Overview: Wi-Fi to Bluetooth Audio Bridge

Laptops and PCs holding your music collection are often located away from your living room soundbar or car stereo. RideStream bridges the gap: your phone receives lossless audio over home Wi-Fi and outputs it instantly to your Bluetooth speakers or car audio system.

Step-by-Step Assistant: Setting Up Bluetooth Audio

  1. Pair your Receiver Phone to your Bluetooth Audio System:

    Turn on Bluetooth on your Android phone and pair it with your car stereo, soundbar, or Bluetooth receiver in Android Bluetooth settings.

  2. Connect to Host PC over Wi-Fi:

    Open RideStream on your phone, tap the Cast Icon 📡, select Receiver Mode, and pick your PC host server.

  3. Enable Audio Normalization:

    In RideStream settings, make sure Audio Normalization is enabled to avoid sudden volume spikes when switching between songs.

  4. Start Playback:

    Select any mixed playlist from the server. Music plays through your Bluetooth speakers, and track info metadata is displayed on your car stereo dashboard.

Steering Wheel & Media Button Support (AVRCP)

RideStream integrates with Android's MediaSession framework. You can press Next Track ⏭️, Previous Track ⏮️, or Play/Pause ⏯️ directly from your car's steering wheel buttons or Bluetooth headphones to control the stream queue.

⚠️ Hands-free only: Depending on your local laws, operating a handheld device while driving may be illegal. Pair your phone and start the stream before you start driving — then use only the hands-free steering-wheel controls while at the wheel.
💡 Background Audio Playback RideStream runs as a Foreground Service. Music keeps playing without interruption even when your phone screen is locked or when using GPS navigation apps like Google Maps or Waze!

🔧 Troubleshooting Bluetooth Audio

❓ Song Title Not Showing on Car Dashboard Display?

Ensure your car stereo supports Bluetooth AVRCP 1.4 or higher. Re-pair your phone in car Bluetooth settings and select "Media Audio" permissions.

❓ Audio Mutes When GPS Navigation Speaks?

RideStream respects Android audio focus standards. When Google Maps or Waze gives a voice direction, RideStream automatically lowers (ducks) the music volume and restores it smoothly when navigation finishes.
