How to Make a Bluetooth Jammer

[@barth7204]

thank you from america latina, we need this device so we can sleep properly at night

[@EngineerNotFound]

I've been curious about where these might be used in public in and around my city. A few years back I lived in an area where, every time I walked past a specific section of the road past a certain set of houses on my way to pick up some groceries, my bluetooth would cut out. I first thought it was a coincidence but it happened every time I went past that particular spot, so I believe it was either one of the houses, or one of the small businesses nearby. I even changed my route a bit to avoid it because not only did the bluetooth drop, but I had to disconnect the ear buds and reboot the phone to get it working again; really stringe. I've noticed it happens in a few other public areas on my travels, in particular spots, and I've always wondered if somebody is using a jammer in that spot. Anyway, pretty interesting project.

Thank you from Brazil

Can I use esp8266 nodeMCU instead of esp32

[@DivineZeal]

No just be esp32! Esp8266 is much weaker

[@larrybud]

I think it'd be helpful to talk about the circuit and code and how this works.

[@DivineZeal]

Yes I am going to make a more in-depth video. I have the custom pcbs coming next week!

[@Maksimilijann]

hey, thank you for sharing, how long is the distance would be with this?

[@DivineZeal]

Thanks for watching! I haven’t tested the max range yet, and I’m waiting on new antennas, but current can get about 10-20yards through some walls so I’d imagine it’s pretty good

[@lpadron13]

I'm a compete novice. What do you suggest as a starting point for learning about boards, soldering and all the rest? Thanks!

[@DivineZeal]

I’d suggest starting with an UNO board like the esp32-s3 UNO. It’s super easy to use and a great place to begin. There are tons of awesome tutorials and resources available on Adafruit Learn, especially for beginners. When it comes to soldering, start with simple projects and don’t be afraid to experiment and make mistakes. That’s all part of the learning process!

[@lpadron13]

@DivineZeal thanks!

[@zemarcelo8]

hi, great job! 2.4 frequency also interfere in wireless and UHF microphone?

[@DivineZeal]

Anything with 2.4ghz frequency , you will need to check your devices

[@JUHANSTUDIO]

Will the 2.4 frequency also interfere? (WiFi)

[@DivineZeal]

Yes WiFi is channels 1-14, Bluetooth 1-80, and drones 1-125

[@gustavoreges163]

can i use display in this ESP?

[@phamaral249]

what's the range of this?

[@DivineZeal]

10-30+ meters depends on your antennas. I don’t use the stock antennas

[@korosenai4295]

Can you make a tutorial for the jumper cable

[@DivineZeal]

Yes I am going to make a more detailed video with the cables and soldering!

[@marka.2715]

What is the range on this device?

[@DivineZeal]

The range for me is least 30 meters, however I use stronger antennas than the stock, about 9dBi

[@DeltaLeakz]

May i ask? Can i use a ceramic capacitor ?

[@DivineZeal]

Yes go for it

[@evandrovitorino9108]

Could you post the link to the project with just one NRF24 antenna. + ESP32

[@DivineZeal]

You can use the non DUAL .ino files here github.com/dkyazzentwatwa/cypher-jammer/tree/main/smoochie_version

[@hysavuthchanchesda2544]

Is the capacitor effect the range? Becuz i use 50v and 47uf and seem like it work only 1-2 meter

[@DivineZeal]

You need better antennas. Find 9+ dBi 2.4ghz antennas

does it disconnect the device? and what does it do to wifi?

[@DivineZeal]

It stops the device for transmitting data, doesn’t disconnect. You change the channels in code to target WiFi or Bluetooth

[@woy73]

do I have to use nrf240l like that, I bought ( NRF24L01 Ultra Long Range 2100M E01-ML01DP5 Ebyte 20dBm 2.4Ghz +PA+LNA), can I use this Sorry, my English is bad

[@DivineZeal]

Yes it will work. If it doesn’t work good you will have to add a 10uF 50V capacitor like I did

[@woy73]

​@@DivineZeal terimakasih banyak, saya sudah berhasil membuatnya

[@វុយហេងសេង]

I still dont understand sir can you make from begining wiring please 🙏

[@anta777-k6x]

Is it possible to use 3?

[@DivineZeal]

Yes I have a project with 3 coming really soon but it is more complex. I have the custom pcb that will be easy for people to make

[@anta777-k6x]

@@DivineZeal The problem with me is that none of these companies makes deliveries to my state

[@rogerroach3250]

Can i use 100uF instead of 50uf for NRF24L01?

[@DivineZeal]

I am using 10uf 50V which is good enough. Anything more than 10uF is perfectly fine, but 100uf is overkill. If the capacitor size doesn’t bother you then go for it! Also a larger one may take longer to charge/discharge but I dunno if you’d notice

[@rogerroach3250]

Can I do with esp8266 and nrf

[@appengrayhan1604]

esp8266 doesnt have bt

[@helenmachelen4200]

Cool, thanks. Looking forward to 5 and 6ghz version 😉

[@DivineZeal]

5GHz version video out now. I am also about to release the 5GHz device with display and buttons! Thanks for watching

[@pablobalcazar1616]

Nice vid I already bought everything to make mine. Help us with the pinouts on where to solder, please

Can I ask for the bin code for 2 NRFs, I tried uploading with ArduinoDroid, it always gives an error, (Guru Meditaion error), now I only use 1 NRF

[@Dgorbatko]

Hi, I have a M5stickc and nrf24 with custom firmware. So jamming is working there, but I want to try dual nrf24 as you did. So did I understand correctly that I need to connect second nrf24 in parallel to the first nrf24 to make it works and makes noise signal stronger?

[@DivineZeal]

Yes it is best not to cross antennas. If using multiple, the nRFs can share the same SPI bus, just have different CS + CSN pins

[@Dgorbatko]

⁠@@DivineZealI realized it’s unreal to connect two nrf to m5stick because I have only 5 gpio pins +gnd and 3v. So all 5 pins are taken by one nrf, so there is now way to connect the second one, even if I share one spi bus then I anyway need to have two extra free pins. The only one way is to connect second nrf exactly to the same pins on m5stick. But I’m sure it wouldn’t work or there won’t be any difference between one nrf or two parallels nrf. What do you think?

[@mauricieo222]

What's the maximum reach?

[@DivineZeal]

With walls it can do pretty good, but without walls I’m guessing 50M-100+ meters. Especially if you swap the stock antenna. These are same antennas used for rc drones… so as high as the sky lol

[@Necoronics]

I did it correctly but it's not worked, what is the problem you think? Nrf pins:0

[@DivineZeal]

You must 100% make sure pins are correct

[@arminferdinand5849]

Alright now my neighboors gonna chill

[@Sam-l7b5z]

Can i use esp32 wroom 32d instead of 32e? And without amplifier and with 9dbi how long can it support?

[@DivineZeal]

Yes, of course. You need amplifier though for best results. You can even source your or stronger amplifier

[@Sam-l7b5z]

@DivineZeal thanks for the reply

[@smoochies5056]

use noisyboy repo...

[@DivineZeal]

SMOOCHIES!! YES I will! Love your work, I have been wanting to try noisyboy.

[@VidVid-s3u]

Hey man thank you for sharing do you have a full tutorial ❤

[@marknagy7549]

does it work with arduino nano?

[@DivineZeal]

No because it uses ESP WiFi libraries . The esp32 is as cheap as an Nano

[@MR.ROMEOTECH]

How to make this totorial please

[@Marranrageh]

Guys it worked 😁😁

[@DivineZeal]

Yesss I’m happy for you!!

[@agnunez77]

Hello from Argentina, I'm wondering how the range can be improved with capacitors with other specifications? Thanks

[@DivineZeal]

Can be increased with better antennas and good line of sight. Capacitors help decouple and with power surges, not too much range. I use 9-12dbi antennas from AliExpress. You can also make your own. Also if you are creative try adding more amplifiers and better power source

[@PetrBelohoubek-ot5ok]

cool tut

[@ouksotheara]

how far?

[@DivineZeal]

So far I’ve got about 10-20+ meters but that’s with walls. I have some different antennas I want to try with the nrf24 so should be way more. The nrf24 claims to have like 100-1000M

The only reason im watching this is bcz i need this in future

[@DivineZeal]

Great hope it helps!

[@Miqa-f7o]

What is the max distance on this

[@DivineZeal]

Depends on your antennas but with my 9dBi antennas I get atleast 10-30+M with obstructions
