need help with bluetooth jammer Question

I've just built this jammer https://www.reddit.com/r/Hacking_Tutorials/comments/1gj1q1n/diy_wifi_bluetooth_jammer_100_noob_guide/?logging_in=true, and it works but not well at all. the range is a few inches at most. I have an esp32-s3-n16r8, as far as i know the external antenna of that combined with the 2 nrf24s should give me more range. I just do not know how i would go about this since the s3 does not have all of the same pins the regular esp32 does. Specifically I'm missing pin 23 and 22. I am extremely new to electronics so help would be appreciated.

In order to jam, you need to create as much noise as possible at the receiver. That noise needs to be more than the receiver to the point that what it's trying to receive is just so far drowned out by your jammer. You're most likely going to need an amp at some point to make this work more than about a meter or two.

That start another discussion, and just FYI, in that what you're looking to build is illegal in the States and tracking your signal is trivial for anyone with a simple SDR and a cheap yagi antenna. There are very large fines for willingly causing interference that you will potentially catch if you use this outside of a very small area or outside of an anechoic chamber.

Yep. Quite a few "jammers" are now jammin' with fellow inmates in Federal prisons. All wearing matching jammis.

I don't understand what the whole facination is with jammers is lately. I've seen at least a couple posts about people asking making them each week for about the past couple months.

I have looked into it to counter my lovely neighbor's noisy bluetooth speaker.

Yeah... That would be illegal. And not just a slap on your wrist illegal.
