Hello,

I use "fqacurcy" command to set CYW4354 to transmit CW(continuous wave, non-modulated) signal, it works, but the CW signals are transmitted thru both Core0/Core1.

I tried to add "txchain" command to control it, but the CW signals are still transmitted thru both Cores.

How can I set it to transmit CW signal thru specified path?

 

Thanks for your help.

Hi @FrYa_4831451 ,

When using the CW mode testing the power is always maximum and cannot be change, the maximum power is set by the CLM.

Hi @FrYa_4831451 , Could you please share us the full command list used to set continuous wave?

From the wl document link -> https://community.cypress.com/t5/Public-Archive/WL-Tool-for-Embedded-802-11-Systems-CYW43xx-Technica... the command "txchain"  take the values 1 - Chain 0 only
2 -Chain 1 only
3 -Chains 0 and 1

Could you please conform if you tried setting txchain to 1 or 2?

Regard, Vivek.

Hi Frankie, 

-> Could you please add " txchain=1" in the NVRAM file and check if the issue still persist?

-> Does the core 0 and 1 both transmit  with  txchain 2 or 3?

Regards Vivek.

Hi Vivek,

 

I add the following command in NVRAM, and it can transmit the single by main path only, and I will try to modify it from "1" to "2", and check the signal can be transmitted by aux path or not.

rxchain=1
txchain=1
aa2g=1
aa5g=1

One more question, can I adjust the TX power level for this CW test by wl command?

 

Thanks.

Frankie
