AUTARCH Network Discovery
Advertises AUTARCH on the local network so companion apps can find it.
Discovery methods (priority order):
1. mDNS/Zeroconf — LAN service advertisement (_autarch._tcp.local.)
2. Bluetooth — RFCOMM service advertisement (requires BT adapter + security enabled)
Dependencies:
- mDNS: pip install zeroconf (optional, graceful fallback)
- Bluetooth: system bluetoothctl + hcitool (no pip package needed)
