Hi All,

I am planning to make a client to connect to the https server with WiCED.

Then I hope to disable the server certificate validation check.

The SSL/TLS handshake process I have mentioned is as follows.

I checked the URL "The SSL/TLS Handshake: an Overview - SSL.com" .

          https://www.ssl.com/article/ssl-tls-handshake-overview/

In the third step

          "Client verifies the server's certificate, then extracts the public key ....... .......

           ..................... then sends it to the server."

I want that the Client does not verify the server's certificate.

Is there any client-side sample code like this ?

Hello,

We are employing your CYW4356 WiFi transceiver to connect our android device to our WiFi network.

The objective is to use 802.11ac standard to benefit it's transmission speed.

We are using a Technicolor TC7230 WiFi router.

WiFi router specification: 5.0 GHz (3x3) IEEE 802.11ac AP with IEEE 802.11ac compliant transmit beamforming

Technical Datasheet:

https://www.normann-engineering.com/products/product_pdf/premise_equipment/technicolor/tc7230.pdf

Specifically we use an AMPAK AP6356 module (integrates a BCM4356/CYW4356), our android device's CPU is an Amlogic S905X2 and our device has 2 physical antennas.

AMPAK AP6356 Technical Datasheet:

http://rockchip.fr/ampak/AP6356_datasheet_V1.0_07252014.pdf

We perfomed multiple speed tests and used different WiFi network analyzers to know what was the transmission speed and MIMO,Modulation and Encoding used.

WiFi network analyzers informed us PHY speed 866.66 Mbps, which means 2x2 MIMO 256QAM 5/6 Encoding.

But real speed is 200 Mbps (we never obtained greater than 250 Mbps)

We performed the same test (same test conditions) with another android 2x2 MIMO device (PHY speed 866.66 Mbps) and real speed was 446.6 Mbps (always around 400-450 Mbps)

We know MAC efficieny determines real speed, reducing PHY speed around 50%-70% (such as the other android device tested)

We are trying to understand why speed is so low.

Is it due overheads such as interframe space, ACKs or MAC headers?

Is there any other cause that can reduce the real speed?

Thank you for supports,

Kind regards,

Antonio Valbuena Sánchez

We are currently developing our design using 1DX Murata module based on CYW4343W chipset. But later we are planning to use 1FX module based on CYW43364 chipset. Both 1FX & 1DX are drop in replacement while 1DX gives additional feature of Bluetooth which are no connect lines for 1FX.

Are both the modules software compatible? We are currently trying with NXP iMx Series Parts which are using WICED drivers.

Hello,

I have completed the WICED WiFI Tutorial.  https://www.cypress.com/training/wiced-wi-fi-101-video-tutorial-series

I am working on AWS application using the development kit CYW954907AEVAL1F.  in Chapter 8 of the AWS tutorials, there are three versions for establishing connection with AWS Cloud. When I run the code MQTT, I am catching some error with initialization of MQTT.

I have checked my policies are consistent with following this post (AWS MQTT TCP receive error )

I am not sure what is error code 4, and I am also not sure how to debug this as the code was written for the dev kit, and I have only changed wifi access SSID/PC, and the endpoints, and Topic related information in AWS.  My certificates and Thing are working as desired with other scripts, but the MQTT code provided on GitHub is providing this error.

Thanks for any guidance on this issue.

Recently a couple of documents surfaced both on Cypress's site and Murata's, claiming the CYW4343W supports BT5.1.  The datasheet still only claims support up to BT 4.1.  Does anyone know what features of BT5/5.1 the CYW4343W actually supports, if any?  Or is this a copy n' paste error that got out of control? 

Product brief referencing BT 5.1:

Murata module page also claiming BT 5.1 (type 1DX module):

https://wireless.murata.com/products/rf-modules-1/cypress-based-modules.html 

And actual Murata datasheet for the 1DX module, with CYW4343W, claiming BT 5.1:

Thanks!

Hi All,

What should I do if I would like use TLS without server authentication ?

Should I just build without a root certificate?

In the TLS Security related API, authentication is done explicitly,
so should I give up that API function?

i want to test coexistence with cypress wifi. ( i'm bt developer)

i have cyw43012(murata module) and cyw43364(cypress module).

Can both module test external bt coexisttence (3-wire)?

I will buy linux host board and get default nvram.txt(from cypress support?).

how i change nvram.txt for ext 3-wire coex?

I red below document. but I could'nt find coexistence.
