Software

• NixOS based SD card images generated from following repository
• Repository - https://github.com/sorki/nixpkgs/tree/ttn_dev
• Gateway configuration example - https://github.com/sorki/nixpkgs/blob/ttn_dev/gw.nix
• Packet forwarder configuration example - https://github.com/sorki/nixpkgs/blob/ttn_dev/gw.nix#L60
• Script to build SD card images (requires nix) - https://github.com/sorki/nixpkgs/blob/ttn_dev/gwgimme

Currently all gatewayas use legacy packet_forwarder which will be replaced by kernel space driver in future.
