I have a speaker connected to my Raspberry pi 3B+ with balena OS for multi room. I was wondering if I could make my application a wifi network and connect to my device/devices through wifi and play music through the devices network connection.
If you are familiar with docker you could combine it with this other project we have: https://github.com/balenalabs-incubator/wifi-repeater
With that project you can turn your device into a WiFi hotspot basically. That will leave your device offline so if you want it to connect to balenaCloud and in general have internet access you’ll need to provide internet via ethernet cable.
