Dual role

Hi,

As i understand it it's possible to switch role between central and peripheral to scan or advertise, but you can't do both at the same time.

Then I wonder if it's possible in the peripheral role to accept a connection and then switch to central mode and start scanning while keeping the connection from the periperal role alive?

And also the other way around, while in central mode connect to a peripheral device and then switch to periperal role and start advertising while keeping the connection from the central role alive?
