Hello,

I am using a CYW43012 (Murata LBEE59B1LV) with LPC56407 (LPC546XX Microcontroller (MCU) Family | NXP Semiconductors) on a dedicated PCB. I use WHD library from Cypress with Free-RTOS and LWIP, I also have SDIO and GPIO ported from mcuxpresso. Used MCU has 512KB of Flash memory.

I want to create an access point or scan local networks. To do it I firstly need to upload the firmware to the CYW43012.

The project is taking too much flash memory - I get region 'PROGRAM_FLASH' overflowed error. Is there any way to make it smaller? I think 43012C0_bin is too big for my MCU.

Do you have any suggestions how can I manage it? Is CYW43012 WiFi possible to be implemented on 512KB MCU?

Thanks,

Piotr

Hi guys.

My intention is to make a WiFi board, which will replace a GPRS one, without changing our existing application a lot.  The app uses PPP to establish a connection to a mobile operator.  Did anybody test a case with PPP running on WICED?
My intention is to establish a PPP connection from remote target via Laird's EWB uart, and route with IP unnumbered (add proxyarp).

I read several lwIP threads in this forum (links below), installed WICED, successfully build snip.scan-LAIRD_EWB-FreeRTOS-LwiP-SDIO and its ThreadX variant to check, if there are any  build issues.   Awesome, both were built w/o a warning.

I added PPP from Savannah lwIP 2.0.3, even compared to 2.1.0, 2.1.1 and 2.1.2 releases, tried to redefine PBUF_POOL to PBUF_RAM, sys_jiffies() to xTaskGetTickCount() to fix build issues and played with 43xxx_Wi-Fi/WICED/network/LwIP/WWD/FreeRTOS/lwipopts.h - IP_FORWARD, PPP_SUPPORT, PPP_SERVER, etc.

Special PBUF_POOL_RX and PBUF_POOL_TX pools were created for WICED to handle wwd driver buffers.  I think PPP can have all its buffers in a local RAM.  Can I use the PBUF_RAM pool for them?

Delta changes done in WICED lwip 2.0.3 - BTW I did not find info about changes to 2.0.3, only changes against 2.0.2
Laird Sterling Wi-Fi Performance - probably use ThreadX + NetX for better performance

When I perform WPS with the library "wiced_wps_enrollee ()" of WICED-Studio-5.0, the code "3004" (PBC OVERLAP) is returned and WPS fails.
It occurs only when the wireless router (Buffalo: WTR M2133HP) is opposed to the confirmed range.
Could you please tell me the cause or possibility of this event?

WICED-Studio-5.0のライブラリ"wiced_wps_enrollee()"でWPSを行った際、"3004"(PBC OVERLAP)というコードが返ってきてWPSが失敗します。
確認出来た範囲で、無線ルータ（Buffalo製：WTR M2133HP）対向の場合のみ発生します。
本事象の発生原因或いは、可能性を教えて頂けませんか？

I know Cypress's FullMAC/HardMAC drivers are frequently updated and available. How about the SoftMAC driver? I can't find it in the community.

Noticed that Cypress FullMAC is patches based on upstream driver drivers/net/wireless/broadcom/brcm80211/brcmfmac. Does upstream driver drivers/net/wireless/broadcom/brcm80211/brcmsmac apply for Cypress Wi-Fi productions?

Thanks!

Hi,

I am using the CYW43907 as an IC and not as a part of a Module.

I would like to perform a boundary scan.

As far as I understand, in order to configure the boundary scan I must use the BSDL (boundary scan description language) file. 

I struggle to find this file for the CYW43907, It would be very helpful to get this file and some further documentations on how to use and configure this file.

If this file is supposed to be in the WICED environment, where can I find it?

Thank you! 

Hello,

Is there a way to let the wifi chip automatically  negociate  the country with AP ?

The need is to be to enable channels 13 / 14 by default  then let the  country  be set automatically

This is to ease device configuration

This exists on some other solution, but not found in WHD API.

Thanks,

Dear Team,

We are using LBEE5HY1MW module - which has CYW43455 cypress chipset in our design.

We wanted to know how BLE 2.4 GHz & Wi-Fi 2.4GHz co-existence is taken care in the cypresschipset.

* Please share us performance report for the above test condition.

Thanks

Helllo,

Could you let me know if CYW43455 supports Wi-Fi Enhanced Open?

Operation is assumed to be STA.

I would appreciate it if you could tell me if it is supported by the following latest FMAC.
