Introduction

The most curious concept of Proxmark3 is standalone mode.

If you can power your device from battery, you can run small modules from the PM3 itself, without needing a computer running the PM3 client.

These modules are usually limited to a single function, eg: "read and emulate a Legic Prime RFID tag". This also means the user interface is limited to the LEDs and the button:

LEDS	BUTTON PRESS
4 leds (A,B,C,D)	short, long or multiple (twice)

All standalone modes use this differently, and it is hard to figure out what is what. Looking at the source code for each mode generally helps!

To enter the currently flashed standalone mode, press and hold the button until the LEDs play a short animation.

Warning: all standalone modes that target generic PM3 devices will lose data on power loss (or if the battery goes flat). Standalone modes that take advantage of RDV4-specific features can overcome this by storing data to flash.

Supported standalone modes

For any iceman based repo the current most popular public standalone modes is quite easy to compile and install.

In this repo its even easier than before. The default standalone mode is LF_SAMYRUN.

Warning: some standalone modes takes advantage of RDV4 specific features, which may not work on non-RDV4 devices. You will most likely need to read the source code to understand what is supported.

Installing a different standalone module

The standalone module can be switched in the file Makefile.platform. Only one standalone module can be chosen at a time.

Copy Makefile.platform.sample to Makefile.platform
Edit the STANDALONE variable inside Makefile.platform. You need to uncomment it and chose a standalone mode. For example:
```
PLATFORM=PM3RDV4
#PLATFORM_EXTRAS=BTADDON
STANDALONE=LF_EM4100RWC
```

After changing your standalone mode, don't forget to build and flash the code to the Proxmark3:

make clean
make -j
./pm3-flash-fullimage

Additional information

Some members of our community have produced text and video walk-throughs of these modules:

@Hacker warehouse did a nice video on youtube.
Troy also has a nice image of the leds for LF_SAMYRUN.
TinkerSec blogged about HID Prox badge cloning.
quentynblog made a video about the HF_TCPRST (IKEA Rothult) standalone module.
