When connecting the nrf module to a tiny85, connect MISO(pin7) on the module to MOSI/DI(PB0), and not MISO/DI(PB1). Here's the connections required:
nrf module ATtiny85 pin
SCK(5) PB2 (physical pin 7)
MOSI(6) PB1 (physical pin 6)
MISO(7) PB0 (physical pin 5)
Will I need to be using all of these pins listed above if i wish to only receive data from a transmission source? Thanks for the help, I do not have the Attiny with me yet but i have been able to walk through the setup a bit.
