💬 Building a Raspberry Pi Gateway

[gohan]

Exactly, I was about to write pretty much the same 😀

[Grubstake]

@gohan I beat you to it! :smiley:

[ccy]

@Grubstake: Thanks. I have tried to follow "NRF24L01+ Radio" pin out connection. I have double / triple check my wiring is correct. But I still get the same fail message in mysgw debug mode:

[root@alarmpi bin]# ./mysgw -d

Here is my /boot/config.txt:

initramfs initramfs-linux.img followkernel
dtparam=spi=on

and the spi dev:

# ls /dev/spidev0.*
/dev/spidev0.0  /dev/spidev0.1

I am using ArchLinuxARM:

# uname -a
Linux alarmpi 4.9.13-3-ARCH #1 SMP Fri Mar 3 18:45:16 MST 2017 armv7l GNU/Linux

I only wiring 7 pins (1-7) on NRF24l01+.

Output from MySensors configure:

# ./configure

I finally find out my raspberry pi board isn't detected properly in configure. I change the function detect_machine:

function detect_machine {
...
    case $hardware in
...
    BCM2835)
        soc="BCM2835"
        if [[ $machine == "Raspberry"* ]]; then
            local rev=($(detect_rpi_revision))
            if [[ $rev == "a02082" || $rev == "a22082" ]]; then
                tp="RPi3"
            else
                tp="Rpi2"
            fi
        fi
        ;;
...

make mysgw again, and I get this finally:

# ./mysgw -d

I can run mysgw. But what can I use it for? I want to make it control my light with 2.4G RF. But I don't know what to do next. Please advice Thank you.

[gohan]

@ccy
You need to provide some more details about your hw and general setup, what have you done so far, log messages, etc.

[ccy]

@gohan Sorry for my typo mistake. I can now run mysgw. But what can I use it for? I am trying to control my light with 2.4G RF.

[gohan]

Do you mean your light has already 2.4G RF or do you need to make a relay node with NRF24 that can switch on and of that light? But this is going a little OT in this thread.

[ccy]

@gohan Yes. I want to do that. I am sure my LED controller is 2.4G RF. But I can't detect any signal yet from my nrf24l01+ on raspberry pi. I am not sure what's wrong. Still trying now...

[gohan]

@ccy
Being 2.4G RF doesn't mean it is NRF24L01 compatible also without knowing what channel is using will make it even more difficult. So, unless you want to make a Mysensors LED Controller, I think you are out of luck if you want to directly control your existing one with a RPI and the mysensors gateway. Either way this is OT.

[ccy]

@gohan Is there a way to know the channel by doing some sort of scan? If the channel is known, what are the setting to fix the channel for mysgw?

[Velo17]

Hello everyone!

I'm using a Rasp2 (with the 40 pins GPIO header)

Has anyone experience with using the NRF module on different pins than default? I'm asking because I wonder if I can connect a GPIO-connected touch TFT (which would use the 2 CE lines for the touch and display interfaces) together with the NRF - by hooking the MISO/MOSI/SCLK to the default pins (and thus sharing them between the TFT and NRF) and defining free pins for the CE and CS lines in the ./configure script when compiling the gateway code...?!

Or maybe using the SPI1 by first enabling it as laid out in this blog post - but how to proceed from there? (How to tell the gateway code to use SPI1?)

[marceloaqno]

@Velo17

./configure --spi-driver=SPIDEV --spi-spidev-device=/dev/spidev1.0

(replace the /dev/spidev1.0 with the one you enabled in /boot/config.txt)

[engy]

Hello Masters,

Could you please help me with setting up virtual serial port?

I can't see the interface created under /dev.
I'm using the instructions and finish with the setup with the following command:

pi@raspberrypi:/tmp/MySensors $ ./configure --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyMySensorsGateway
[SECTION] Detecting target machine.
  [OK] machine detected: SoC=BCM2836, Type=Rpi2, CPU=armv7l.
[SECTION] Detecting SPI driver.
  [OK] SPI driver detected:BCM.
[SECTION] Detecting init system.
  [OK] init system detected: systemd.
[SECTION] Saving configuration.
[SECTION] Cleaning previous builds.
[OK] Finished.

pi@raspberrypi:/ $ sudo /usr/local/bin/mysgw -d
mysgw: Starting gateway...
mysgw: Protocol version - 2.1.1
mysgw: MCO:BGN:INIT GW,CP=RNNG---,VER=2.1.1
mysgw: TSF:LRT:OK
mysgw: TSM:INIT
mysgw: TSF:WUR:MS=0
mysgw: TSM:INIT:TSP OK
mysgw: TSM:INIT:GW MODE
mysgw: TSM:READY:ID=0,PAR=0,DIS=0
mysgw: MCO:REG:NOT NEEDED
mysgw: Listening for connections on 0.0.0.0:5003
mysgw: MCO:BGN:STP
mysgw: MCO:BGN:INIT OK,TSP=1

Everything seems to be OK. However, when I check /dev directory, the interface is not created.

What could be an issue?
Thank you in advacne!

[gohan]

Why don't you compile it as ethernet gateway?

[engy]

@gohan Etherner Gareway is not supported by OpenHab MySensors binding.

[gohan]

Mqtt? 😀

[engy]

@gohan I'm sorry, MQTT is not supported by OpenHab MySensors binding. Ethernet Gateway is not supported on Raspberry PI.

[marceloaqno]

@engy OpenHab2 supports mysensors serial and ethernet gateways:
https://github.com/tobof/openhab2-addons/wiki

Maybe the build guide may have given you that impression, but ethernet Gateway is supported on Raspberry PI:

./configure --my-gateway=ethernet

[keldandorin]

@gohan Solved the problem with radio...Thx

[engy]

Thank you guys for prompt reaction. Indeed, Ethernet GW works flawlessly!
