Wi-Fi Combo Forum Discussions
Hi,
As I'm checking OTA2 manual and some forum column but I'm not sure something so please tell me following parts.
HW platform; STM32F412 + CYW43438.
Q1: Can we use both of OTA and OTA2 for this HW combination.
I'm sure Yes but it is for double check.
Q2: According to OTA2 documents, it seems to show only "PUSH method" using SoftAP and Webserver in the WICED.
Is there any sample application to configure "PULL method" by OTA and/or OTA2 ?
e.g:
1.Assert GPIO
2. WICED try to download OTA2_Image from the internet like a webserver or FTP server.
3.Extract image in the WICED starting address.(I think this operation is handled by OTA2_extract)
PULL method is very popular in IoT application, such as white goods.
Thank you.

Show Lessi have stm32f407 discovery board which is same as a STM32f417..
also one EVB which is with CYW43455.. same as like LSR-LWB 4343 board.
i'm using LSR-lwb 4343 platform file and "CYW943455EVB_02" platform file for make my own platform file.
i want to platform file for this setup. can you help me pls.?
Show LessHi Sir,
We are currently developing a product that uses Raspberry Pi 3 B+, which uses CYW43455 as its BLE solution.
Now the product is being tested for certification; however, the RF test result showed that the E.I.R.P power is more than 10 dBm.
The certification organization suggests that the transmit power can be lower to pass the test.
Could you tell me how to adjust the Tx transmit power? preferably by hcitool if there's any vendor specific command.
Since we didn't implement the firmware by ourselves so we don't have any kit in hand.
However, we will definitely get one if changing the Tx power requires re-programming the device.
Thanks for your reply in advance.
Show LessHello everyone,
I'm currently working on the evaluation board (BCM943362WCD4_EVB).
I could see in the datasheet of the CYW43362 (datasheet attached) that this chip need a dedicated crystal or an external dedicated/shared TCXO. However, I can't see this link anywhere on the schematic of the BCM43362WCD4_EVB (schematic attached).
Moreover, the pinout of the WiFi transceiver displayed in the schematic is standard while the only packages available for those chips are WLBGA.
I'm looking forward for your responses.
Regards, Christophe
Show LessIs the CYW43907 capable of generating the 50MHz reference clock for RMII interface?
Hi,
I'm designing STM32+CYW43438 module with WICED.(WICED ver is Wiced_006.002.001.0002).
I'd like to know following points.
1. In default, where is clm_blob stored ?
2. When I added countries to my regulation and made clm_blob via Mycase ,
how can I program to my module ?
<Back Ground>
Usually, I used host based IC ,such as CYW4373 or CYW43455 with Linux.
In this system, we changed clm_blob binary itself in my Linux but I'm not familiar with WICED so I don't understand basic point as above.
I hope to get anyone help.
Thank you.

Show LessHi all,
i want to port the a2dp(audio) code from one wiced target to another wiced target(43xx_wifi).There is no a2dp(audio) profile code for BCM94343WWD2_EVB in SDK.
I have seen a "bluetooth audio example" in 43xx_wifi SDK, So ,is it possible to port "bluetooth audio example" code for BCM94343WWD2_EVB platform?
Please provide any suggestions for porting a2dp profile on BCM94343WWD2_EVB platform.
thanks.
Show Lesswiced_framework_set_boot with parameter WICED_FRAMEWORK_LOAD_ONCE will cause CYW43907 hang up!.
I tested with application demo: snip.tftp.
If I use WICED_FRAMEWORK_LOAD_ONCE for wiced_framework_set_boot, CYW43907 could startup normally next time.
But it will hang up if I power off then power on next time.
I can produce this issue 100% times. And my SDK is WICED-Studio-6.2.
Is this could be an issue? I'd like to use WICED_FRAMEWORK_LOAD_ONCE when update system's application..
Show LessWICED SDK don't implement DHCP Decline msg.
So if IP have been used by a device, will cause other devices can't get correct IP.
Typical scenario:
DHCP server startup. First dhcp client device startup and get IP *.*.*.2.
Then DHCP server restart, due to first dhcp client device have startup and get IP, it will don't send dhcp request again,
and DHCP server don't known *.*.*.2 have been used(WICED SDK use a var in dhcp server to record next avail IP address).
Second dhcp client device startup at the moment, but always get *.*.*.2, this device will can't communicated with
other devices in the internet.
Implement DHCP decline msg will fix this issue.
Show LessHello Sir/mam
Now, we are using Cyw54907 cypress development board with Wiced 5.2.
i'm use it with example code snip/custom ie (which is based on vendor IE)..(it's Accesspoint Example)
but it's based on interworking IE or not.. i need to confirm about it. or any other example which is based on Interworkig IE..
i need to initiate my Accesspont with interworking IE or Vendor IE.
thank you
