Wi-Fi Bluetooth for Linux Forum Discussions

I try to connect a module using CYW88373 to imx8qxp-mek using sdio.

Operation of the same module was successful in imx6ul-14x14.
However, there is no wifi-related part in the dts setting of imx8qxp-mek.
Which dts setting can be added to make it work at imx8qxp-mek? 

Or, CYW88373 doesn't  support kernel 5.10.35?

kernel git is this: git://source.codeaurora.org/external/imx/linux-imx.git (HEAD: lf-5.10.y tag: lf-5.10.35-2.0.0)

imx6ul-14x14 defconfig: arch/arm/configs/imx_v7_defconfig
imx6ul-14x14 dts: imx6ul-14x14-evk-btwifi.dts (work well)

imx8qxp-mek defconfig: arch/arm64/configs/imx_v8_defconfig
imx8qxp-mek dts: imx8qxp-mek.dts

Hi everyone,

I am programming an ZYNQ Board (with Cypress CYW20704 A2 Bluetooth Chip) that uses Petalinux to receive Audio from Phone and send that Audio A2DP to another Bluetooth speaker.

My problem is that the sound I get is an active sound with frequency 44100 Hz (capture) and the output (playback) is again 48000 Hz.

Is there a way for me to increase the Audio Sink Codec Configured to 48000 Hz. Because bluetooth speaker is fixed at 48000 Hz. 

I read in the datasheet that we can change the Sampling Frequency in the following formats:
0x80: 16kHz
0x40: 32kHz
0x20: 44.1kHz
0x10: 48kHz

Is there a way to use hcitool cmd command to increase Sampling Frequency to 48 kHz?

Thank you very much.

Hello Everyone,

My company is using Murata 1mw module in our product. Wifi connection drops/disconnects often. We are using the following firmware version for wifi  7.45.229 (617f1f5 CY) and the same issue is with  version 7.45.184 (r712131 CY)
The same issue has been discussed on RPI forum -

https://github.com/raspberrypi/linux/issues/3849#issuecomment-822341133

Is this a known issue? Can somebody please suggest the solution for it?

I have attached dmesg output, if any more logs are needed, please let me know.

Thanks,

Asma

Any one send me a wl tool static complied for arm926t cpu?

or can we download the wl source code from some where and complie it by ourself? and where is the source  code?

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,

The latest FMAC driver doc mentioned WPA3 is supported in STA and AT mode.

Cypress Linux WiFi Driver Release (FMAC) [2021-05-27] 

I just want to double confirm does WPA3 feature support in ALL chip FW(or module, see attached file. whatever SDIO/PCIe/USB) listed on doc??

Thanks.

Austin

Hello, expert

Our product use AW-NM372SM as wireless connect, the chipset of AW-NM372SM is cyfmac43430.Wifi driver is cypress-wifi-v5.4.18-2021_0527, it work well with cyfmac43430-sdio.bin & cyfmac43430-sdio.txt(both are from AZUREWAVE).

Now we need to some RF test and need to replace cyfmac43430-sdio.bin with the cyw43438-7.46.58.26_mfg.bin(also from AZUREWAVE), But at this time the wifi driver fail and exit.
