Hello Guy's. I'm new here and I need some help.

I was trying to use MySensors on my Raspberry Pi 2, but I can't start the serial gateway.

Configurations:
No capacitor connected to the NRF24L01
not overclocked PI
CN not connected

I followed this tutorial:
http://forum.mysensors.org/topic/1151/tutorial-raspberry-pi-nrf24l01-direct-connection

When I start the program in get this output:

./PiGatewaySerial
Starting PiGatewaySerial...
Protocol version - 1.4
Created PTY '/dev/pts/1'
Gateway tty: /dev/ttyMySensorsGateway

and my raspberry freezes. I can't finish the processes with STRG+C. What do I need to do?

regards,
Ricardo Leoni
