NRF24L01 Attiny bidirectional communication

Hi, i want to know if is possible to have a bidirectional communication with NRF24L01 working on Attiny85/84. I have seen examples of one Attiny only sending data, and bidirectional communication but only between arduinos uno using Ack payload. Is this possible with an Attiny, use ack payload?

If the Attiny85/84 can send and receive anything with an nRF24 then it can use all the nRF24 features. I have only used the nRF24 with an Attiny 1634.

This Simple nRF24L01+ Tutorial may help.
