A tool which jam classic bluetooth signals.

• Minimal Setup.
• On/Off by GPIO pin.

• NodeMCU ESP-32S V1.1 38-Pins
• One nrf24L01 Module OR nrf24L01+PA/LNA Module
• 8 Female to Female Jumper Wires

• nrf24L01 and nrf24L01+PA/LNA modules have same pinout.

• Connect one end of wire to GPIO12 and other to GND.
• If it is shorted, the jammer is working otherwise not.
