# flipperzero-lrs-pagers
FlipperZero Brute force of LRS Pager System from [JimiLinuxGuy](https://github.com/jimilinuxguy/flipperzero-lrs-pagers)
Only the 433 version works in all released firmwares (though it may not work for most/any pagers.)<br>
For the standard 467 version, you'll need to modify the Flipper firmware. See warning below.
This should brute force all resturaunt IDs and pager ids and alert/beep each one for 30s. Verified that this works at Chilis.
Officially supported frequencies: 300-348 MHz, 387-464 MHz, and 779-928 MHz (from [CC1101 chip docs](https://www.ti.com/product/CC1101))<br>
Unofficially supported frequencies: 281-361 MHz, 378-481 MHz, and 749-962 MHz (from [YARD Stick One](https://greatscottgadgets.com/yardstickone/) CC1111 docs)
No mainstream firmware (Official, Unleashed, or RogueMaster) currently allow anything outside of the officially supported CC1101 specs.
**NOTE: Going outside the supported frequencies may DAMAGE YOUR FLIPPER AMP.<br>
Please understand what you're doing if trying to break out of official frequencies.**
You'll need to edit some code and recompile if you want to break outside of the officially supported frequencies. ([Hint here...](https://github.com/flipperdevices/flipperzero-firmware/pull/1287/files))
