Full duplex communication with NRF24L01

Hello, I'm Korean student, and i'm trying to make my own drone.

But I had a problem with communication.

I thought NRF24L01 was full duplex communication, but it was half duplex communication.

So I'm trying to make full duplex communication with two NRF24L01, because I want stable connection.

In theory, NRF24L01 uses SPI so if I connect two NRF24L01 to Arduino and give HIGH to both slave, and

with one slave, use MOSI and the other use MISO, they would be possible to communicate at same time.

Is is possible?

In short:

  1. Is stable connection possible with half duplex communication?

  2. Is full duplex communication possible with two NRF24L01?

ps. please forgive my poor English

There are no connections in a NRF24L01 system,
but a constant stream of packets could simulate something like it.

The communication between two node is halfduplex, but offers a back channel of the same width.
The switching between send and receive is done in hardware on both sides of the communication in synch.
