[my opinion, which does not contribute ... What is it nowadays with everyone wanting to stream audio over Bluetooth? I don't like this solution. Pairing-state is always uncertain, the whole 'does it work'? No? Repair, etc etc /opinion off]
Sorry can help you with Bluetooth; this is not QLC+ related.
You have to configure your GPIO's as input, because default they are output. That has to be done system wise -> look for that topic in the provided .pdf.
Then you have to make sure that you use a pull up (or pull down) resistor in your circuit. Just using a switch, you go from 'unknown' to ground or high. You need a thru transition from high to low (or vice versa) before signals are read correctly.
First make sure you got the hardware right. (I used a programming tool for students to verify the true state of the GPIO's on another image-build BEFORE I started with the QLC+ image.)
Once you got this figured out, the programming will be a quicky.
