Wi-Fi Bluetooth for Linux Forum Discussions

Hi Team,

I am trying to bring up Bluetooth in UART using CYW43455 module.

I have done the following steps:

1. Enabled BT_REG_ON to output high.

2. Bluez has been set up in the board.

3. Copied the firmware from cyw-bt-patch/BCM4345C0_003.001.025.0144.0266.1MW.hcd at master · murata-wireless/cyw-bt-patch · GitHub  to /etc/firmware folder.

4. I did hciattach and following are the logs.

$ sudo hciattach -t 30 /dev/ttyTHS1 bcm43xx 3000000 flow bcm43xx_init Set Controller UART speed to 3000000 bit/s Flash firmware /etc/firmware/BCM4345C0_003.001.025.0144.0266.1MW.hcd Set Controller UART speed to 3000000 bit/s Device setup complete

5. Then I tried pairing with bluetoothctl and got the following logs:

$ sudo bluetoothctl [NEW] Controller 48:EB:62:C2:B8:C7 BlueZ 5.48 [default] Agent registered [bluetooth]# agent on Agent is already registered [bluetooth]# default-agent Default agent request successful [bluetooth]# scan on Discovery started [CHG] Controller 48:EB:62:C2:B8:C7 Discovering: yes [NEW] Device 75:6E:A7:64:9C:05 75-6E-A7-64-9C-05 [NEW] Device 94:65:2D:99:CD:12 793ffad1 [NEW] Device 0D:61:95:00:1C:9B boAt Rockerz 600 [bluetooth]# scan off [CHG] Device 0D:61:95:00:1C:9B RSSI is nil [CHG] Device 94:65:2D:99:CD:12 RSSI is nil [CHG] Device 75:6E:A7:64:9C:05 RSSI is nil [CHG] Controller 48:EB:62:C2:B8:C7 Discovering: no Discovery stopped [bluetooth]# pair 0D:61:95:00:1C:9B Attempting to pair with 0D:61:95:00:1C:9B [CHG] Device 0D:61:95:00:1C:9B Connected: yes Failed to pair: org.bluez.Error.AuthenticationFailed [CHG] Device 0D:61:95:00:1C:9B Connected: no

I am getting the above issue " Failed to pair: org.bluez.Error.AuthenticationFailed ". Can you help me resolving this issue?

Thanks,

Apologies if this is answered elsewhere, but I haven't found it yet after a fair amount of digging.

Do any of the Cypress 11ac combo parts support mbss (multiple BSS/SSID), and if so, where could we find the firmware versions that support that?  There doesn't seem to be a list.

Thanks

Hi,

we have a custom embedded system based on freescale vybrid vf6xx SOC.

-run kernel 4.3.0

-looking to replace wifi chip with murata mw1, that uses cypress 43355 chip.

-bt part is working fine.

-updated/patched the "/drivers/net/wireless/brcm80211/brcmfmac" driver to:

     -download fw and related files.

     -create wlan0 interface. OK

          root@E8c08d60d461f7:/root $ ifconfig wlan0

Any help on this issue will be greatly appreciated.  

Hi,

I have a 43456 based SDIO module with which I'm having AP throughput issues. I've tested both current mainline Linux v5.9 and also Linux v5.4.18+brcmfmac patch set from the 2020-09-25 driver release.

I have a very simple hostapd config which consists of:

interface=wlan1

driver=nl80211

ctrl_interface=/var/run/hostapd

ssid=test

channel=11

ieee80211n=1

hw_mode=g

ignore_broadcast_ssid=0

Then connect a device, in this case iPhones and the Samsung S8 are particularly sensitive to the issue, run an iperf3 server on the STA and run a throughput test from the AP. I then find dropouts where either the driver or the firmware seems to be stalling and throughput drops to zero. Please see an example below:

[root@alarm ~]# iperf3 -c 192.168.10.96 -t 60

I have tested on different channels, under a multitude of conditions including a very remote countryside setting with no AP's in the vicinity. Can you confirm these results?

I am also wondering why there are no firmware releases for the 34356 chipset, I'm having to use ones that I find randomly on the internet. The current latest firmware I have available is one from July 2020, however I haven't yet found a firmware without this issue.

Regards,

Jack.

Hello,

We are running brcmfmac with a big-endian host (powerpc).

The attached patch enables basic operation (firmware load, association, some network traffic), but the driver eventually enters into an infinite loop with I_DE (descriptor protocol error) set in intstatus. This is with kernel v5.9, bcm4343w and firmware 7.45.98.97, which run without issues with a little-endian host.

The following sequence repeats (log file is attached):

brcmfmac: brcmf_sdiod_oob_irqhandler OOB intr triggered

brcmfmac: brcmf_sdio_intr_rstatus intstatus=0x00c01040

brcmutil: RxHdr:

00000000: 00 00 00 00 00 00 00 00 00 00 00 00 ............

brcmfmac: brcmf_sdio_readframes processed 0 frames

There must be another instance of a missing endian conversion that causes this descriptor protocol error, correct? Any suggestions on where to look? I'll review the patches from the fmac driver realease v5.4.18-2020_0925 that are not in upstream, but nothing jumps out at first glance.

Thank you,

Remi

Dear experts,

Does CYW88373 support simultaneous STA + AP operation in Linux?

Is there a minimum driver version requirement for such support?

Thanks,
