this post is an extensions of previous "Regarding a size of "audio_codec_buffer_size" when FOTA application is combined in audo_headset app" post.
I think it will be solved if I move some code to sflash area from sram.
However, I couldn't find a way to modify linker file for it and linker descriptor is generated automatically in CYW20706.
Is there any way to use memory resource as I want in CYW20706?Show Less
We have a BCM43340XKUBGT chip embedded on out product and need assistance on how to configure the setup to work with the cybluetool so that we can run certification testing on the product.
originally asked this question and the response was to sue cybluetool: https://community.cypress.com/t5/Wireless/BCM43340XKUBGT-Direct-test-mode-for-EN-300-328-certification-for/m-p/281066#M752
The issue that I am having is I have been unable to get a response from the device to the program. When using an oscilloscope to probe the UART lines I see the TX signal being sent from the PC to the chip but on the RX path I don't see any response form the chip.
I would like any more assistance that can be given on if there is any specific mode that I need to put the device into to get cybluetool to communicate and any hardware requirements. Is there a specific UART to USB cable that is known to work that I can check with.
From my side I am not sure if the issue is with the physical connection of the cables being soldered to the txd/rxd, if the chip needs a specific setup to enable the connection or if the uart to usb that I am using is not correct for this function. Any information that can be provided would be good.
We are promoting cyw920706 chip as subtitute of Nordic 52840 chip.
I heared that nordic they has limitation of the profile number to install.
Is Cypress has also the limitation of profile number?
Or, I wonder whether it depends on the chip models

Our Application is wired Intercom, and we have wires(audio connections) running between Central station to Extensions, and we would like to replace these audio connection wires with Bluetooth wireless connection, I am wondering if we can replace the wire by putting two Blue-tooth modules (CYBT-343026-01) one at the Central station and other at Extension point.
I am not really sure if that is feasible or not. Does these modules talk to only Host devices (like smart phone)?
can we establish wireless audio connection between two Bluetooth modules(CYBT-343026-01) without the help of any smartphone/any other host? Please let me know your thoughts about it.
I've combined FOTA application in Audio_Headset application and it's working as expected.
However, I need to reduce buffer size of ".audio_codec_buffer_size" in wiced_app_cfg.c to 0x2000 from 0x5000 to avoid reset during boot up. Otherwise, reset happened continuously.
I'm guessing this buffer could corrupt other RAM region and it caused reset problem. But, I think I need to keep the original size of 0x5000 for working of audio profiles like A2DP and HFP as you commented in "wiced_bt_audio.h"
So, How can I resolve this situation? I should reduce the buffer size if I combine FOTA functionality, on the other hand, I should keep the original buffer size for operation of audio profiles.
Could you please help here to solve this problem?
Where can I find a detailed memory map of the peripheral registers (0x40000000 - 0x5FFFFFFF region)?
feedback: it has been very frustrating navigating this SoC. Some basic information (like memory maps) are missing from the official documentation and we are left with the chore of digging the forum for nuggets of information that other vendors provide in the basic documentation.Show Less
I work for Viveris Technologies and we are interested in using your reference CYW20719 for one design.
Project context :
- Application : confidential, audio data transfer (full-duplex)
- Constraints : Operating temperature = -40°C/+85°C, low energy consumption (portable device)
- Development phase : Q4/2021 to Q4/2022
- Start of production : 2023 = 1K pcs
- Production : ramp-up to 10K pcs/year for at least 7 years
We have some questions about the Bluetooth stack:
1. How is it delivered, source code or compiled binary file ? Is it free of charge or is there any fees to pay for the BT stack ?
2. Can the Bluetooth stack be freely modified in order to :
- Remove the pairing over the air, add pairing through local MCU for security purposes
- Guarantee full duplex communication (talker/listener at the same time)
- Guarantee multi-profiles (HSP/HFP/A2DP emission, ADFP reception, SPP/AVRCP...) support with fast changes from a profile to another
3. What would be the impact of such modifications on the Bluetooth certification ?
Also we have an extra question about this component :
4. What is the maturity of this component ?
Do not hesitate to come back to us if your need more informations about these specific needs.

After i called function wiced_rtos_init_thread() several times successfully, each next call of this function fails.
It Returns with error code 0x10.
I call the function from exactly the same part of code, where i called it before.
Should this be caused by exceeding maximum size of stack?
And if so, where can I increase stack size?Show Less
I am using the MESH KIT, I connected one card to an PC. I use terminal to communicate with the device. My application is sensor client and temperature sensor server. The PC is connected to the sensor client card. From WICED HCI UART Control Protocol and hci_control_api.h I send this command to get temperature : 19 65 16 00 00
I get the response from the two seonsors : 19 81 16 11 00 1F 00 CD 65 00 00 00 FE F7 6D 3D 56 21 4F
00 01 2E 19 81 16 11 00 24 00 CD 65 00 00 00 FE F7 6D 3D 56 21 4F 00 01
I Want to know what mean each bytes to parse it in my application. Could you provide me help ?
My name is Daniel Lim
I tried to make demo with sample application 'Audio Sink".
I already succeded to make a sound with CYW920706CDEVAL kit.
But when I move sample application to CYBT-343026-01 EVAL workspace, updated library, modified target and
downloaded firmware by Modus IDE tool, I failed to make sound with Mobile
I found that GPIO pin can be multi functioned in guide document.
But I don't know how to configurate GPIO Pin to I2S pin.
It may be not tthat issue, But I have doubt of it.
please let me know how to make it sound with CYBT-343026-01
