Hi,

Hi all,

I have been trying to use NetworkManager together with cypress-fmac-v5.4.18-2021_0527 patches on mainline 5.4.18 kernel. Currently nearly all is working correctly except few issues, which were fixed together with little help from Beniamino Galvani of NM RedHat Team. My issue is in here Hotspot WPA3 support - this is the second half of the issue, because first one was solved with upgrading NM from 1.32 branch to 1.33. In brief, together with Beniamino we have discovered, that the driver is not returning RSN_AUTH_KEY_MGMT_SAE. We suspect that the problem is that the SAE AKM is not set in the NL80211_ATTR_AKM_SUITES netlink attribute by the driver. I have used grep to find it and i did not find any. My question is it possible that all suits are defined in the firmware and is it possible that this specific suite is missing? Is it possible for the cypress team to solve this issue because it is needed by the NM to set a wpa3 hotspot.

Dear Sir,

I need Raspberry Pi CM4 WiFi testtool for Rasbian 64bit. 

The purpose of the tool is to conduct WiFi RF certification with new WiFi antenna attached to Raspberry Pi CM4.

Can you provide the tool and useful information in that regard?

Thanks in advance.

Hi all,
I'm trying to use 2 PC respectively connect my 2 module to test throughput, but I don't know how the command to connect 2 PC.I found command for only one PC in the document. Attachment is  what I have tried.Please give me some suggestion. Thanks!

Hi,

With an another wireless module that support 802.11b and 802.11g, I could change the band through the hostapd configuration by setting the hostapd parameter hw_mode to b or g.

With the CYW43430, I am trying to do the same between 11b, 11g and 11n. But the settings are not taken into account.

As I understand, the hostapd parameter ieee80211n can be used to enable or disable the 11n. If I try to disable the 11n (I set ieee80211n to n and  hw_mode is g) and restart hostapd, the network scanning from another device (with iw scan) says the AP is still "bgn" and HT capabilities are enabled:

[...]
HT capabilities:
Capabilities: 0x21
RX LDPC
HT20
Static SM Power Save
RX HT20 SGI
No RX STBC
Max AMSDU length: 3839 bytes
No DSSS/CCK HT40
Maximum RX AMPDU length 65535 bytes (exponent: 0x003)
Minimum RX AMPDU time spacing: 16 usec (0x07)
HT RX MCS rate indexes supported: 0-7
HT TX MCS rate indexes are undefined
[...]

It should not if the parameter was really taken into account. Is it normal ? What am I missing ?

Best regards,

Anthony.

Hello,

We have the EVK-JODY-W163 ( CYW88359 and CYW89359) which support  Linux FMAC drivers. Do FMAC drivers support monitor mode?

Thanks in Advance,

Hello,

I'm trying to use CYBT-333047-02 with bluez stack in linux. The module is connected to Host PC over UART interface.
The hciattach and configuration runs smooth: the interface up and running, the configuration applied without errors.

hciattach /dev/ttyUSB0 any 115200 flow

hciconfig hci0 up
hciconfig hci0 piscan

hciconfig hci0 name myBtDevice
hciconfig hci0 class 0x011f00
hciconfig hci0 noauth

But I don't see my BT device in the air. Moreover, during the scan on Host PC I don't see any other BT devices.

I have also tried to execute the same HCI commands via CyBluetool without any success.
Tried to send HCI_Reset before the configuration, tried to send vendor specific command Enable_Radio, tried to configure new BD Address - nothing helps to see the devices in the air.

I have followed the recommendations from hthis topic https://community.cypress.com/t5/WICED-Smart-Bluetooth/HCI-Commands-to-enable-bluetooth/m-p/71433 but again without any success.

From the other hand, I have tried to use the TX carrier test mode (Set_TX_Carrier_Frequency_ARM) and was able to see the carrier on my spectrum analyzer.
It looks like the radio doesn't work during the normal operation. But it works in general (the TX test works well).

Am I forgot something? Should I sent any extra HCI commands, maybe vendor specific ones?

Thanks in advance,
Valeriy

Hi all,
as i have recently asked a question about WIFI (all is working flawlessly) now i'm woundering about BT with this chip because it does support it and i am wondering is it being turned on with fmac driver?
