[Hackrf-dev] Signal Interference at 2.4 GHz using HackRF and SDR#

[Srinivasan T]

Hi Mike,

The interference affected the entire 2.4 GHz channels.
Please let me know about 10 Hz beaconing ?

I have wifi signal analyzer, and it fluctuates to -10 dBm

Cheers

Srinivasan T

Pic 2 looks like fairly normal packets, to me.  Your waterfall refresh rate
is probably too slow to catch the 10hz beaconing.

Pic 1 could be heavy wifi traffic and you're looking at the gap in 2
channel.
