🖼️ Wifi Display Networking Setup

Bluetooth GATT Server to accept Wifi Credentials

Develop

If you're on NixOS, run direnv allow once in the project's root directory. From then on, the development environment will be initialized as soon as you cd into the project's directory. Alternatively, you can run nix develop manually. Now you should have the correct version of Rust, pkg-config, etc. in your environment.

1. To run a development version of the project:

cargo run

Build

1. To compile a release version of the project for your x86_64 host machine:

nix build .#wifi-setup

# Alternatively
nix build

2. To cross-compile for aarch64, i.e. a Raspberry Pi

nix build .#wifi-setup-aarch64

Deploy

To deploy the project on a Raspberry Pi, you'll need the following items:

• A systemd service (see systemd/wifi-setup.service)
• Bluetooth packages installed (bluez and bluetooth)
• The binary compiled for aarch64 (see above)

Alternatively, on NixOS you can use the deployment script found in the flake.nix. This will build the binary, copy it to your target and create the systemd service there for you.

nix run . -- [email protected]

Debug

On the Pi, you can check the logs of the service

# Check status
sudo systemctl status wifi-setup

# Follow logs
journalctl -u wifi-setup -f

In addition, you can check the status of the Bluetooth device and underlying software.

# Open interactive bluetooth repl
sudo bluetoothctl
show
power on # If powered off, turn on the bluetooth device
