Why if I transmit in 2.45GHz with my hackrf, Bluetooth connections don’t have any noise?

Bluetooth connections are in 2.45GHz, so theoretically if I transmit in 2.45GHz some stuff, bluetooth connections should have at least some noise, but it doesn't happen.

I know that exists "Frequency Hopping", but why audio don't have any noise at all?

Use an SDR to measure TV antenna performance?

I was wondering if you can use an SDR to measure TV antenna performance. I am wondering because I have a NooElec NESDR and want to add a rooftop tv antenna to our condo building. There is an old analog antenna that has rusted away already there. So cables likely won't need replacing but the other end of the cable that connects to the amplifier is several floors down. So I wonder if I can use my SDR to measure performance when pointing the antenna and look at the results on my laptop on the roof.

Also I wonder how well the old analog amplifier will work with the digital signals. I know they make more efficient amplifiers for digital since it doesn't quite need as much juice but they are quite expensive for 30+ units of amplification. So re-using our old one would be awesome.

Does anyone know any method of doing this? Thanks!!

in the screenshot
Which?
I personalty gave up to decode anything beside of Audio the chance to receive it clear enough is very low.

Well that is going to be a bit more complicated. I'll try and capture the pairing process and see if there is a seed number that used as part of the rolling code generation.

But my question still stands about interpreting the data in the screenshot. Am I correct in identifying the digital signal?

Would a fireplace need to use a rolling code?
To avoid:
a) when 2 people use the same System to not disturb them
b) for security think

its common in Europe.
Do I need to duplicate pairing functionality?
You need to Hack the System and read out the Codes.
Good Luck... There is be easy to design your own Remote Control System.

Would a fireplace need to use a rolling code? Seems like over kill for something that does not provide access.

If indeed this is the case, how do I design for a rolling code? Do I need to duplicate pairing functionality?
