Dear Infineon-Team,
we are right now evaluating the CYW4373 chip for our wireless charging solution.
For this we would use your chip as an Wifi Station but we need to extend some frames with Vendor Specific Information Elements:
1.      Association Request Frame
2.      Reassociation Request Frame
3.      Probe Request Frame

Is this possible with your chip and is there any documentation?

fyi: Due to the fact that we are on a real time system, we will use a bare metal OS and no Linux.

Hi @StefanNagel ,

Yes, the "vendor_elements" in hostapd.conf will work for specifying the custom IE.

But since you are not using Linux here, you can look at the whd_wifi_manage_custom_ie function. There are no documents specific to this that are available.

Thanks

Dear Aditi,

do you have an update for that topic?

I learned that you can use in hostapd.conf the paremeter: vendor_elements

I furthermore noticed that you have an enum here:

https://infineon.github.io/wifi-host-driver/html/whd__types_8h.html#a07b4f24f4e2abacc45a9ad29f008488...

But Im not sure how to use that.

Kind regards

Stefan
