As mentioned before i started with simplest possible 5-pin connection between attiny85 and nrf24L01 and moving forward.
Today I have 4-pin configuration working, with nrf's CE pin connected to Vcc. What is more important, now when i have pin 3 of attiny85 for my disposal, i started Serial output there. So now transmission and Serial working at the same time and i'm able to debug anything!
I'm using SoftwareSerial library and often you'll see it is not working with other libs since tiny85 only have 2 timers and limited interrupts, but this time it works perfectly and i'm surprized to get away with it this easy.
On the background is my "reciever" that i've assembled yesterday. It helps me quickly check if transmission is working (oled is black otherwise). And treminal is connected to tiny85 now.
