I found this project while trying to set up a wifi/bluetooth audio receiver to play pandora on my older hi fi setup… I had a Raspberry Pi Zero W with a HiFiBerry DAC+ Zero laying around so I gave it a shot.
Setting up the applicaion on Balena’s site was easy and straight forward, I built the application with the latest production version
flashing the SD Card was exactly as expected
The RPi booted as expected
The RPi was discovered on the control panel
I grabbed a copy of the latest project files from GitHub
Using the CLI I uploaded the project files to the application
watching the control panel Airplay, bluetooth audio, fleet supervisor, Snapcast client and spotify all pushed to the RPi and went to a running state. Snapcast server pushed but is in a stopped state.
To be safe I rebooted the RPi, I get a solid green light on the RPi, The RPi shows up in the control panel
I edited the RESIN_HOST_CONFIG_dtparam variable to set ”audio=off”
and added the variable BALENA_HOST_CONFIG_dtoverlay with a value of hifiberry-dac
now comes the issues…
The RPi doesn’t show up as an availalbe bluetooth device on my phone
looking in the control panel online and watching the logs there are a bunch of errors showing up

I have rebuilt the application at least 6 times using a combination of the latest builds of the OS and the project files, both in prod and dev. I have tried 2.48, 2.46, and 2.32 OS versions and project file versions 2.2.1, 2.2.2, and 2.2.3 (master)… I have tried all 3 OS versions in Dev and Prod.
I am really hoping someone on here has some suggestions on getting this working.

EDIT:
i saw someone else post that Wifi was interfering with Bluetooth on their RPi… so I just rebuilt with latest OS and project files, configured with Ethernet only, booted with USB Ethernet adapter, and am seeing the same issues
