Studio Bluetooth Forum Discussions

Hi,

we are communicating data over BLE and would like to use the I2S for voice to a bluetooth headset or handsfree.

Is this possible with the EZ-serial firmware loaded ?

Thanks in advance

Purely from a part cost & power-consumption perspective. Is there a comparison of these three parts:

- CYW20706

- CYW20719

- CYW20735

For power, I'm mainly after

- deepsleep (wake on button)

- static/idle cpu+radio with wake on directed-advertise

- BT Classic TX @ +4dBm

thx David

hi!

for BLE we are using the CYBT-343026-01 with the Wiced EZ-serial firmware

1) can the EDR functions of the CYBT-343026-01 be used when the module is programmed with EZ-serial ?

2) is there a manual for the EDR setup and use of the CYBT-343026 ?

Thanks in advance

Hi,

I am using CYW920719Q40EVB-01 with revision 01. I am looking for external programmer support for this development board. In this forum, what i can found is not working for me.

I was following the below discussion thread

Cypress CYW920719Q40-B1 eval kit debugging

The schematic i can get from https://www.cypress.com/documentation/development-kitsboards/cyw920719q40evb-01-evaluation-kit  is belongs to board revision 2.1, where the board i have is revision 01.

Can anyone guide me the schematic for board revision 01?

I am also looking for how can i perform firmware upgrade  / flash firmware using J-LINK in this board?

Thank you.

Best regards.

Hey Internet,

I had previous success developing the CYBT-413034-EVAL EZ-BT module with WICED STUDIO V6.2.1. I recently decided to do a clean update to WICED STUDIO V6.4. I noticed that the CYBT-413034-EVAL platform seems to be natively supported in V6.4 meaning that I did not need to follow chaitanyav_41 document "WICED Studio: Platform Files for CYBT-413034-EVAL – KBA223746" to add the updated platfrom files as previosuly was required. So that is nice... But here is the issue. No matter what test snip that I try to make for the CYBT-413034-EVAL the board doesn't seem to run. For example if you attempt to make the target "snip.bt.spp-CYBT_413034_EVAL download" the program will compile, and even upload to the board and it will say in the Console that the application is running but the Bluetooth module does not broadcast the SPP TEST that it should.

After further testing it seems that none of the test snips for the CYBT-413034-EVAL seem to actually work in this new V6.4 WICED STUDIO version. They all seem to compile and upload to the board just fine but they don't seem to actually begin running.

Any help or pointing me in the right direction would be great.

I have since reinstalled WICED STUDIO V6.2.1 and I am back up an running in the meantime.

Thanks,

Martin

Hi team Cypress,

I'd like to understand how mature / well tested the code example for A2DP source is?

Code-Examples-BT-SDK-for-ModusToolbox/CYW920719B2Q40EVB-01/apps/demo/watch at master · cypresssemiconductorco/Code-Examp…

- Any products on the market that uses this bt audio source stack?

- Any lists of sinks that is supported? I've seen on other BT audio source products that they have issues with some newer BT headphones incl. apple Airpod 2's

Thanks David

Is there function or other mean after have conn_id to get from conn_id if this connection is BLE or classic?

Let say the example given in 002-23400_AN223400_Getting_Started_with_EZ-BT_WICED_Modules.pdf

where SPP and Hello_sensor are merged - how in the code can distinguish the type of bluetooth connection and at what stage, because at the beginning both processes are same?

Thanks

Hello Sir/Madam,

   We have designed our own customized PCB board using CYBT-423028-02 module. A screenshot of a schematic is attached here.

Development environment:

Windows 8.1 pro

Platform: CYBT-423028-02 (Module)

IDE: Wiced Studio 6.2.1

Hardware: Customized hardware board using CYBT-423028-02 module

Also followed the steps suggested in this link: WICED Studio: Platform Files for CYBT-423028-EVAL - KBA223637

We are facing to program a CYBT-423028-02 module using USB-UART bridge.

Please note we have followed the hardware setup and connection as suggested in below link.

Programming an EZ-BT WICED Module – KBA223428

And tried to load an application to the module, got the output in a console as attached here.
