Hello,

Hardware: Murata Type1LV module(CYW43012) + PSoC CY8C624ABZI-S2D44

Software: Infineon's wifi host driver(https://infineon.github.io/wifi-host-driver/html/index.html)

 

Is it necessary to setup power table to meet FCC/EU/JPN clearance?

Supplier provides power tables for FCC/EU/JPN 2.4GHz/5GHz Indoor/Outdoor.

There's no concept called "installing" when it comes to .clm_blob

If you're asking how this gets downloaded when using WHD, the file 43012C0_clm_blob.c at https://github.com/Infineon/wifi-host-driver/tree/master/WiFi_Host_Driver/resources/clm/COMPONENT_43... gets compiled and downloaded along with the firmware.

Now if you already have a BLOB and are stuck on how to convert it, use the perl script attached in the .zip file and fire the below command.

bin_to_c.pl wifi_firmware_clm_blob_image_data <chipname>.clm_blob > <chipname>_clm_blob.c

This will give you structure with a bunch of numbers, take these numbers and replace them as is in the original 43012_clm_blob.c file and you will be able to download the file that you need onto the chip.

Now if you don't have a BLOB and need a new BLOB built for you, please go through Introduction to Infineon’s WiFi Regulatory flow - Infineon Developer Community and it will help.

If you are using Murata's module as is out of the box. It should have the needed certifications. But I would recommend checking with them to ensure you have the needed clearances.

Thanks for quick reply.

 

Murata provides the power tables but they only support Linux driver.

I would like to know how to download the power table using Infineon's WHD.

We got power table file from Murata to meet FCC/EU/JPN regulation.

The power table format is Excel.

We would like to know how to setup power table with Infineon's WHD.

If you can communicate using private channel, I could share the actual table.

We are using Murata's Type1LV module and their standard PCB antenna.

They said that to meet FCC/EU/JPN regulation, we should install the power table file to the module.
However, they only support in case of Linux driver to install the power table.

I would like to know how to install the power table using Infineon's WHD.

Thank you for your reply.

We will contact to Murata to get CLM BLOB.

After that we can convert BLOB to C using your tool "bin_to_c.pl".

Thanks!
