MySensors Raspberry port suggestions

[mfalkvidd]

@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:

Makefile:17: Makefile.inc: No such file or directory

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.

[marceloaqno]

@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.

[ikkeT]

@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.

[marceloaqno]

@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 update your files from mysensors repository, this was fixed in #594

[ericvdb]

@marceloaqno said:

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

// Flash leds on rx/tx/err
//#define MY_DEFAULT_ERR_LED_PIN 12 // Error LED pin
//#define MY_DEFAULT_RX_LED_PIN 16 // Receive LED pin
//#define MY_DEFAULT_TX_LED_PIN 18 // Transmit LED pin

What do I put there? RPi pin numbers or GPIO numbers?

[marceloaqno]

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

[marceloaqno]

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.
