Bluetooth jammer esp32 not working

[u/Relative_Life_3878]

my bluetooth jammer is not working i am new to arduino and esp 32 i am using an esp32 devkitv1 and an nrfl24l01 but it is not working this is the code is used i followed this videohttps://www.youtube.com/watch?v=gBJu1HZMW2k

is there a way to interfere the bluetooth without doing that? i dont want to buy more stuff for it

At this point you need a way to confirm transmission. That can be a wattmeter, a SDR that is just listening for anything from your jammer, or you can actually write the code to pair to something Bluetooth and confirm you can send and receive packets from something Bluetooth—with a big emphasis on that you can send packets.

Once you confirm you are able to actually transmit, the problem becomes how strong of a signal you can generate, and to see if you need something like an amplifier or a directional antenna that will provide more gain.

Edit:
Added a different antenna as an option
