Frequently Asked Questions

Why does my Bluetooth speaker keep disconnecting?

Most Bluetooth speakers have a power-saving feature that automatically disconnects after 10-15 minutes of silence. Bluetooth Keep Alive prevents this by playing an inaudible signal that keeps the Bluetooth audio stream active.

Will I hear the keep-alive signal?

No. The default "Silent Tone" mode uses a 1 Hz frequency that is far below human hearing range. You can also add optional background noise (pink, brown, white, rain) at any volume level for comfort.

Does it work in the background on phones?

Yes. Bluetooth Keep Alive uses advanced browser APIs (Media Session, Web Locks) to keep running even when you switch apps or lock your phone. For best results on iOS, keep the browser tab active.

Will it drain my battery?

Bluetooth Keep Alive is designed for minimal CPU usage. The silent tone mode uses almost no processing power. For sessions longer than 2 hours, we recommend plugging in your device.

Can I use it with my car Bluetooth?

Absolutely. The "Car Bluetooth" preset is specifically designed for car Bluetooth systems that disconnect when there's no audio playing. Just start it before your drive.

Does it work with Bluetooth headphones and earbuds?

Yes, it works with all Bluetooth audio devices including headphones, earbuds, AirPods, Galaxy Buds, hearing aids, and any other Bluetooth audio receiver. It also works with HDMI and wired connections.

Can I download the Bluetooth keep-alive signal as a file?

Yes. Use the "Download Bluetooth Keep-Alive File" section to generate an MP3 or WAV file. Play it on repeat from any music player to keep your Bluetooth device connected, even without internet.

Is it really free?

Yes, Bluetooth Keep Alive is completely free with no registration, no ads, and no limits. Runs in your browser via Web Audio API.
