Hello,

We are doing Bluetooth regulatory tests for our product with a CYW43353 chip. The CYW43353 datasheet says that it supports single frequency carrier-wave transmission. We would like to transmit on channel 38. Can we use hci commands to achieve it? I didn't find any vendor specific command for this feature.

Could you please give us some guidance on this? Thank you.

Dear Support Team

There isn't a Flash option in the below picture filter.  We were looking for a dual band WiFi SOC or a dual band WiFi&BLE combo SOC with  16MB Flash and supporting IPv6, and can be supplied by battery, and supporting keep sleep for sometime  and keep wake up for sometime. Could you please help to recommend us a part number for reference? Many thanks.

Hi,

I am using miniProg4 debugger with CYW20835M2EVB-01 EVK and studied attached file. But got error log "cannot read IDR". there is detail log as below. Any idea how to fix it?

As noted in another recent question:  https://community.infineon.com/t5/Bluetooth-SDK/a2dp-sink-cant-t-connect-to-20719-a2dp-source/td-p/330401 the Watch Example provided as reference code for A2DP implementation seems to have problems with the connection sequence, and it appears that the code does not actually perform to the Bluetooth Specification.  Can you explain the apparent deficiencies or provide examples of compliant code?  

As noted in the referenced post above, the connection sequence always seems to  fail for a previously paired device.  And we do not seem to be able to get SBC output to play on Airpods at all.

i am use cyw43455 as a ap on linux, i want to use wl util to config the cyw43455 as AP on 2.4G, but i see the channel config is fail, the channel is always "11", even i try to config as channel "1" or "6".   below is my wl command list

wl64s down
wl64s ap 1

wl64s wsec 0
wl64s wpa_auth 0

and the firmware version is as below

In my project, I also need a key Bluetooth, which requires HSM function. The specific requirements are as follows:

Certification requirements   :AEC-Q100

Bt Freq: 2.4G RF transceiver compatible with Bluetooth 5.0Low Energy

-40℃-105℃

1 SPI 

1 UART

>512K FLASH

3.3V

HSM.

Is there a suitable product recommendation？If not, is there a relevant product plan？ Thanks！

Hi,

Is the CYBT-413055-02 module supports for audio communication?

like HFP / HSP,  A2DP : Audio streaming, and AVRCP profiles.

I am not able to see the examples related to this profiles.

Thanks & Regards,

Srihari

Hi,

I want to convert my CYBT-4803056 module to EZ-serial but firmware as per knowledge base I downloaded the WICED_MOD_Prog_v1.5.19.102.zip but when opened I found it did not support CYBT-483056 board.

Please guide me how I can program this in CYBT-483056 board.

Thanks in advance.
