WARNING!!! JAMMING IS ILLEGAL

WHAT DOES IT DO?

**IT CREATES NOISE SIGNAL TO JAM BLUETOOTH AND WIFI USING NRF24L01 AND ESP32 IN RANGE 2.4GHZ DEVICES , EFFECTS MAY VARY DEPENDS ON DEVICE BLUETOOTH VERSIONS **

`NOT TESTED ON 2.4GHZ DRONE I DONT HAVE ONE BUT IT CAN JAM ONE..... MAYBE?`

REQUIRED DEVICE AND MODULE:

1pc OR 2pcs NRF24

1pc ESP32 NOTE... YOU CAN USE A NANO OR MICRO BUT ESP32 ARE CHEAP ALMOST SAME PRICE AS ARDUINOS...LOL

10UF-100UF CAPACITOR DEPEND ON YOUR NRF

4. 1 DIP SWITCH (OPTIONAL IF YOU WANT TO USE DIFFERENT PATTERN OF CHANNEL HOPPING)

PINS TO ATTACH NRF24L01 TO ESP32

FOR DUAL/TWO NRF24L01

HSPI= SCK = 14, MISO = 12, MOSI = 13, CS = 15 , CE = 16
VSPI= SCK = 18, MISO =19, MOSI = 23 ,CS =21 ,CE = 22

FOR SINGLE/ONE NRF24L01 YOU CAN CHOOSE BETWEEN HSPI OR VSPI

VSPI= SCK = 18, MISO =19, MOSI = 23 ,CS =21 ,CE = 22
HSPI= SCK = 14, MISO = 12, MOSI = 13, CS = 15 , CE = 16

SWITCH PIN (OPTIONAL)

PIN 33 OF YOUR ESP32

ESP32 PINS WHERE YOU ATTACH YOUR `NRF24` AND `SWITCH`

HOW YOU ATTACH CAPACITOR LOOK OUT FOR POLAROITY SIGNS `- +`

UPLOADING CODE TO ESP32

WEBFLASHERINSTALLER FOR EASY UPLOAD CODE ON ESP32 NO NEED TO DOWNLOAD INO FILE (USE CHROME OR MICROSOFT BROWSER)

WEBFLASHER HERE....SELECT WHAT TO UPLOAD VSPI,HSPI OR DUAL AND CHOOSE RIGHT COM PORT

DEMO

TESTED 10 METERS ON BLUETOOTH 5.0 AND WORKS GREAT
TESTED 10 METERS ON NEWER BLUETOOTH 5.3 WORKING DEPENDS BETWEEN THE GAP OF BLUETOOTH DEVICE AND PHONE
- IF YOU WANT BETTER PERFORMANCE YOU CAN ADD 2.4GHZ RF AMPLIFIER

COMPILING USING IDE (IF YOUR NOT USING WEBFLASHER)

DOWNLOAD LIBRARIES YOU NEED AND INSTALL RF24 LIBRARY AND EZBUTTON LIBRARY
DOWLOAD CODE INO FILE

SOME NOTES

NRF24 CAN DO 125 CHANNELS YOU CAN EDIT IT IN CODE

BLUETOOTH CLASSIC 80 CHANNELS

BLE USES 40 CHANNELS

WIFI USES 1-14 CHANNELS
DRONE 2.4GHZ 1-125 SO YOU NEED TO EDIT CODE TO HOPE 125 CHANNELS
YOU CAN EDIT PAYLOAD SIZE DIRECTLY ON RF24 LIBRARY RF24.CPP LINE # 1972
