NRF700X wifi beacon scrambler seed

[JasonJ]

Hi, I am having issues with one of our wifi scanning modules not detecting the wifi beacon using the 1M rate. Looking into the PHY level, I demodulated different wifi beacons and only the NRF700X had a different scrambled preamble. It seems the NRF700X isn't using the specified scrambler seed according to this section of the wifi spec.

Can you confirm?

Is this something that can be fixed with a software update?

Regards,

Hi Jason,

Thank you for bringing this issue to our attention.

I will forward it to our development team for further investigation and will get back to you as soon as I have more information.

Best regards,

Hi Jason,

To better understand your issue, could you please clarify the following:

1. What specific pattern are you observing?
2. What chipset are you using in your scanning device?

These details will help us investigate further and provide more targeted assistance.

Best regards,

Charlie

Hi Charlie,

I would just like for you to confirm the scrambler seed (from the IEEE standard 802.11 clauses 16 & 15, see original image) used by the nRF700X when beaconing at the 1M rate.

Hi Jason,

According to our development team, the current scrabler seed is 0x5a and can be fixed with the firmware update. Could you please send us the NCS version so we can provide the fix?

on the issue, the Receiver is expected to demodulate with any scrambler as per the spec

Best regards,

Charlie

Great, I am using NCS v2.8.0.

Yes, we are looking to get it fixed on the receiver side as well.
