💬 Building a Raspberry Pi Gateway

[mfalkvidd]

@pete1450 could you clarify which instructions should be updated?

The instructions at https://www.mysensors.org/about/arduino recommend using the Arduino IDE Board manager, which will get the latest stable version.

Edit: Now I see. The link in the first post in this thread. It doesn't mention the master branch because up until Dec 25th the development branch was required. But now that 2.1 has been released the instructions should indeed use the stable version. I've updated the instructions. Thanks for noticing!

This is also new for me since i do not send data into any cloud... but i can imagine that you can use MQTT. (see https://www.mysensors.org/build/mqtt_gateway for more details) is important that the receiving side supports MQTT. in this case google is your friend ;)

if you do a ./configure --help you will find you can build the mysensors gateway with MQTT support

./configure --help 
...
    --my-gateway=[ethernet|serial|mqtt]
                                Gateway type, set to none to disable gateway feature. [ethernet]
    --my-node-id=<ID>           Disable gateway feature and run as a node with given id.
    --my-controller-url-address=<URL>
                                Controller or MQTT broker url.
    --my-controller-ip-address=<IP>
                                Controller or MQTT broker ip.
    --my-port=<PORT>            The port to keep open on gateway mode.
                                If gateway is set to mqtt, it sets the broker port.

ran sudo ./bin/mysgw -d
I keep getting mysgw: accept: Bad File Descriptor.
Any possible cause ?

[marceltrapman]

I am trying to get the raspi ethernet gateway running but on both my pi 3 (also running openHAB) and the pi B (pretty basic install).

Unfortunately I get the same error on both.

Any ideas what could be going on here?

I am running the latest gateway and the latest raspbian.

mysgw: Starting gateway...
mysgw: Protocol version - 2.1.0
mysgw: MCO:BGN:INIT GW,CP=RNNG---,VER=2.1.0
mysgw: TSF:LRT:OK

@marceltrapman

I am using a Rasp Pi 3 as well.
I can't even proceed further in the tutorial cause of this error cause nothing works after it.

@marceltrapman @LaMB95
Could you post the complete ./configure command used to configure the gateway?

[marceltrapman]

@marceloaqno Sure, forgot it :)

sudo ./configure \
    --my-gateway=ethernet \
    --my-controller-ip-address=192.168.1.xx \
    --my-port=5003 \
    --my-transport=nrf24

[marceloaqno]

@marceltrapman Are you sure it's not a problem with your controller?
Have you tried connecting to your controller using telnet?

telnet 192.168.1.x 5003

[LaMB95]

@marceloaqno !

Is this what you meant?

[marceltrapman]

@marceloaqno not sure no.

So, I downloaded telnet on the same raspi that I want to use as the gateway and the issue seems to be that port 5003 is not available.

Funny but how do I solve this.
It can't be an issue with the firewall because it allows all traffic on the internal network.

[marceltrapman]

@marceloaqno and the same from the controller to the gateway gives the same error on that port :(

[marceloaqno]

@Reza Yes, you can use rs485 in the RPi.

./configure --my-transport=rs485 --my-rs485-serial-port=<YOUR_SERIAL_PORT>

For more options, run:

./configure -h

[marceloaqno]

@LaMB95 No, I meant the options you used when you ran ./configure

@tiana
"The Broadcom SoC has three independant SPI interfaces, however only one of these is brought out to the GPIO connector, and that one SPI interface has 2 Chip enable lines."

[marceltrapman]

@marceloaqno from the docs I assume it is the gateway that has to open up port 5003 but I guess it does not because it can't connect to the ethernet (for some reason) or am I wrong?

[Reza]

@marceloaqno
i means that without arduino and usb port, similar to raspberry gateway ( raspberry +nrf24)
i means connect rs485 module to GPIO raspberry pi :) with domoticz

[LaMB95]

@marceloaqno

I m sorry I m new to using a raspberry pi and its for a project.
But if this is not what you asked for could you be a little more specific :$

[ericvdb]

use sudo ;)

[marceltrapman]

Oh and one other thing, when I set the gateway up for MQTT it works.

[marceloaqno]

@marceltrapman

If you use the --my-controller-ip-address= option, the gateway will act as a client and attempt to conect to the supplied ip and port. If you want the gateway to open port 5003, omit this option.
