Bluetooth can not recognize any device

I recently decided to be a full-stack Ubuntu user, abandoning everything connected to Windows (dual boot, etc.).
I only have one problem: my Bluetooth device can not find any device!
I am using 18.10, and whenever I want to connect my DualShock 4 controller or my phone, I can not connect or recognize them. I validated and they are recognizable, I also tried to use blueman to fix things, but it still does not work. Any ideas? My dongle is a bcm20702a0
