[HackRF - Help with 2.4 GHz Signal Registration]

Thanks.

 

I think I have got some clues. Ubertooth One would be a nice thing to have, but it costs quite a bit (in addition to HackRF that I already have). 

I think I will try NRF24LU1 to start with. Maybe it will catch the signal differently. Those RF dongles that receive the signal from the remote control are really small to be able to do many manipulations, and they all work really good. Very rarely happens that a press of the button will not go through. So, there must be something that could filter out most of the noise. would that be the exact frequency, sending sync on several channels. i guess I will have to figure that out.

I have 3 remotes/devices that work on 2.4Ghz frequency with dongles and I have hard time registering signals with HackRF on all of them.

Here is one example (not the one in the first posting):

Measy RC12 remote control with keyboard and air mouse.

https://fccid.io/RB8RC12

https://fccid.io/RB8RC12/Test-Report/RF-Test-Report-1868274

Frequency: : 2402-2480MHz   
Modulation : FSK    
Number of Channel  :  157 Channels 
Frequency Separation  :  0.5MHz   
Antenna Type  :  Integral   
Antenna Gain  :  0 dBi 

any idea how to make HackRF registering a strong signal for that?

Thanks.

Thanks.

I tried to find  the FCC or EC registration number, but could not find it.

I think I will try it with another remote control that has EC certification and uses RF 2.4GHz signal and see if I can go from there.

Hi.

I am trying to analyze the signal that is going

    from a 2.4 Ghz RF remote control

    into the TV that has a USB port with a dongle connected

I could find the frequency and could see in in SDR#

but the signal is too weak, even if I hold the remote next to HackRF's anthenna, and sometimes it does not register the signal at all. The TV is 4 steps away and registers the signal every time.

the remote has Beken BK2535 DH650QS chip in it:

What am I doing wrong? Is there some setting that needs to be adjusted?

Thanks a lot!
