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
and added the variable
BALENA_HOST_CONFIG_dtoverlay with a value of
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.
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
