Part Number: CC3220

Hi. Experts.

I tried ping test using Huawei AP(HG8245H) and CC3220SF.

However, it was confirmed that the loss rate was 18% or more.

So I would like to modify the A-MPDU and LGI, SGI parameter and test again.

Is it possible to set A-MPDU ON, LGI(Long Guard Interval) and SGI(Short Guard Interval) in cc3220sf?

Hi IK,

There is no user control over these parameters.
The SimpleLink network processor takes the decisions internally.

Hi Kobi,

Thank you for reply.

I have one more question.

Can you tell what the initial values of AMPDU, LGI and SGI are?

Hi IK,

There is no meaning to the initial values.
The values are constantly being updated with other parameters (such as TX rate) according to internal channel assessment done by the rate management logic inside the NWP (this is based on RSSI, SNR, PER and other indications).
