Studio Bluetooth Forum Discussions

Dear all,,,

Our application is using CYBT-343026-01 among Cypress BT modules.

The main module and Cypress BT module are connected in the form of a card cable,

and the function test has already been completed.

We are now conducting an ESD test at the system level, one of the reliability tests.

If 2kV is applied, the BLE module resets and ESD test fails.

When connecting the BT module to the main module of the system,

we need to advise for ESD protection and considerations for hardware design.

If you have an application note or any documents for that request, could you please provide us!

Thanks,

Best Regards,

PH

Please need information with delay or wait process time in module cybt-343026

In another module cy20719 sleep run in delay in  1000ms.

My module cybt-343026 not sleep mode.

Please help me.

Thanks

Hi,

I am following the "CYW920706WCDEVAL Kit Guide" to view the traces on the windows with Bluetooth application Hello Sensor

I had followed "4.4.2 View Traces Using a Terminal Emulation Program" with no problem.

However, When I tried to view the traces using the BTSpy (4.4.3 View Traces Using the BTSpy Windows Application), I could not see trace messages. The Client Control and BTSpy displayed these and no more:

16:45:43.762 Opened \\.\COM46 at speed: 3000000 flow on

16:45:45.753 Startup

16:45:45.753 Set discoverable:1, connectable:1

16:45:45.753 Set Pairable:1

The Bluetooth application is built and downloaded and works well.

Thanks

Hello,

"WICED-based EZ-BT Module" has obtained safety standards as follows.

- CYBT-213043-02 : EN 62368-1

   RF Regulatory Certifications for CYBT-243053-02 EZ-BT™ Module - KBA228230

- Other CYBT module : EN 60950-1

   RF Regulatory Certifications for CYBT-343026-01, CYBT-343029-01, CYBT-143038-01 and CYBT-343151-02 EZ-BT™ Modules - KBA2…

"EN 60950-1" will expire on December 20, 2020, so it is necessary to re-acquire "EN 62368-1".

[Question]

Q1. Does the module which acquired "EN 60950-1" re-acquire with "EN 62368-1"?

Q2. If Q1 is Yes, I use CYBT-343026-01, so I want to know when this module gets "EN 62368-1".

Best regards,

Hello,

Sorry if this is a stupid question. I need a virtual COM port between MCU UART and Bluetooth. Some competitors' products have a mode in which you can use the Bluetooth module as a peripheral device connected to an MCU.

The "CYBT-483039-02 EZ-BT™ XR WICED MODULE" has great specs and would be a strong alternative, but it is not clear if what I want can be done or how much work it would require.

I have looked at the below links:

https://community.cypress.com/docs/DOC-16170

Also, the user forum doesn't work properly with Firefox.

Thanks in advance

1. I am using CYBT-413034-EVAL.

2. I have tried programming CYBT-413034-02 present on CYBT-413034-EVAL. I powered up the board using external dc power supply of 3.3 V (by connecting to VDD and GND pins present on J3 connector). I did not connect the USB port of the eval board to the PC. I pushed all the switches of SW4 and SW5 to OFF position.

3. I connected TTL level signals of HCI UART (namely UART_RXD, UART_TXD, UART_CTS, UART_RTS present on header J1) to another board with RS232 transceiver present on it. The RS232 level signals were connected to the PC DB9 connector.

4. Please remember that I selected the following setting in WICED Module Programmer GUI 

CYBT-413034-02 for Module Name

UART Adapter Board for Programming Board

Baud rate as 115200 under DUT Serial Port Setting

CTS flow control is ticked under DUT Serial Port Setting

4. The log in 1.jpg shows this.

5. The log in 2.jpg shows after resetting and recovering the board.

Please help.  

Hi

The customer is trying to develop a small product and is currently struggling with module placement. They would be grateful for any advice on the placement.

Please let us check the 3 items.

1, According to 7.3 described in AN96841, it is described that there is a significant effect within 7mm in 7.3.1, but the minimum clearance of 5mm in 7.3.2.

If the distance to the resin part is 4mm, will it be noticeably affected? (They want to get a 1mm margin)

2,Is the recommended clearance for AN96841 7.3.2 from the module edge or the antenna pattern?

3,Does the module require resin and distance in the horizontal direction as well?

Please refer to the drawings for details.

Thanks

Are there any wiced functions that can use to write some custom (user defined data). Let say I want to write and read a simple uint8 in the AON memory?

Thanks

Hi Cypress,

Our customer is asking if WICED SDK supports for the API for "Security Request" of BT Spec 3.6.7?

Customer wants to request security from slave to master like as following BT Spec 2.4.6 Slave Security Request.

As you can see BT spec, slave device can request security by transmitting a Security Request command to master device. I am not sure if WICED SDK supports for API for this command. If so, could you let me know what's the API?

For your information,

- WICED SDK : 6.3.x

- Cypress chipset : CYW20721

Thanks,

Liam
