Invalid [Mi PAD 4] bluetooth

[johnatanrochars]

I can not add my watch as a trusted device to unlock my phone.
The menu of trusted devices appears, the right one appears; but in the advanced screen unlock settings, when adding a device, neither my connected phone appears, nothing appears.

And I can not plug my adapter pendrive into the tablet, it does not light up the pendrive's working light.
use rom EU 10.3.2 estable

The secure unlock option only works with some xiaomi Bluetooth devices like the MI band. I don't know if that's your problem.

As enigmedark said, unlocking using Bluetooth is only supported with Mi devices.
