A "physical" command line interface using Amazon Dash buttons.

Getting Started

These instructions will get you a copy of the project up and running on your local linux machine. This program can run on any other machine that Node.js supports, and has the libpcap library installed.

Prerequisites

You will need the following things properly installed on your computer.

• Git
• Node.js (with NPM)
• libcap-dev

Installation

• git clone https://github.com/chancebrilz/dash-button-wireless-cli.git
• cd dash-button-wireless-cli
• npm install
• apt-get install libpcap-dev or using another installation method

Running

$ sudo node index.js

Configuration

Add your Dash Button by creating a new variable of DashDutton type using it's MAC address.

var dash_B268 = DashButton('78:e1:03:92:b2:68')

You can then capture button press packets using the following code

dash_B268.on('detected', function() {

    execute('./scripts/test.sh', 'Running test script...');

});

Setup as Service

These instructions are for systemd. Upstart can also be used but only systemd is supported by default. The program folder must live inside the /opt directory for the service to work. You may need to run these commands as sudo if you are not the root user.

$ mv dash-button-wireless-cli /opt/dash-button-wireless-cli
$ ln -s /opt/dash-button-wireless-cli/services/dashbutton.service /etc/systemd/system/dashbutton.service
$ systemctl enable dashbutton
$ systemctl start dashbutton

This will start the service on reboot, and automatically reload the program if it crashes.
