The ttnctl program can be configured with command line options described in the API Reference, with environment variables or with a configuration file.
Environment #
ttnctl can be configured using environment variables.
The format of these variables is the underscored version of the command line options that can be found in the API Reference, prefixed with TTNCTL_. Environment variables are uppercase. The environment variables shown below are the values needed for local development. If you just want to use the default TTN server, you don’t have to set any variables.
export TTNCTL_DEBUG=true
