3) Webpanel

• Connect your mobile/laptop/computer to this Wi-Fi:

SSID: ECRF
Password: 123456789

• Open a browser and navigate to the web panel. (Default IP: 192.168.4.1)

• Enjoy

4) Rolljam Firmware

• Download and upload Rolljam firmware on your second device.

The first device must be powered ON and connected to the default ECRF network. (SSID: ECRF | Password: 123456789)

• Plug your second device into your computer and get the IP address from the serial monitor. (Baudrate: 38400)

• Go to the EvilCrowRF web panel and set the IP address of the second device. (ECRF Settings -> Jammer Device -> Local IP Address)

• Now you can start a rolljam attack.
