BLUNO Question

Good day,
I bought a BLUNO recently but didn't quite notice that there is a minimum requirement to be able to use it properly. It says that you should have Android OS 4.3 or higher and Bluetooth v4.0. So since I have a Samsung S3 Mini but cannot update the OS so I'm stucked with 4.1.2 OS. Currently Samsung doesn't have update for my phone for 4.3, so is there a work around solution on how I can work with my phone without updating the OS?
