Hello,

Is there any mean to configure CYW4343W chipset to transmit permanently on a given frequency?

Hi Sir,

I was testing wl cmd,there were some error,please help to check,my cmd as below:

wl mpc 0

wl up

wl band b

wl channel 1

wl curpower

Error: read ppr board limit failed

Chip number:cyw43438

OS:     Android 7.1

CPU:  Allwinner

The attached are Doc and my actually test  .

Thanks,

Leo

Hi

Normally, in Linux systems, country specific frequency-band and power settings are defined and handled via regdb.
The 89359 brakepad driver uses a CLM blob to define band and power settings.
How is the relation of CLM to regdb in this driver? Are regdb values used by the driver or can the settings only be done via CLM blob?

Kind regards

Stefan

I'm used i.MX6UltraLite EVK with Murata 1mw module

I need to enable interworking tag(107) in Access Point, I have setup a configuration for hostapd that provide it but it is does not show up when i am scanning the Access Point, only custom Vendor Id seems supported"""

hello：

cyw43340 OTP document is as follows：

1.What are the meanings of pa0b0,pa0b1 and pa0b2 respectively, and what are the validity of their respective parameters ?

How should we adjust the parameters according to our actual circuit ?

2. Pa1lob0,pa1b0, and pahib0 correspond to 5 GHz low-band, 5 GHz mid-band, and 5 GHz hi-band, respectively !

  What is the frequency range corresponding to 5 GHz low-band, 5 GHz mid-band and 5 GHz hi-band respectively ?

We are using 43340 for rf performance test and have encountered some problems, so we want to know how to adjust it. We hope to get a reply as soon as possible. Thank you !

hello:

I am testing the receiving sensitivity in non-signaling mode. How to calculate the bit error rate according to the returned information,as follow:

I think there is no problem with the test method I used. I just don't know how to convert it,thanks!

hello

cyw43340  Tx power can be adjusted,I have the following questions:

Refer to otp document:

maxp2ga0=0x46,max output power is 17.5dbm,the nominal power is 17.5 – 1.0 = 16.5 dBm.

What is the actual power output if the following configuration is used:

maxp2ga0=0x46

ofdm2gpo=0x44444444(back-off power is 2dbm)

when rate is 6Mbps,The actual output power should choose which of the following?

1.max output power(17.5)-2dbm =15.5 dbm

2.the nominal power(16.5) - 2 dbm = 14.5 dbm

think you!

hello:

In the following two paths for wiced 6.4:

paths 1:43xxx_wifi/platforms/BCM943340WCD1/wifi_nvram.h

paths 2:43xxx_wifi/platforms/BCM943362WCD4/wifi_nvram.h

The following two parameters are different:

    "edonthd=-65"                                                        "\x00"

    "edoffthd=-71"                                                       "\x00"

Path 1 doesn't exist. Path 2 does

I want to know the meaning of these two parameters and their impact on wifi usage,thinks!

I'm looking to FCC certify a Nvidia Jetson TX2 product which uses the BCM4354 module. It appears that in order to put the module into continuous transmission mode, I require the "wl" utility. Unfortunately, the SDK that Nvidia provides does not include this utility.

I've located these two other posts that seem relevant:

https://community.cypress.com/message/144616#144616

https://community.cypress.com/message/199171#199171​

Based on these posts, I have a precompiled ARM version of wl that is executable on the TX2, but it's not able to actually execute any commands. This leads me to believe that in order for wl to work, I require the bcmfmac driver instead of the bcmdhd driver that's currently used, but I can't find any documentation that confirms this.

Any help in acquiring a working wl tool would be greatly appreciated. Do I need to get bcmfmac loaded in order to do this?

Thanks,

It seems that the Hardware TSF implemented by WiFi controllers is a useful source of a synchronized time datum across the devices connected to a single WiFi network.

I see that this question hardware timestamping  about accessing TSF in an earlier WiFi chip received the negative response "Synchronizing TSF with host MCU is not supported on Wiced."

I would like to know if - and how - the CYW43455 TSF can be accessed by host software or driver (typical host might be RPI3B).

Thanks!
