Nano to Attiny85 conversion and the nRF24L01 module

Other Hardware Product Design
1

Hi, i'm working on a wireless project that will ultimately use 5 Attiny85's and 5 nRF24L01's to send a signal one Arduino Nano and nRF24L01 which will control relays based off the signals from the 5 transmitters.

I have a little test setup using two Nano's and the "GettingStarted.ino" example. Everything works great. I switch the transmitter over to a Attiny85 and everything stops. I am using the example code, rf24ping85.ino. I've triple checked the wiring that the wiring matched the diagram in the program. Because the Attiny85 doesn't have a serial output I am struggling to debug the program and/or wiring.

The programs are attached below.

Any suggestions based off the code and setup?

Thanks
