Wi-Fi Bluetooth for Linux Forum Discussions

Is there any user manual or bring up sequence for murata 1XA bluetooth? I want use bluetooth on my specific evb but don't know how to enable it. etc. which driver? any patch? device tree? firmware?

Hi Team,

We have integrated CYW43444 module with android and everything working properly.

We have to do RF testing for WIFI.

We have WL binary.. 

But We are getting error for somw commands. Can you please help here.

evk_8mm:/ # wl pkteng_start 00:11:22:33:44:55 tx sync 40 1000 0
wl: error -23

evk_8mm:/ # wl country ALL
wl: error -2

evk_8mm:/ # wl phy_watchdog 0
wl: error -23

Requirement :

1. Transmit in continuous wave mode.
2. Transmit in Packet mode (No of Packets configurable).
3. Transmit in continuous stream (duty cycle more than 90%).
4. Receive in packet and continuous mode (Time configurable).

What needs to be done for above requirement? 

Also following commands are not working:

10 wl country ALL
11 wl dump
12 wl pkteng_start 00:11:22:33:44:55 tx 20 1500 0
13 wl pkteng_stats
14 wl nvram_dump

Thanks

Hi All,

My company use BCM43455 wifi- Bluetooth modules in our product. For Radio testing of both wifi and BT, I have to put them in test mode for transmitting continuously on different frequencies. How can I achieve that through Linux?

Can somebody please share how that can be done?

Any reply is really appreciated.

Thanks,

Hi Team,

We have integrated cyw43455 with IMX8MM processor in android 11 code base and it is working fine.

but as per the requirement we need to disable wifi for sometimes using reset pin. 

When I make

1. regon pin (reset pin) low - WIFI disable 

2. After that making regonreset pin high - WIFI should turn on (but it is not working) . - looks like power on sequence issue.

Could you please help here to disable wifi using reset pin? What changes need to be done here ?

thanks

Hi,

I want to port driver for CYW43455. I used this  Cypress Linux WiFi Driver Release (FMAC) [2020-06-25]  ,

Target platfrom is ST sta1275 DV12.5,

During the cross compilation of modules, I have seen the following warning.

root@sta1275-evb-mmc:~/aher_ko# insmod compat.ko
insmod: ERROR: could not insert module compat.ko: Unknown symbol in module

dmesg shows :
[ 59.569745] compat: Unknown symbol kmem_cache_alloc_trace (err 0)
[ 59.569905] compat: Unknown symbol __gnu_mcount_nc (err 0)

Could you help to fix this issue? Thanks a lot.

I am interested in using wifi easy connect/Device Provisioning Protocol, but the brcmfmac driver that is in upstream Linux kernel does not seem to have support for it.

I see in the linux-wireless mailing list archive that you did do one attempt to send in a patch for it back in December 2020.

But that one was rejected because your patch did not apply cleanly to latest Linux tree: https://lore.kernel.org/linux-wireless/20201209072159.354AAC433ED@smtp.codeaurora.org/

I do not see a second attempt.

What is the reason for this?

And is it only the kernel were the support is still missing, or is there also still work on the firmware side to be done before easy connect is in an usable state?

Hi All,

We are using CYW43012 chipset and here are our details:

Firmware version:
1.21 RC0.0
wl0: Feb 21 2022 07:19:28 version 13.10.271.283 (211da63 CY) FWID 01-18f4ac2
Driver Version:
Backported Linux Version v5.10.9-2022_0321-0-ga0971bc0b123

wl clmver:
API: 18.2
Data: 9.10.0
Compiler: 1.36.1
ClmImport: 1.34.1
Creation: 2019-12-13 03:26:37

We are using roam_off=0 option so that roaming decisions are taken by host and do post connection scan i.e. background scan from driver.

We have observed that firmware is trying to send Null Data packets in unconnected state and retries sending multiple times as no AP responds (as expected) causing intermittent packet loss as we are not in home channel.

Attached a pcap where the device is connected in Channel 36 but it tries to send Null data in channel 40 as well continuously. We are not seeing this issue in CYW43455 chipset product we have with the same driver and firmware.

Any help ASAP is deeply appreciated. @raks_99  @GauravS_31  @VinayakS_26

Hello, 

We are using a CYW43455 on Android 11, linux kernel 5.10.72 (NXP BSP)
The bring-up went OK with brcmfmac driver and wpa_supplicant. We are now able to use the wlan interfrace.

However the Compatibility Test Suite (CTS) reveals that we don't have a proper Wifi HAL. There used to be a specific HAL for bcmdhd driver, but this driver has been removed from recent kernels.

Is there a recommended wifi HAL for brcmfmac driver ?

Best regards,
