Hackrf

I loosely based this project off of previous work by SophSec. It's a work in progress, some things will inevitably break. Feel free to contribute!

Before you can start using this gem, you'll need to install libhackrf:

$ sudo apt install libhackrf-dev

Add this line to your application's Gemfile:

gem 'hackrf'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install hackrf

Basic usage is simple:

require 'hackrf'

HackRF::Device::Radio.open do |hackrf|
  info = HackRF::Device::Info.new(hackrf)
  puts info.board_id
  hackrf.frequency = 433.0 * (10 ** 6)
  hackrf.sample_rate = 44.8 * (10 ** 3)

  hackrf.rx do |transfer|
      puts transfer.buffer.dump
  end
end

This library makes use of FFI bindings to the libhackrf API, so the official documentation should prove useful.

After checking out the repo, run bin/setup to install dependencies. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
