Bluetooth: unable to connect to smartphone (Protocol not available)

I have an Intel 8265 card with integrated bluetooth. I just switched from Gentoo to Arch, and while on Gentoo I was able to connect to my smartphone (OnePlus 5T) and to receive files from it (but not send anything), on Archlinux I am unable to connect to the smartphone. From the smartphone, I am still able to send files to the laptop, however I am not able to send them from the laptop to the smartphone.
This is the output in dmesg:

This is what happens if I try to connect using bluetoothctl:

If I try to connect to the smartphone via blueman, it sometimes connects for less than a second and then it fails showing the following message: Connection Failed:  Protocol not available.
Any idea about what is going on here?
