Hi,

I'm currently using the Murata LBEE5KL1YN-814 EVK which consists of CYW43439 module.

I've managed to load the driver package v5.15.58-2023_0901 backported for kernel v5.15.0-051500-generic on my Ubuntu 22 Virtual Machine.

However, when i connect the module to my PC, I received these READ errors:-

Please help to assist.

Thank you.

Hi Sir,

Does CYW43012 support DFS/Radar?

It seems not support after checking all firmware in fmac package by strings command.

I can't find -dfsradar in firmware tag.

Hi Sir

I  studied the datasheet and did some experiment on CYw43455. could you help me to find the answer?

1. as the datasheet of CYW43455 , it supports 7 ACL links and 3 SCO links. May I know whats the role of  device with the 7ACL links ?

(1 central to 7 peripherals , or 1 peripheral to 7 centrals?)

 2. if it cannot make up to 7 links , any guidelink to modifiy it ? what would be restricted to the links number ?

3. May I know why I cannot find the ACL/SCO links number to describe in ble datasheet ? such as CYW20704/6 series ?

We are facing this similar issue with three different configurations right now:

1. with the latest drivers and latest firmware files (hostapd v2.10)
2. with the latest drivers and older firmware files (hostapd v2.10)
3. with the older drivers and older firmware files (hostapd v2.10)

5 errors found in configuration file '/root/hostapd_test.conf'

Here, we are not able to set up the configuration for 40 or 80 MHz.

I am currently using MCU to drive CYW43438 module, but I cannot find any driver description documentation for this chip. Can you provide relevant documentations?
