👑 DESCRIPTION 👑

This function takes a Bluetooth error code as input and converts it to an equivalent Unix/standard errno value. no cap, that's literally her whole job 💅

If the bt error code is known, an equivalent Unix errno value is returned. slay ✅

If the given bt error code is not known, ENOSYS is returned. so if she doesn't recognize the code, you get ENOSYS and that's the answer, periodt 💀
