(solved)
Hi. Thanks a lot for this implentation and the helpful posts here!
I've got the gateway working with a tmp75 temperature sensor on an arduino. The nrf24 is sitting on the raspberry directly (CE pin 22), as a controller i'm using PiMatic. It works very nicely!
There is one small problem however. The PiGatewaySerial will only work if i have called PiGateway before (and closed it again). With working I mean picking up radio transmissions from my sensor node. Everything else seems normal (/dev/ttyPiGatewaySerial and radio details printout).
The details of both configurations might give a clue:
pi@raspberrypi ~/mysensors_rpi $ sudo ./PiGateway

after closing PiGateway and opening PiGatewaySerial i get this:

Notice how the CE pins of both SPI configurations are different!
I'm at the point that i want to daemonize the gateway. Which in fact i did, but the same problem persists. Before i hack the startup script to first run and close PiGateway before PiGatewaySerial, i was hoping that someone has an idea what i'm doing wrong.
Thanks in advance!
solved!
I have two RPIs (a Pi 2 B and a Pi B+), which both worked with the pyRF24 lib of TMRh20, so when i had a look in the source of the radio initialization of PiGatewaySerial and found this:
#ifdef __PI_BPLUS
gw = new MyGateway(RPI_BPLUS_GPIO_J8_15, RPI_BPLUS_GPIO_J8_24, BCM2835_SPI_SPEED_8MHZ, 1);
#else
gw = new MyGateway(RPI_V2_GPIO_P1_22, BCM2835_SPI_CS0, BCM2835_SPI_SPEED_8MHZ, 1);
#endif
When i changed it to:
#ifdef __PI_BPLUS
gw = new MyGateway(RPI_V2_GPIO_P1_22, BCM2835_SPI_CS0, BCM2835_SPI_SPEED_8MHZ, 1);
#else
gw = new MyGateway(RPI_V2_GPIO_P1_22, BCM2835_SPI_CS0, BCM2835_SPI_SPEED_8MHZ, 1);
#endif
and recompiled the gateways,it all started to work. After powerup everything runs :).
The Rpi that is connected now is the Pi 2 B. So i guess either i have my nrf25 wired differently then defined in this lib, or the precompiler was thinking i have a B+ connected. Or both.
I will find out when i get this also working on my B+.
