Wi-Fi Combo Forum Discussions

Hi,

I am using CYW954907AEVAL1F development board. I was trying to enable Access Point in channel 34 with 40 MHz bandwidth. I am using WICED 6.4

The error i am getting is as below.

Set chanspec IOVAR failed result=2020

Error: wwd_wifi_start_ap failed

May i know what is the issue here? I also want to disable DFS for channel 52 @ 20 MHz bandwidth. We are doing a conducted test inside RF shield box. so, we are not interfering with other RF devices.

Can you provide us, information about above two queries?

Regards.

Hello,

I am using Wiced with the STM32L4 MCU, with ThreadX, and I'm looking into the power consumption while waiting for ThreadX events or message queues.

However, looking at Wiced platform files, it seems that the STM32L4 low power modes are not supported, am I understanding right? What would I need to be able to bring the MCU to low power?

Thanks for your help,

Best regards

<My situation>
I'm training WICED programing using CYW94343WWCD1_EVB. In this training, I'm refering the following two documents.

1) Cypress Academy WICED Wi-Fi 101 Book - WW101-02-Peripherals.pdf
https://github.com/cypresssemiconductorco/CypressAcademy_WW101_Files/tree/master/Labmanual

2) CYW943907AEVAL1F Evaluation Kit User Guide
https://japan.cypress.com/documentation/development-kitsboards/cyw943907aeval1f-evaluation-kit

  This document is not for CYW94343WWCD1_EVB.
  But I couldn't find the same document for CYW94343WWCD1_EVB.
  https://www.cypress.com/documentation/development-kitsboards/cyw94343wwcd1evb-evaluation-and-development-kit

  This docment describes how to debug (build, start GDB, etc.)

I tried to make two project. The first is Hello project. This is only for blinking LED, and run after download.
At resut, this worked fine.

The second is Hello2 project. This is also only for blinking LED, but stop after download for next debug step.
At resut, the following error occuerred after selecting "43xx_WiFi_Debug_Windows" menu.

    Exception condition detected on fd 760
    Remote communication error.  Target disconnected.: Success.

<My question/request>
Please tell how I can resolve the above error and start debugging at C source level.

My project needs to generate different configurations by adding  certain #define statements at the app level. We would like to be able to automate the build process so we need to pass these configurations from the command line. I got this sort of working by modifying the wiced Makefile and the application .mk file but it only works when the project is rebuilt or the app .mk file is edited (changes the timestamp).

Obviously i could add -B to make.exe to force all files to be rebuilt but this is time consuming with the size of the WICED.

Is there a way i can force the app .mk file do it can be rebuilt/reprocessed if the timestamp has not changed?

I am on Windows so doing something like $(shell touch ... ) to force the timestamp to change is not applicable unless certain dependencies are installed.

Hi There, I've been working on a project that receives data using an UDP protocol and stores the same into the SD card. While going through the sd_filesystem.c and sd_filesystem.mk already available in the WICED studio, i could see that platform supported are: BCM943907AEVAL1F* CYW943907AEVAL1F CYW943907WAE4 BCM943907WCD2. The one that I'm using is Search Results Web results  CYW954907AEVAL1F Evaluation Kit. Kindly help fixing the issue.

I'm basically using two files: udp_receive.c and sd_filesystem.c to create this project.

Also, is this the only way to fetch data over Ethernet and store in SD card? or there are any other methods available too?

Hello,

I would like to play with Bt 5.1's direction finding, AoA, AoD, and I just saw this  Kit CY8CPROTO-062-4343W.

I see that it has a Murata module on it supporting Bt 5.1.  Should I rather be looking at a board with Nordic chip, or Murata will be as good?

Thanks for advice in advance.

Hi,

In my project I'm using SIP based on STM32F412 + CY4343W.

Looking at some demo projects using resources (e.g. SPI bus), I didn't notice any locking mechanism (mutex etc.)

My questions are:

1. Is access to a system resource, e.g. wiced_spi_transfer() is protected using mutex in case several threads are accessing the same resource concurrently?
   I followed the calls wiced_spi_transfer() --> STM32F4xx/platform_spi_transfer() and didn't find any locking...
2. If not, how this resource can be protected? I know when to lock a mutex but don't know when to unlock it, especially if using DMA (unless the call is blocking. See next question)
3. Does the SPI transfer wiced_spi_transfer() runs in a blocking manner (i.e. running to completion before returning)?
4. If it runs in blocking manner, does it spin looping till completion, or does it sleep (rtos sense)? It has huge implication on system performance...

Thanks in advance for any advice

Hello,

we want to use PHY Layer Information (CSI - channel state information, to be specific) from CYW43907. We figured that we would need a special firmware for the wifi-part of the chip. Is this in any way possible? If so what do we need to be legally allowed to do this and use it in a commercial product?

Best regards

Has the CyW43340 been demonstrated to function with the Mesh protocol? Im not seeing any dialog about that in the spec. though 5.0 should handle it. Our intention is to use it to manage BT-LE and BT-MESH concurrently with WIFI. 

Is there is a more appropriate forum for the CyW43340?
