Hi Team,
I am upgrading Wiced_2.3 library to wiced_6.6 library, I used BCM9WCDUSI09 platform folder in wiced_2.3 library however I could not find this folder in wiced_6.6 library, Which one should I use in Wiced_6.6 library ? Below is some information about chips and controller
WLAN_CHIP := 43362
WLAN_CHIP_REVISION := A2
WLAN_CHIP_FAMILY := 43362
HOST_MCU:= STM32F2xx
Please help me where should I look for same, It would be great help for me If you guys could help me as soon as possible.
Thanks

Hi,
I have to upgrade the code from Wiced 2.3 to Wiced 6.6 in which I used Platform BCM9WCDUSI09.
In platform BCM9WCDUSI09 for WLAN BCM43362A2 is used, which is not available in Wiced 6.6.
Can I used old platform i.e BCM9WCDUSI09 in Wiced 6.6 with lates WLAN firmware 5.90.230.38.
If yes then how should I proceed further.
What could cause the system to not recognize the proper drivers?
When connecting our PCB to a laptop, I do not see WICED JTag Port or WICED USB serial port.
I only get 2 generic USB Serial Port to appear (COM3, COM4):
I tried updating them using this thread/doc. , https://community.infineon.com/t5/Resource-Library/Upgrade-USB-Drivers-for-WICED-Studio-6-1/ta-p/246295, but still not getting those drivers to populate.
What could cause the system to not recognize the proper drivers?
Show LessI am using wiced sdk 6.6.0 and I want know is CYW/BCM 43362 chips supports WPA3 security type?
If yes then at which version of wiced sdk was added support of WPA3 and also wanted to know which WLAN firmware version support WPA3 support for CYW/BCM43362 chip?
Thanks

Show LessI am looking into speeding up the time it takes for my device to connect to an AP. A network packet capture is showing a delay of about 2.2 seconds between the active probe response from my AP, and the device sending the Authentication packet to start the connection process.
My device uses an STM32F412 MCU + CYW4343W Wi-Fi/BLE chip, and application is built using WICED Studio 6.6.1 with ThreadX/NetX Duo.
The application performs a Wi-Fi scan, finds the proper AP, updates the DCT with the appropriate channel, BSSID, security for the AP, and then calls wiced_network_up().
I have added debug to WICED, and narrowed down the delay inside of wwd_wifi_join_specific(). The delay is encompassed in the process of sending the JOIN command to the chip and waiting for it to finish –
Call to wwd_sdpcm_send_iovar( SDPCM_SET, buffer, 0, interface ) (where the buffer points to ext_join_params)...
to...
wwd_wifi_join_wait_for_complete( &join_semaphore, interface ) returning success.
I tried changing the parameters for dwell times (to very small values) and number of probes (to 1) in ext_join_params as they were set to use the default values, but this didn’t seem to change behavior.
I captured a network sniff from my Google Pixel of the same process and saw next to no delay between PROBE and AUTHENTICATE, so the delay doesn't seem to be required.
I don’t see where the PROBE to AUTHENTICATE is controlled anywhere in the WICED SDK, so I am assuming this is somehow baked into the chip/firmware?
Am I missing any type of configuration that would speed this up? Is there anything I can change in the SDK, or is this process controlled by the chip/firmware?
My network sniff can't see what is happening on all the channels. Is it possible that the process of traversing the channels during the active probe is the cause of the delay? Does anyone know if the channel traversal stops once it gets a probe response? In my case, the channel has either been 2 or 3. I can try changing this to a higher number to see if it changes the timing at all.
Show LessHi.
I am trying to use mbedtls library with TLS 1.3 support in WICED studio.
I am looking for the BESL supplicant library source code in order to check the transition from phase1 to phase2. Is that available somewhere?
Thanks

I am looking into speeding up the time it takes for my device to complete a 2-way TLS handshake. A network packet capture is showing that this process takes about 2.5 seconds to complete.
My device uses an STM32F412 MCU + CYW4343W Wi-Fi/BLE chip, and application is built using WICED Studio 6.6.1 with ThreadX/NetX Duo.
I realize that this is a computationally expensive process, so it might just be the way it is. However, I wasn't sure if there were any WICED build/config flags that might help speed this up.

Show LessHi
we designed a custom board that contains the wifi module: EWB-STERLING,(453-00014R )
In my board, I routing the USART1 pins to FTDI chip (FT4232 with 4 Channels).
I search all over the laird guides and no one mentioned how to program the board if I have custom board.
all the guides talk about the DVK and thats all.
my pc has recognized the FTDI with a generic name when I'm looking in the device manager(without the WICED NAME SIGNATURE).
I don't have any JTAG header( if its must I need to do redesign and I hope its not the case)
so how do I program the EWB module in the first time with USART1 through the FTDI?

WICED SDK 6.6.1.1
WLAN Firmware : wl0: Mar 31 2022 01:31:05 version 7.15.168.156 (4f1e919) (pulled from Modus)
I see references in the release notes and source code for WPA3-SAE. Is it supported?
What about WPA3-OWE / Wi-Fi Enhanced Open Mode? I did not see this directly referenced in the code but maybe it is handled on the WLAN driver side.
I assume WPA3-Enterprise is not supported.
