Firmware Update: Keep Speaker Powered On While Charging (No Auto Power-Off) – Avantree Support

FIRMWARE UPDATE

Harmony A1 – Keep the Speaker ON While Plugged In

By default, Harmony A1 turns OFF after 60 minutes with no audio, even when connected to a broadcast.

After this update:
Plugged into power = Speaker stays ON. It stays ON even when no audio is playing.

Step 1 – Install the Avantree Updater

Download and install the Avantree Updater on your computer. Open it when installation is complete.

Download Harmony A1 Updater

Step 2 – Connect and Update the Harmony A1

Connect the Harmony A1 directly to your computer using a USB data cable.

Important: Some USB cables are for charging only. If your computer cannot detect the speaker, try another cable that supports data transfer.

Follow the instructions shown in the Avantree Updater. Keep the speaker connected until the update is complete.

Do not unplug the speaker during the update.

Step 3 – Reset the Speaker

Turn the Harmony A1 ON.
Press and hold + and − together for 5 seconds.
Watch the MODE LED.

Solid PINK for 2 seconds

Flashing ORANGE = Reset complete

Note: The reset clears the speaker’s previous pairing history and restores Auracast Broadcasting mode. You may need to reconnect the speaker.

Test the New Setting

Connect the Harmony A1 to external power.
Turn the speaker ON.
Leave it plugged in.

The speaker can now remain ON even when no audio is playing.

Something Doesn’t Look Right?

Computer Does Not Detect the Speaker

Try another USB data cable. A charging-only cable can power the speaker but may not allow the firmware update.

Speaker Still Turns OFF After 60 Minutes

Make sure you completed both the firmware update and the + and − reset for 5 seconds. Then test again while the speaker is connected to external power.

Speaker No Longer Connects After the Update

This is expected after the reset because the previous pairing history is cleared. Reconnect the Harmony A1 to your device or Auracast broadcast.
