MySensors Raspberry port suggestions

Update: Added support for status leds (RX/TX/ERR), you can enable it in examples_linux/mysGateway.cpp file.

Continuing the learning here, new questions... Thanks so far, I've now got the temp/hum/door messages sent and received from sensebender micro to raspi2. The next thing I would like to do is to send the messages as mqtt to the next box hosting some controller.

How to get the mysGateway to send the stuff forward as mqtt? I tried to look into Makefile, MyConfig.h and such, but didn't quite figure out yet how to do that. Any pointers?

So I'd like to have the following: sensebender -> radio -> raspi2 -> some box hosting the controller. Perhaps even outside of home, so routable traffic e.g. to OpenShift.com.

Should I now somehow configure and build mysGateway to send stuff as MQTT, or pipe the traffic somehow to mqtt like mosqitto? How is this normally done if the controller server is not running on the gateway Raspi?

Thanks for the patience, I'm just getting into all this interesting stuff :)

@ikkeT I haven't tried but using nodered should be fairly simple and very flexible. This discussion might be useful: https://forum.mysensors.org/topic/2802/flow-to-turn-serialgateway-into-mqtt-serialgateway/

hawk_2050

@ikkeT you can build the Raspberry Pi mysGateway as either Serial, Ethernet or MQTT by using appropriate commandline parameters with the configure script. Just do ./configure --help and you'll get a list of all the options available. Once you've chosen your options and run configure then you 'make'. An example of a set of options that will generate an MQTT Gateway is:
./configure --my-debug=enable --my-gateway=mqtt --my-rf24-channel=100 --my-rf24-pa-level=RF24_PA_LOW --my-controller-ip-address=127,0,0,1 --my-port=1883
--my-mqtt-client-id=MyGW2 --my-mqtt-publish-topic-prefix="MyGW2out" --my-mqtt-subscribe-topic-prefix="MyGW2in"

In this case my MQTT Broker is Mosquitto and is on the same Raspberry Pi hence the use of 127,0,0,1 for the specified --my-controller-ip-address. Change that as appropriate to your intended setup.

Hope that helps.

@marceloaqno I have been trying to build this out by first building the RF24 library using the following:

git clone https://github.com/TMRh20/RF24.git
cd RF24
make
sudo make install

However, this fails on the make command:

cc1plus: error: bad value (cortex-a7) for -mtune switch
Makefile:40: recipe for target 'RF24.o' failed

I am not sure what to do here. Looks like the gcc does not support the cortex-a7? I am trying to run this on my RPi 2 B.

@wergeld I'm not sure why you are having this error, perhaps your version of gcc it's old? Did you try to update it?
You can skip the installation of TMRh20/RF24, it is no longer necessary to build RPi port.

I have tried to update gcc but apt-get says it is already at latest version. I am upgrading to Jessie now as it has gcc 4.9 (I was running Wheezy with gcc 4.6).
Is there an updated build instruction set? I am planning on using this as a serial gateway with Domoticz on same RPi.

@hawk_2050 thanks for the reminder! I recalled it was somehow configurable, but I forgot it was through . /configure options. I'll try after getting pir working also.

@wergeld I updated the building instructions:

Success! Upgraded to Jessie and build worked fine. Now to reconnect my radio to the RPi pins directly to test.

Okay, using an RPi2B upgraded to Jessie from Wheezy I have successfully built and set the mysGateway as a daemon. My configuration was:

./configure --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyUSBMySensorsGateway --my-rf24-pa-level=RF24_PA_LOW

This was immediately available in Domoticz under Hardware. I re-added the 2 nodes and away I went!

Full command list:

git clone https://github.com/marceloaqno/MySensors.git
cd MySensors
./configure --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyUSBMySensorsGateway --my-rf24-pa-level=RF24_PA_LOW
make
sudo make install
sudo mysGateway -b

In Domoticz it lists this gateway as running:
MySensors Gateway USB
Version: 2.0.1-beta

So far very happy with this setup. No wires and no extra arduino needed for serial gateway. Just the NRF+RPi interfacing via:

@ericvdb In any type of pin configuration for the RPi, always use the physical pin number.

The RPi port was merged into mysensors official repository :tada: (thank you to everyone who helped with this process :clap: ). For future discussion, please use this this topic.
