Bluetooth Issue with usb Dongle

[modernkoala96]

Hello I have a small problem, I bought a Macbook Pro 13 2016 which has a defective Bluetooth. I ordered a bluetooth dongle and it works. Unfortunately I can't really get it to run on Mac OS. I installed the Brcm patch and now it also activates Bluetooth after the restart. But if I turn it off, it won't turn back on. It finds devices but I can't connect to them. Handoff and airdrop don't work either. I am afraid that it is related to the defective internal hardware, but how can I design it from the software
