Hi,

I would like to modify (increase) the TX power of the WiFi. 

• IOVAR_STR_QTXPOWER is the correct variable to use for changing TX power?
• What value shall I set in IOVAR_STR_QTXPOWER in order to get the maximum TX power?

Thanks,

gca.

Hi.

I am currently using Laird LWB+ CYW43439 with WHD successfully in AP and STA modes.

But now I would like to use it in WiFi Direct/P2P mode.

Is it possible to use Laird LWB+ CYW43439 and WHD for WiFi Direct/P2P mode? If so, what would I need? are there any examples?

Thanks in advance.

gca.

Hi, 

We are waiting on the serial flash support on modustoolbox for the cyw43907. Our aim is to implement OTA and also read /write some data on the flash.

Is it still planned to be implemented?

Thanks,

Cédric

Could you please answer the following question we received via social media?
Question: @infineon what's the size of the CYW55572 chip?

Using Fedora38 on two systems with BCM4356 802.11ac Wireless Network Adapter I get these messages and WiFi results:

2.4GHz and 5GHz are not working

For both cases I have tried with several available firmware files that we can get from linux-firmware and although I get rid of the log error, nothing changes.

For the imx board, we need a configuration file to get the 2.4GHz band working and get a correct association although 5GHz band is still not working. The configuration file that I have tested is a generic one (https://chromium.googlesource.com/chromiumos/third_party/linux-firmware/+/f151f016b4fe656399f199e28cabf8d658bcb52b/brcm/brcmfmac4356-pcie.txt).
While, for the commented intel platform, the configuration file is not necessary to get the 2.4GHz band working and get a correct association but 5GHz band is not working with everyone I have tried.
I have read that this configuration file is related to some nvram configuration values but nothing else.

We would need to be able to use the 5GHz band for both cases.

I have asked to NXP, Intel and Broadcom and everyone redirects me to Infineon in order to solve these issues with this card.
Could yu help me? Could you clarify which firmware and configuration files are necessary?

Thanks

Continuation of the thread "BCM4356 802.11ac Wireless Network Adapter configuration file (Linux)" that was closed but, sorry,  the solution does not work for me.

I mean using the content of the firmware folder (pcie.bin and/or blob file), I have the same behavior, that is, 5GHz band is not working.

In order to confirm, if I have BCM4356 which files should I use?

I think that I would need some confiuration file (*.txt) to get this, could you help me?

Thanks

Let me paste again the content of the initial thread:

Hi,

On the imx8mp solid run board, I'm attempting to activate the AP mode for Wi-Fi settings.

And to enable AP mode, I followed the instructions listed below. But I'm struggling a little.

Steps Followed:

modprobe moal mod_para=nxp/wifi_mod_para.conf

vi /etc/hostapd.conf

     interface=mlan0
     ssid=test
     hw_mode=g
     channel=1
     ieee80211n=1

iwlist wlan0 freq

killall wpa_supplicant

killall hostapd

ifconfig wlan0 192.168.1.10 netmask 255.255.255.0 up

route add default gw 192.168.1.1

hostapd /etc/hostapd.conf

Log:

root@imx8mpsolidrun:~# hostapd /etc/hostapd.conf

wlan0: interface state DISABLED->DISABLED
wlan0: AP-DISABLED

Please let me know if the process i have followed is correct.
