Soon enough, I had the necessary functionality to control my receiver from the terminal. PicocliĪdding the picocli library to the mix helped out with making my program a little more command-line friendly. So I resisted the urge to further extend this journey by exploring better suited alternatives and instead tried to remember the ins and outs of Socket, PrintWriter, InputStreamReader, and friends.
It’s been a long time since I did much socket programming, and last time I did, it was in Java. It might seem an odd choice, writing a CLI in Java. A quick web search failed to bring up the specification for this API, but it did find a specification of something called the Denon AVR control protocol - basically a text-based API to interact with the receiver over port 23. An API with about as much aesthetic appeal as the GUI itself. Firing up the browser’s Web Developer console and issuing a few commands by manipulating the GUI reveals an HTTP API. But where there is a GUI, there must be an API…Īrmed with that API we should be able to write a simple CLI to control the receiver from the command line. Yeah, so I’m obviously not going to use that. The user interface is pretty much as delightful as you’d expect, pictured here for your viewing enjoyment. The receiver in question, a Denon AVR-X2100W, is not exactly the latest and greatest, but it connects to the local network and comes with a built in web server and a simple GUI. This application is not affiliated with Denon. Denon is a registered trademark of D&M Holdings, Inc.This should be easily solved if there just was some kind of programmatic API available. Send me bug reports, general feedback or feature requests via email or just share your layouts.įor XML serialization the Simple XML serialization open source library is used in this application. If you like this app, please leave a comment. It is tested with the AVR-3312 model only, protocol commands must be adapted to your model eventually.

This is my first Android project so use on your own risk ). The app uses INTERNET, ACCESS_NETWORK_STATE, WRITE_EXTERNAL_STORAGE permissions to connect to the receiver (when on WiFi only) and to store/manage XML layout files on local storage.
You have to set the ip address manually in the settings but therefore it is quite snappy. Its best to use the app with a static ip address for the receiver since there is no automatic recognition.

On how to do this, take a look at this tutorial. You can create your own remote control button layouts with XML files. Remote control your Denon® AVR via local network. Important Notice: If you want to support my work on this project consider buying the Hotspot Starter App.
