WiFi certified with the CM4 - How to ?

[fischeor]

Hello,

We are a manufacturer of gateways and intend to get the "WiFi Certified" approval of the WiFi Alliance with the Raspberry Compute Model 4 (https://www.raspberrypi.com/products/compute-module-4/?variant=raspberry-pi-cm4001000).

The Chip on the CM4 is the Broadcom BCM43455 aka Cypress CYW43455.
I understand that Infineon is now responsible for support.

What support do you offer for these tests, are they feasible with that hardware and what role does the WICED Software Suite play in this?

Any help or information would be greatly appreciated.

Thanks and greetings,

Oliver Fischer

Hi @fischeor ,

For WFA test cases, there are third-party testing labs that take care of doing such certifications.

The labs will have the tools and testing scripts to conduct the certification.

From Infineon, we have the latest Linux FMAC drivers for the 43455 available here: https://community.infineon.com/t5/Wi-Fi-Bluetooth-for-Linux/Cypress-Linux-WiFi-Driver-Release-FMAC-2...

WICED/Modus ToolBox is for RTOS-based solutions. Since you are running Linux/Android in your CM4, you won't be needing it.

Thanks

Hi Raks_99,

thanks for the information about the WiCED software we don't need and the link to the most current drivers.

From your post, it reads as if we need to install the newest drivers, maybe update the firmware, and then can go the   labs, pay and get the certification - nothing else to do ?

Is this correct, or are there known problems when trying to get certified ?

The reason for the question is that we don't have the hardware to conduct the tests in advance and cannot see if we will fail in any.

I have read that there are some scripting tools that would set the WiFi settings according to the different tests - so that the tester don't need an user interface for setting up each test. Do you know about such kind of tools ?

Do you know of any successful "WiFi Certified" application with the Raspberry Compute Model 4 ?

Thanks and greetings,

Oliver

>>Is this correct, or are there known problems when trying to get certified ?

Internally, we run through the same set of test cases before the new driver and firmware release. So there shouldn't be any such problems.

Yes, there are test scripts that automatically run through the test cases. The test labs will be provided with these scripts by the WFA.

>>Do you know of any successful "WiFi Certified" application with the Raspberry Compute Model 4?

I'm not really sure, maybe RPI has the answer.

Thanks and Best Regards
