@foad62 I don't know if it helps but you can modify the default pins MySensors expects the NRF chip to be connected to. Here is an example, works on my Nano with MySensors 2.0:

#define MY_RADIO_NRF24
#define MY_SOFTSPI
#define MY_RF24_CE_PIN 11
#define MY_RF24_CS_PIN 6
#define MY_SOFT_SPI_SCK_PIN 10
#define MY_SOFT_SPI_MISO_PIN 9
#define MY_SOFT_SPI_MOSI_PIN 7

#include <SPI.h>
#include <MySensors.h>

In my case I didn't try connecting another SPI device, I just moved the pins for easier NRF soldering on a perfboard.
