What are the risks or limitations of using CYW20719B1 based radios for development while waiting for stock of new CYW20719B2 radios to become available due to current production constraints?

There is current stock of the B1 based radios at several distributors.

Stock of B2 radios is currently limited.

CYBT-483039-02 for CYBT-483056-02 - Module size: 12.75 mm × 18.59 mm × 1.80 mm
CYBT-413034-02 for CYBT-413055-02 - Module size: 12.00 mm × 16.30 mm × 1.70 mm
CYBT-423028-02 for CYBT-423054-02 - Module size: 11.00 mm × 11.00 mm × 1.70 mm

CYBT-483039-02, CYBT-413034-02 and CYBT-423028-02 are based on CYW20719B1 silicon and supported in WICED
CYBT-483056-02, CYBT-413055-02 and CYBT-423054-02 are based on CYW20719B2 silicon and supported in ModusToolbox
QDIDs are different for each

Hi,

I'm using MTB to download/debug application for CYW920706 and MTB supports target programming in this tool itself.

It's a good process for me so far.

But, I think I need a standalone programming tool using USB/UART to check the state of HW functionality when I build a new board with CYW20706 chip.

Is there any standalone programming tool for this use case?

Thanks~ 

I tried to make a demo board with CYBT-343026-01 module

Actually My customer used a BM20(microchips) for the project at the moment.

They want to substitue other BT classic module because of the semiconductor shortage.

BT20 include a DAC module in it.

I wonder whether CYBT-343026-01 module has any benifit instead of BM20 or not?

If I promote CYBT-343026-01 module as substitute one. There should be some benefit in case that DAC module exist as separte module.

Many Thanks

Hi，there：

We are now using CYBT_343026_EVAL which is CYW20706 inside working as a Bluetooth Controller。Our custom board works as a Bluetooth Host。

We noticed that SCO Offload - voice data routing over I2S/PCM interface supported （WICED Bluetooth Software Features - Cypress Developer Community）

Is there any guide or sample to about enable offload mode in our case？

Hello good afternoon I would like to know the driver for development kit CYW920719B2Q40EVB-01

Hello good afternoon, I ask for help for the connectivity of a serial multiport using CYW920719B2Q40EVB-01

I am using Bluetooth Low Energy v2.5.2 in nRF Connect app for Desktop. With CY5677 CySmart BLE 4.2 USB Dongle plugged in, when I select device to connect, I receive an error message saying "Received status with code 0 PKT_SEND_MAX_REACHED, message: 'No response from device. Tried to send packet 6 times. Error occurred when opening port. Errorcode: NRF_ERROR_TIMEOUT (0xd)". I tried to uninstall and reinstall the app, reboot my PC, tried different USB ports, use different BLE app and make sure that the dongle is still working. Can you someone help me with this? Thank you so much

Is the CYBT-413055-02 module capable of being A2DP source and handling BLE events at the same time?

I have tested  this functionality on the CYW920719B2Q40EVB-01 board, which contains the same MCU (CYW201719B2) as the module. I used the audio watch example for this. However, the CYBT-413055-02 module doesn't have any audio examples. Is there any technical limitation that does not allow it to be used as an A2DP source device? Or should the examples made for CYW920719B2Q40EVB-01 work fine on the module as well?

I'm using the ModusToolbox 2.3.1.

Best regards,

Pista

There is a readily available RF Module using CYW20706. My application is a bluetooth microphone using bluetooth profile HSP, HFP, or A2DP. Is it possible to use the CYW20706 for this application?

If possible then please specify if it is possible to do it without an external MCU.

CYW20721 looks like it has what I need but I am having a hard time reading the datasheet. Please answer these questions for this chip:

1. Is the BT RF antenna built into the chip?
2. If no antenna then does there need to be an external filter or matching circuit in addition to the antenna?
3. Can this chip support HSP or HFP bluetooth profiles with the current firmware or custom firmware?
4. How can this chip be programmed, what is the recommended programming tool?
5. What is the recommended software development environment for this chip?
6. Does anyone offer modules with this chip?
