💬 Building a Raspberry Pi Gateway

@sineverba said in 💬 Building a Raspberry Pi Gateway:

Hi to all,
I'm testing an ethernet gateway on RPI3, with nrf24 + 1 node with a relay.

I want introduce security and signing. On Arduino gateway / node no problem at all, but, how to do on the RPI3 as gateway?

I would get / create / set a software serial on PI itself and whitelisting it on the node, after I will introduce the AES Key and signing.

Cannot find in documentation how do it on PI3. Thank you very much!

@mfalkvidd I'm trying today, but to compile correctly the Docker image I'll have to clone to my github account :( or at least locally. My Dockerfile for the "Alpine edition" for Hass.io is simply:

ARG BUILD_FROM
ARG BUILD_ARCH
ARG BUILD_DATE
ARG BUILD_REF
ARG BUILD_VERSION

FROM ${BUILD_FROM}

ENV CONFIG_PATH=/data/options.json
ENV APPDIR=/opt/MySensors

RUN apt-get update && apt-get install -y --force-yes \
    make \
	 g++ \
	 git \
	 && rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/* ~/.cache \
	 && git clone https://github.com/mysensors/MySensors.git --branch development $APPDIR


# Copy root filesystem
COPY rootfs /

#CMD [ "/run.sh" ]

I deleted the LABELS 'cause... the data is still too rawly "buried" from others. :tongue:

The Configure and Make is in run.sh.

BTW, I still need to figure out how to start mysgw as service... Mainlyt I'd like to redirect the log: how can I do this safely?

And... can I use the rx/tx/err led feature on Raspi too (aside being in a Docker) ?

EDIT: the code add works!
Another question: I'm not getting far from this... what is it trying to do?

@ghiglie Thank you, I did see that was for 2.1.1. Just playing with them!

Does the Pi Gateway support the MY_SIGNING_SIMPLE_PASSWD option? I couldn't find anything about that. I've been gearing up to use that feature in my network, but I've also been playing with moving my gateway onto my Pi Zero W.

[gohan]

@alowhum If you want to just encrypt data, just add the encryption key in the myconfig.h file and compile it

[MasMat]

@gohan N00b question, but which steps from the step-by-step need to be redone to "compile it" after altering myconfig.h? Or can you just post the command lines? :flushed:

[gohan]

As soon as you do the changes in myconfig.h before the MAKE, you are fine

[sentur]

Anyone tried using the new Pi Zero WH as a Raspberry Pi Gateway. Presumably by MQTT and using NRF24 radio?

@alowhum Have you been able to setup a gateway with your Raspberry Pi Zero?

[MasMat]

@sentur That's what I'm doing now. Except mine is Zero W. Soldered the pins on myself.

[marceloaqno]

@alowhum yes, to use MY_SIGNING_SIMPLE_PASSWD feature, add the following to your list of configure options:

... --my-signing=password --my-signing-password=<PASSWORD>

[Richard van der Plas]

Is there anyway where i can see if i have IRQ configured ?
ive build it a long time ago, but now upgraded to a nrf24 PA/LNA and have more an more sensors.

[gohan]

look inside makefile.inc in mysensors folder, that should contain the parameters you set in ./configure

[Richard van der Plas]

@gohanm, as it seems not ?, can i rebuild it easily? ```

SOC=BCM2837
CPPFLAGS=-march=armv8-a+crc -mtune=cortex-a53 -mfpu=neon-fp-armv8 -mfloat-abi=hard -DMY_RADIO_NRF24 -DMY_GATEWAY_LINUX -DMY_DEBUG -DLINUX_SPI_BCM -DLINUX_ARCH_RASPBERRYPI -DMY_PORT=5003
LDFLAGS=-pthread
PREFIX=/usr/local
CC=gcc
CXX=g++
BUILDDIR=build
BINDIR=bin
GATEWAY_DIR=/usr/local/bin
INIT_SYSTEM=systemd
SPI_DRIVER=BCM```

[gohan]

make a copy of it and make a ./configure with the IRQ enabled and see what you get

[Richard van der Plas]

@gohan make a copy of the makefile.inc and restart the ./configure command again you mean ?
ill try it tomorrow, too afraid to break things late in the evening ;)

[gohan]

as far as you don't execute the MAKE command you are ok. Also make a copy of the mysgw executable just as backup if you never did it

[Richard van der Plas]

but ill have to do it sometime , just ./configure with all the options, build , test and install ?

[gohan]

if you only want to check if irq is enabled, otherwise you could just build it fresh with irq enabled and you can go back by replacing the mysgw executable

[Richard van der Plas]

@gohan ty
