Actually, I managed to get it to work, thanks to this thread and the author (It only applies to the H5 SoC from what I know..) https://forum.armbian.com/topic/9043-rtl8723bs-bluetooth/
And yes, I understand that Armbian is still being developed and not in anyway be perfect yet.
But still, I really appreciate everyone's work to make this incredible OS for SBCs.
Once again, thank you for helping me out You really saved my life
