nRF51X22: BLE and Beacon at the same time?

[lnBetween]

Can the nRF51X22 be paired with an iPhone to communicate (both ways) using regular BLE and emit a beacon signal at the same time? In fact, I'm looking to change the beacon Major/Minor values on the fly using the synced BLE connection with the iPhone. Is this doable?
