The Things Network Stack

The Things Network is a global open crowdsourced Internet of Things data network.

Getting Started With The Things Network

When you get started with The Things Network, you'll probably have some questions. Here are some things you can do to find the answer to them:

• Check out our website
• Read the official documentation
• Register on the forum and search around
• Join Slack and ask us what you want to know

Installing and Running The Things Network Stack

Although we're all about building an open, public network, we understand that some people rather have everything privately on their own servers. On our website, you'll find some articles describing how you can set up a private routing environment and how you can deploy this environment using Docker.

Development

First, you'll have to prepare your development environment. Follow the steps below to set up your development machine.

1. Make sure you have Go installed (recommended version 1.11, version 1.8 or later is known to work).
2. Set up your Go environment
3. Install the protobuf compiler (protoc)
4. Install make. On Linux install build-essential. On macOS, make comes with XCode or the developer tools. On Windows you can get make from https://gnuarmeclipse.github.io/windows-build-tools/
5. Make sure you have Redis and RabbitMQ installed and running.
   On a fresh installation you might need to install the MQTT plugin for RabbitMQ.
   If you're on Linux, you probably know how to do that. On a Mac, just run brew bundle. The Windows installer will setup and start RabbitMQ as a service. Use the RabbitMQ Command Prompt (sbin dir) to run commands, i.e. to enable plugins.
6. Declare a RabbitMQ exchange ttn.handler of type topic. Using the management plugin, declare the exchange in the web interface http://server-name:15672 or using the management cli, run rabbitmqadmin declare exchange name=ttn.handler type=topic auto_delete=false durable=true. If your handler's user has sufficient permissions on RabbitMQ, it will attempt to create the exchange if not present.

Next, you can clone this repository and set up the TTN part:

1. Fork this repository
2. Clone your fork: git clone --branch develop https://github.com/YOURUSERNAME/ttn.git $GOPATH/src/github.com/TheThingsNetwork/ttn
3. cd $GOPATH/src/github.com/TheThingsNetwork/ttn
4. Install the dependencies for development: make dev-deps
5. Run the tests: make test
6. Run make build to build both ttn and ttnctl from source.
7. Run make dev to install the go binaries into $GOPATH/bin/
   • Optionally on Linux or Mac you can use make link to link them to $GOPATH/bin/ (In order to run the commands, you should have export PATH="$GOPATH/bin:$PATH" in your profile).
8. Configure your ttnctl with the settings in .env/ttnctl.yml.dev-example by copying that file to ~/.ttnctl.yml.
9. Trust the CA certificate of your local discovery server by copying .env/discovery/server.cert to ~/.ttnctl/ca.cert.

You can check your ttnctl configuration by running ttnctl config. It should look like this:

  INFO Using config:

         config file: /home/your-user/.ttnctl.yml
            data dir: /home/your-user/.ttnctl

         auth-server: https://account.thethingsnetwork.org
   discovery-address: localhost:1900
           router-id: dev
          handler-id: dev
        mqtt-address: localhost:1883

NOTE: From now on you should run all commands from the $GOPATH/src/github.com/TheThingsNetwork/ttn directory.
