I purchased several Nrf24L01+ (RF24) Radios to use with my Arduino uno and Micro.

Using the GettingStarted sketch and Nrf24L01+ connected to my uno, I get nice debugging info in my serial monitor. However when I connect the Nrf24L01+ to my Micro, upload the sketch and open the serial monitor I get no debugging information. There is no info displayed in the serial monitor.

Also the arduino uno when set to Transmit, does not see the other Nrf24L01+. Any help would be appricated

Here is my pinout to connect the Nrf24L01+ to the micro:

Line    From Arduino Pin    To Nrf24L01+ 
GND     GND                 1
3V3     3V3                 2
CE      9                   3
CSN     10                  4
SCK     SCK                 5
MOSI    MOSI                6
MISO    MISO                7

Here the Nrf24L01+
