RPi 4 ReSpeaker satellite : work once then no more Wake Word detection :(

mikebzh44 · November 24, 2024, 10:51am

Hello.

I have build a satellite with a RPi 4 and a ReSpeaker card.

I use this tutorial to set up my satellite :

rhasspy/wyoming-satellite/blob/a2bb7c8f57162a2ea5a10b56eb67334f92ff5b8e/docs/tutorial_installer.md

# Tutorial with Installer

Create a voice satellite using a Raspberry Pi 3+ and USB microphone and speakers.

## Install OS

Follow instructions to [install Raspberry Pi OS](https://www.raspberrypi.com/software/). Under "Choose OS", pick "Raspberry Pi OS (other)" and "Raspberry Pi OS (**64-bit**) Lite".

When asking if you'd like to apply customization settings, choose "Edit Settings" and:

* Set a username/password
* Configure the wireless LAN
* Under the Services tab, enable SSH and use password authentication

## Install Dependencies

After flashing and booting the satellite, connect to it over SSH using the username/password you configured during flashing.

**On the satellite**, make sure system dependencies are installed:

This morning, after restarting all services on the RPi :

I was able to turn on a light using voice command :

But after that, my Wake Word is not detected any more. No blue LED on the ReSpeaker to indicate that the wake word was detected.

Any clue or tips ? Is it normal for the Assist to stay in the Responding state ? When doing nothing, the stat shouldn’t be Idle ?
