Wi-Fi Bluetooth for Linux Forum Discussions

Hi everyone,

I need high power sdio 2.4g 1T1R wifi module in my project. But can not find it.

Now I want to use bcm43362 wifi chip with external PA to extand signal distance.  The rf output is 23 - 25dbm.

The internal PA output in bcm43362 is 14dbm and can't satisfied this target.  The rf input of external PA is as low to -3dbm so bypass the internal PA is the only way.

Does anybody know how to bypass the internal PA of bcm43362?

Looking for a comprehensive list of WPA Enterprise security modes that are supported by the CYW4343W when used with wpa_supplicant (using latest brcmfmac driver).

Are all Enterprise security modes supported that are listed by wpa_supplicant here?

Hi All,

I am checking the README file content in FMAC Driver Package (v4.14.34-2018_0625)
I have some questions about Supported Feature with README file content .

[Question]

At v4.14 (Previous version), CLM Download feature is supported with 4373/43455/4343w/4354/4356.
On the other hand, at v4.14.34 the CLM Download feature is supported with 43455/4343w/4354/43012.
The 4373 and 4356 device are out of scope.
Why are these exempts ?

At P2P Feature ,43012 device is excepted.
Is there any reason for 43012 to be out of scope?

Best Regards,
Sakagami

Hi，

The defaule value of PCM clock is 512KHz, but we want to set 128KHz, so I config cyw43438 as follows:

1, Write_I2SPCM_Interface_Param

[MiniBoard]# hcitool cmd 0x3f 0x6D 0x01 0x01 0x00 0x00

< HCI Command: ogf 0x3f, ocf 0x006d, plen 4

  01 01 00 00

> HCI Event: 0x0e plen 4

  01 6D FC 00

2, Write_SCO_PCM_Int_Param

[MiniBoard]# hcitool cmd 0x3f 0x1C 0x00 0x00 0x00 0x01 0x01

< HCI Command: ogf 0x3f, ocf 0x001c, plen 5

  00 00 00 01 01

> HCI Event: 0x0e plen 4

  01 1C FC 00

3, Write_PCM_Data_Format_Param

[MiniBoard]# hcitool cmd 0x3f 0x1E 0x00 0x00 0x03 0x03 0x01

< HCI Command: ogf 0x3f, ocf 0x001e, plen 5

  00 00 03 03 01

> HCI Event: 0x0e plen 4

  01 1E FC 00

Then，I  Read the cyw43438 config,

1, Read_SCO_PCM_Int_Param

[MiniBoard]# hcitool cmd 0x3f 0x1d                   

< HCI Command: ogf 0x3f, ocf 0x001d, plen 0

> HCI Event: 0x0e plen 9

  01 1D FC 00 00 00 00 01 01

2,  Read_PCM_Data_Format_Param

[MiniBoard]# hcitool cmd 0x3f 0x1f

< HCI Command: ogf 0x3f, ocf 0x001f, plen 0

> HCI Event: 0x0e plen 9

01 1F FC 00 00 00 03 03 01

[MiniBoard]# 

The PCM/SCO is configed successfully, but the PCM_CLK is still 512KHz when I mesaure the PCM_CLK signals with an oscilloscope.

What should I do so that I can config cyw43438's PCM_CLK work at 128KHz?

Hello Folks,

For my MSc thesis, I am trying to develop directed antenna for wifi communication to save some power for IoT devices compared to onboard/external omni-directional antennas.

For that 2 questions:

1-) How can I modify the tx/rx power to an antenna? If it is possible of course.

More specifically I am interested in Particle-Photons, which they use Cypress WICED I believe.

2-) How can I modify the wifi subsystem to select specific antenna (assuming I have multiple directed antennas, like 4 of them towards North, South, East, West) ?

I guess it will be nice if I can put the antenna number somewhere. I also do not know if current wifi standard has something like "antenna number" in the packet format.

Please suggestions and ideas.....

All the best

I have a customer trying to use the iMX7s-warp board, which has a type-1dx module (CYW4343W)

Our latest FMAC driver and firmware supports kernel 4.1.15 which has no MACHINE imx7s-warp

They imported the Yocto meta-layer for the imx7s-warp from another BSP but this overrides the preferred kernel and pulls in 4.1.32 in which then it becomes a kernel source/header file headache for FMAC.

The current Yocto BSPs all support the imx7s-warp ( 4.1.32 up ) and have the bcmdhd and brcmfmac drivers within, the brcmfmac doesn't actually work but as it's close to FMAC as far as I know - it may be a good starting point for a possible port?

Can we provide some guidance on how to enable this feature? for reference this works ok on the iMX7d board, just not the WARP one.

Hi,

While doing suspend and resume with the battra release of fmac driver on IMX7 Platform Linux ver 4.9, I am seeing the following failure messages.

All iovar calls inside the brcmf_cfg80211_resume function are failing.

Has anyone else seen this issue? Is there a fix available from cypress for this?

I am calling suspend by "echo mem > /sys/power/state"
