Wireless Helper

A lightweight launcher utility for Headunit Revived.

This app acts as a trigger to start Android Auto Wireless on your phone. It automatically detects your tablet running Headunit Revived via NSD (mDNS) or a passive TCP trigger, ensuring a seamless wireless connection experience.

Features

• Auto-Trigger: Fires the Android Auto wireless intent as soon as the Headunit is detected.
• NSD Support: Finds your tablet in the same WiFi network automatically.
• Passive Mode: Waits for a trigger from the Headunit (ideal for Tablet-Hotspot setups).
• Zero-Config: No manual IP entry required.

Known Issues

• WiFi-Triggers on Android 10 (Q) and below: Google has disabled the automatic wireless projection startup for Android 10 and below in Android Auto versions 16.4 and higher. While it still work on newer Android versions, it is currently impossible to trigger projection on Android 10 with recent Google app updates.

Auto-Start Setup

To ensure reliable background auto-start (Bluetooth/WiFi) and a stable connection:

1. Disable Battery Optimization (CRITICAL): Go to App Info -> Battery -> select "Unrestricted". Since this app acts as a data proxy for Android Auto, it must not be put to sleep while driving.
2. Permissions: Grant Bluetooth and Location permissions when prompted.
3. Paired Devices: Select your car's Bluetooth device in the settings.

Automation (Tasker / MacroDroid / ADB)

Wireless Helper supports remote control via Android Intents and App Shortcuts.
