Raspberry Pi 2 Serial Gateway [Solved]
-
Hi.
I have the Raspberry Pi Serial Gateway up and running on my Raspberry Pi Model B Revision 1.0. I can see incoming messaged when I do cat /dev/ttyMySensorsGateway.
I am trying to switch to my Raspberry Pi 2, but I am unable to compile Raspberry/librf24-bcm. When running make, the following error is shown:

That enabled the compilation to go through, but the gateway does not work. (Maybe because the IOBASE is wrong, or because I don't have the right modules loaded?)
/etc/init.d/PiGatewaySerial startstarts the gateway. No error messages are shown on the terminal.

Solved the problem. I installed http://tmrh20.github.io/RF24Installer/RPi/install.sh instead of the librf24-bcm library included in Raspberry. Re-compiled the serial gateway and installed it and it works perfectly now.

There is an issue on this.
mysensors/Raspberry#16
Maybe someone could create a PR with a working radio driver.

I had to switch back to librf24-bcm, see this thread. Not sure why, but I got no errors when compiling.
