Bluetooth (Blueman) unable to find any devices and can't be found

Hello, I've been using arch for some years and always got lazy about setting up bluetooth, so I thought today would be a good day but I haven't been able to do so, I've been looking at a lot of threads in this forums and looking around the web and haven't been able to get it right.

I have bluez and blueman for the bluetooth, the bluetooth service is enabled and running

$ sudo systemctl status bluetooth.service

There seem to be three problems with it though, hciconfig and hcitools show something about it and it seems like blueman does recognize the existance of the bluetooth device, but I can't get it to find any devices (my phone) and my phone can't find the laptop either (I did make sure to toggle visibility)

$ hcitool dev

hciscan does not show anything, I do belong to the lp group (which the wiki says you need to be in)

$ hcitool scan

I use Fluxbox so no full desktop environment, I did make sure I add blueman-applet to autostart, the bluetooth works fine on windows, is enabled there, and I have no way to turn bluetooth off with a key nor a switch on the laptop, here are other things I think might be useful

$ rfkill list

I'm not sure what can be wrong, thanks in advance
