Incorrect Preamble 123

[Edward13ruf]

I am trying to run the container (ghcr.io/ohf-voice/linux-voice-assistant:1.1.11) using docker compose as a starting point. I believe I have done everything correctly and the system logs look okay until I try and connect Home Assistant to it.

Home assistant tries this a few times before reporting that is Failed to Connect. I am not at the point of testing the application and audio components yet, this was just about making sure that the system could connect to Home Assistant first.

I had the same problem, however, that "incorrect preample" error vanished after pressing the "retry" button in HA.

However, now it does not recognize any wakeword. Well, another issue. Lets see ...

Ok, offtopic, but restarting the satellite another time also made the wake word work. I'll stop here for my part.

I'm getting the same error, only with Incorrect Preamble 71 when I try to establish a websocket connection from python (the snippet from the examples), or with the console example from https://github.com/OHF-Voice/linux-voice-assistant/blob/main/examples/Peripheral%20web%20console/DOCS.md

AI tells me (unverified) that's because of a GET request (71='G') trying to upgrade the protocol to websocket.

EDIT: Nevermind, my bad. I tried to connect to the API_PORT, and not the port of the PERIPHERAL_API.
Due to a number of reasons. I pulled the latest image, which does not have the peripheral api yet. As the connection didn't work, trying to identify the problem, I mistook the API_PORT env as the port for the peripheral api and tried to connect to this.
With this, the websocket then obviously tried to connect to the ESPHome API, resulting in the error.

Using the nightly image resolved my problem.

Can you run the latest version (1.1.13) now and say how is it going?
