Portable RF Hacking Tool with a Sub 1GHz RF Transceiver, BLE and USB

PandwaRF is a pocket-sized, portable RF analysis tool operating the sub-1 GHz range. It allows the capture, analysis and re-transmission of RF via an Android device or a Linux PC.
 
It removes the ‘standard SDR Grind’ of capturing, demodulating, analysing, modifying and replaying by hand – replacing it with a simple but powerful interface.

 
System Overview

The PandwaRF system consists of two elements: the hardware device and the software controller, either an Android device or a PC. The hardware is a very capable device, tailored for beginners and advanced users alike. Beyond the functionality provided by the Android interface, the PandwaRF can be easily controlled and customised. No need to risk bricking your device or writing in C, the PandwaRF can be controlled by JavaScript, directly on the smartphone. 

  • Capture any data in ASK/OOK/MSK/2-FSK/GFSK modulation from the 300-928 MHz band
  • Transfer the captured data to your smartphone & save/share it
  • Send the captured data in JSON to your own server for post-processing
  • Write your own scripts or use a provided one
  • Transmit
  • Transmit previously captured data or write your own
  • Transmit data from a smartphone or directly from PandwaRF
  • Brute force with a predefined transmission pattern (encoders or devices)
