@TriXwooD said in Double SPI Radio Raspberry Pi: dtparam=spi=on dtoverlay=spi1-1cs,cs0_pin=36 @TriXwooD : Thank you, this helped me a lot. I had to use a different pin number in /boot/cmdline.txt though for that it matches the pin number given in the configure statement: dtparam=spi=on dtoverlay=spi1-1cs,cs0_pin=16 ./configure --my-rf24-cs-pin=36 ... Configure wants the BCM pin number (36), but the dtoverlay wants the corresponding GPIO pin number (16).

Yes I got that from the examples. But my question is: on the gateway itself, which has to do something to talk to the other nodes (?). If I add a sensor to the gateway itself, then what do I do? Can I use sleep()? will the gateway function properly? Ok I tried wait(), for some reason wait() did not worked before, (got only one message) now it works...
