There should be a pull up on the MISO pin in the device specific radiopinfunctions.c

set_bit(PORT, PIN_MISO); // MISO pull up

Was not able to communicate over SPI without it.

Hi,

I'm using the library without any internal / external pull-ups for a long time.

Maybe your microcontroller - radio connection lines are long and you are needing a pull-up ...

Best,
ihsan.

I used a Arduino Nano. The signal looks fine on the oscilloscope but it should get a predefined state via pull up.
Maybe this will help somebody for future reference.
Thanks for your work! It is an awesome base for Arduino and ARM projects!
Cheers,
Martin
