hi,we are use 43362 as softap,Test transmitting signal,This is shown below:

pastedImage_0.png

In nvram, maxp2ga0=74,softap channel is 1(2412MHz)

2.After observation for a period of time, abnormal waveform was found to be generated, and the abnormal wave power was very large,The figure above shows the maximum holding waveform over a period of time

In dynamic observation, abnormal waveforms appear and disappear immediately

3.The anomalous wave (overpowered) frequency point is also regular, always shifting about 5MHz to the right of the current channel frequency point

4.Please help to check the cause of this problem. I think the 2.4g waveform is not caused by us, but by the chip itself

Looking forward to your reply!

Can you let us know if you obtained the nvram settings from your module partner? If not, can you please contact your module partner for the same? Also can you let us know how you are bringing up the softap? If it is a sequence of wl commands, please share the same.

hi:

I retested withwiced studio the nvarm 6.4 for You provide

It doesn't have a very strong abnormal waveform,But the output power is extremely low, only -2dbm

pastedImage_1.pngpastedImage_0.png

And with the frequency error, I confirm that the test board has no frequency error

Simply because you changed the nvram parameters you provided,Please provide assistance!!!

The NVRAM provided is from WICED 6.4 and meant to be used for BCM943362WCD4 eval kit. If you are using your own hardware, please obtain the nvram settings from your module partner.
