY, WICED_TRUE, ibeacon_client_scan_result_cback ); API. Can this function be available? Because I see the example of HCI uart, it recieve and done HCI command(which have 5 byte head command). If I don't want to use HCI command, just use my defined string command, Is it ok? How to do this function?

Hi,

I'm testing OTA function with the ota_firmeare_upgrade example. But when I run Osotaupgrade.exe to do the upgrading, below fail comes. Please tell me why and how to modify code.

Hi,

I want to realize the function like WsOtaupgrade.exe tool. I have see the ota_firmware_upgrade example, I think this is OTA slavor part. How about OTA master part example?

项目以 CYW20706 为主控芯片，会用SPI 接外部flash, I2C 接 三轴传感器，ADC 读取外部电池电压，中断引脚会接到三轴传感器的中断引脚上。

现在有两个问题请教下：

1. 当CYW20706的中断 连接到 三轴传感器上的中断引脚。当 蓝牙模块 进入HIDOFF 模式时，是否任意的外部中断可以唤醒设备？还是只有特殊的引脚才能唤醒？

另外，怎么配置 蓝牙模块的 中断 是 高电平唤醒，还是低电平唤醒？

2. 能否在 使用SPI 的同时，同时使用HCI UART 进行debug 信息输出？API-REF-20706-A2_Bluetooth.pdf 文档中对于 HCI UART 的接口函数没有找到？有没有具体的文档描述？
