Hi, @BragadeeshV
I couldn't answer the existing question, so please understand that I am inquiring with a new post.
Previous question : Solved: SRRC adaptivity test with CYW4343W(LBT,DAA) - Infineon Developer Community
I'd like to get final confirmation of the contents of the SRRC adaptivty application for CYW4343W.
I checked the DAA (FHSS) as you guided me before
I also checked the adaptive item below with DAA.
I'm sorry to bother you, but could you check if it's okay to proceed as it is?
Best Regards,
Show LessHi,
I'm starting to develop a custom bootloader which will be able to receive a firmware over uart and write it on flash. I've started from the tiny_bootloader provided in the wiced example and have integrated the sflash_write example and the uart driver.
For now I'm having issue during link, it does not find all variables which shall be provided by the linker: undefined reference to `link_aon_data_location' 'link_aon_data_end' 'link_ram_data_location'
See build output:

However those variables seems to be present in the map file in 43xxx_Wi-Fi\build\roomz.custom_bootloader-CYW943907AEVAL1F\binary\roomz.custom_bootloader-CYW943907AEVAL1F.map
Any idea why the linker does not find them?
Show LessWe are interested to use the CYW54591 in one of our designs and we would like to know if ModusToolbox support this Chipset, also we would like to know if we can route WIFI data to the UART or SPI bus through software.
Thank you for your time and help
Show LessHi,
I'm evaluating the WIFI/BLE module 1LV by Murata with a STM32H747-Dicovery board and Murata adapter as reported in the PDF file in https://github.com/Infineon/stm32-connectivity/tree/master/Documentation
The connection works fine (wifi scan OK and connection OK) and now I'm trying to increase the communication performance; the first test, using LWIP stack as server on MCU and ipref client on windows/linux side gave me only 0.15-0.20MB/s (150kBps) that seems to me very VERY slow using SDIO interface (with 25MHz clock).
Do anybody have any clues to increase this bitrate?
What can I change from the test project (https://github.com/Infineon/stm32-connectivity/tree/master/Projects/STM32H747I-DISCO/Applications/wifi_scan) to increase WIFI performance?
Do you also think that LWIP stack is the correct "library" to have good performance (at least 2.5-3.0MB/s)
Thanks
Show LessHi,
I am planning to integrate BCM43438A0 with AM3358 for our custom application. We are looking for the WL utility for FCC certification of the same.
Hi,
I have a one question about SRRC(China) certification test related to adaptivity test.
Recently, I heard SRRC also added adaptivity test like as CE.
For the test, it needs to be filled out the application form as below.
The question is which mechanism is used between LBT and DAA in CYW4343W? or need to be check both?
Best Regards,
Show LessWe are using version v5.10.9-2022_0511 in our new product. In older product we applied a patch with a fix for this CVE. Now we have new product with the mentioned version and wonder if the fix for CVE-2019-15126 is part of this release or patch is still required.
Show LessHi Sir,
Please provide tssi tool ubuntu version.
Thanks.

Hello everyone,
I'm customizing Android 6 to fit a SoC that comes with muRata LBEE5KL1DX (CYW4343W).
I successfully embedded Cypress Linux WiFi Driver Release (FMAC) [2022-03-31].
NVRAM file comes from muRata repository, firmware and clm_blob files come from the above archive.
If an access point uses (WPA2-PSK) either TKIP encryption only or its combination, Android sometime takes till 2~3 minutes sometime within few seconds to acquire a dynamic address and establish the connection.
If an access point uses (WPA2-PSK) AES encryption only, Android always connects it within few seconds.
I digged in calling kernel module in this way
insmod /system/lib/modules/brcmfmac.ko debug=0x00108414
but I didn't achieve good results.
Using TKIP encryption, the board sometime has to receive several dozen of DHCP offers before establish a connection. Using AES encryption, radio quickly connects 10/10 times. The same behaviour using different access points (Sitecom, Digicom, Netgear).
What you think about ?
Thanks in advance for whatever help and best regards.

Hi Infineon,
Is it possible to run AP(5GHz)+STA(5GHz) in RSDB mode on CYW54591? Can I set the different channel but both of chains are running in 5GHz band, I expect to use this condition to maximize the throughput while RSDB mode is enable.
Thanks and regards.
Frankie
