I'm currently running HiFiBerry OS on the raspberry pi 4 right now and I'm planning on building a sort of bluetooth speaker based on this platform.
Out of the gate, it looks like the bluetooth pairing process can only be started from the WEB UI in HiFiBerry OS. I. For the project I have in mind, it seems a bit cumbersome to first go to the Web UI to start bluetooth discoverability. How are others treating this process? I do have the option to put a button on my box to start the pairing process if needed, but is there an easy way to start the process by input from the GPIO pins?
The 'Interact'-functionality might be useful, but doesn't seem to allow for GPIO input (and I really don't want to work around this by using serial). What are my options here?
