This repository enables you to prototype an Alexa Gadget using Raspberry Pi. It includes Python-based software, sample projects, and step-by-step instructional guides that walk you through how to use key features of the Alexa Gadgets Toolkit to create new, engaging customer interactions with gadget devices.
Essentially using Kitchen Sink with an overridden load/save of the .agt.json (as I needed it to be stored elsewhere) inside a Docker container with network_mode: host and everything needed for Bluetooth to work
(Log at the bottom)
It pairs initially and all works fine, I get directives, the .agt.json gets saved (to /data/agt.json) and that can be seen that it does save as it tries to reconnect when the script starts again
But for some reason it adamantly refuses to reconnect (just keeps trying with no luck). I also tried reconnecting in this state from the Echo without any luck either.
Logging level is set to DEBUG too, no helpful debug entries to be seen.
Under what circumstance would this occur? Is it possible the bluetooth address is changing or something stupid like that?
EDIT: Bluetooth address doesn't change and is consistently B827EB543E53. Is there standard bluetooth pairing information being handled outside the script that I might need to make persistent? I'm not overly familiar with Python + Bluetooth...
EDIT2: Found /var/lib/bluetooth with a bit of tinkering with a "Changed in the last minute" command, after binding it to a volume everything now works as it should. I should have experimented a bit more before posting an issue but I hope this helps anyone who wants to do an AGT project within Docker (and possibly Balena which I'm using) as it's a bit of a niche mixture.
For anyone who has the same problem: Essentially you just need to make sure you persist the .agt.json and keep /var/lib/bluetooth as a persistent volume and you're good. network_mode: host also needs to be set so highly recommend doing this via docker-compose.yml if you're using Balena.
