OpenOmni

This repository contains all the discovered protocols, commands, error types and other messages used to communicate with an Omnipod pump described in the wiki together with many Packet Captures which have been used to find the logic behind each command.

Also provided are the 2 programs used for decoding the Omnipod communications for RTLSDR and RFCAT devices.

Current Status

What you'll need to capture the commands

There are 2 ways you can build a radio capture and parsing setup:

  1. RFCAT Omni

This was the first python based capture program, which parsed the data as raw or as txt. This needs a compatible RF Cat USB stick and has done a great job in capturing, but was expensive because you will need to flash firmware onto it using a CC-Debugger and we later discovered it was missing some packages. Files and Install guide rfcatomni

  1. RTL-SDR Omni

This program was later developped to capture the pure wav files in C which can parsed directly. It can also parse the raw txt data of the RFCAT above. This solution uses an inexpensive RTL-SDR USB stick with an antenna (really needed to get a good recording) as cheaper hardware solution. Files and install guide rtlomni
