Linux BLE permissions

BlueZ needs permission to start BLE scans.

Arch Linux (no bluetooth group, use polkit):

sudo tee /etc/polkit-1/rules.d/50-bluetooth.rules << 'POLKIT'
polkit.addRule(function(action, subject) {
    if (action.id === "org.bluez.Adapter.StartDiscovery" ||
        action.id === "org.bluez.Adapter.SetDiscoveryFilter") {
        return polkit.Result.YES;
    }
});
POLKIT

Debian/Ubuntu/Fedora (add yourself to the bluetooth group):

sudo usermod -aG bluetooth $USER

Log out and back in after.
