jamRF is a tool used to jam RF it's in the name, duh Sub-Ghz frequencies
You will not be able to start jamming if the selected frequency is not available to the Flipper. I recommend using a CFW that unlocks all frequencies before using.
Select your frequency with the < and > buttons, then press Ok to start jamming.
Caution
Jamming for a long time may damage the CC1101 inside of the Flipper, please use with caution.
Note
The range of the flipper zero's built in antenna is ~20ft for low power jamming. Add an external CC1101 for more range, the app will automatically select it if it is properly configured within the firmware.
Warning
I cannot emphasize this enough, Use this app responsibly. Unauthorized RF jamming is illegal in the U.S. and may lead to fines or criminal charges.
