💬 Building a Raspberry Pi Gateway

TommiP

Hi
Is anyone else having this same problem on Rpi3?: Gateway works ok after "sudo make install" with openHAB. With "sudo ./bin/mysgw -d" I can get debug log visible and log works ok.
But if I run "sudo systemctl enable mysgw.service" after "sudo make install", debug log start showing endlessly "mysgw: accept: Bad file descriptor". So debug log function gets destroyed and it can't be used anymore. I have made several clean installations and every time this same happens.

@TommiP What I think is happening is that you are running two instances of the gateway.
If you need to get the debug logs, first stop the mysgw service:

sudo systemctl stop mysgw.service

@marceloaqno
Ok, now I understand what happened, thanks.

Re: 💬 Building a Raspberry Pi Gateway

Silly questions, I'm a little bit confuse.
I have a serial Gateway running with arduino nano + nrf24 and a raspberry pi with domoticz on board. The link between domoticz & Gateway is done via USB <=> serial port (/dev/ttyUSB0). This setup runs like a charm.

Now, I would like to access to my Gateway via the network because I would like to use "Over The Air " functionnality with MYSController.

Can I install MySensors Gateway on the raspberry and keep the arduino + nrf24 connected via usb ?? For the moment, I can not use GPIO port.

If for some reason you can't use the GPIO pins of the Raspberry Pi, you could connect the radio to a arduino with the GatewaySerial sketch and feed the pi through a serial port:

./configure --my-gateway=serial --my-serial-port=/dev/ttyUSB0 --my-serial-baudrate=115200

Where is my mistake ??
Again, Can I install MySensors Gateway on the raspberry and keep the arduino + nrf24 connected via usb or I must connected the nrf24 directly with GPIO on the Rasp ??

Thanks in advance for your reply.

@romeo01 I think that connecting nrf24 directly to arduino and compile mysgw as ethernet gateway is the cleanest solution (I have it as MQTT and it is working fine, but ethernet is the same). Keep in mind that you'd better use one of those adapters 5v-3.3v for nrf24 chips + capacitor because the 3v output of raspberry isn't very suited for the task.

romeo01

Thanks gohan for fast answer.

Arduino nano + nrf24 are already connected together. Hardware is already built.

How access to the gatway installed on the raspberry via the network and use my arduino + nrf24 connected via usb/serial to the raspberry ??

Sorry but I do not understand what you mean
...compile mysgw as ethernet gateway is the cleanest solution...

If I configure on this way
./configure --my-gateway=ethernet --my-port=5003

I could access to my Gateway via network an the Gateway will use the arduino + nrf24l via usb/serial ??

That's why I say I'm confuse.

--my-gateway=serial

What is this option ? The link between gateway and nrf24 or the way to access to the Gateway ??

romeo01

In summary,

Is the Gateway (software) installed on the raspberry, is able to manage the nrf24 connected on arduino via USB/Serial port ??

gohan

no, I don't think so. If you want to manage nodes over network you need to make an ethernet gateway (could be a UNO with w5100 shield, an esp8266 or mysgw compiled on raspberry)

romeo01

nrf24 connected to a arduino nano and plugged to the raspberry over the usb/serial cable is not considered as a serial device ?

What is this option ?

--my-gateway=serial

If for some reason you can't use the GPIO pins of the Raspberry Pi, you could connect the radio to a arduino with the GatewaySerial sketch and feed the pi through a serial port:

That's exactly what I need, but how to do ??

./configure --my-gateway=serial --my-serial-port=/dev/ttyUSB0 --my-serial-baudrate=115200

Serial port /dev/ttyUSB0 is ok, because I use this with domoticz and it'running good.

My initial question is how to use my old gatway (arduino + nrf24) with the gateway compiled on the raspberry over the usb/serial cable ?
I can not use GPIO port.

gohan

The serial gateway on the raspberry does what your nano is doing and you can't have gateways talking to each other. Maybe you could look at mycontroller and see if can manage nodes the way you want.

When talking about this Raspberry Pi Gateway, I suppose, that its just connecting the NFR24L01+ to the Raspberry Pi GPIO and run

./bin/mysgw -d

right? On my Pi it does not work this way, maybe the NFR24L01+ is not ok. Instead I am running an external esp-wifi-gateway, but a direct gateway seems the better solution to me.
So did I get it right, that I can use a NFR24L01+ connected to the Raspberry PI GPIO without any external gateway? If so, what are the parameters for building the mysgw daemon? I tried this one:

./configure --spi-driver=SPIDEV --spi-spidev-device=/dev/spidev0.0

update: as in https://www.mysensors.org/view/180#wiring
22 – CE
24 – CSN/CS
23 – SCK
19 – MOSI
21 – MISO

SPI is activated:

$ls /dev/spidev*
/dev/spidev0.0  /dev/spidev0.1

And this is the result, when building it with the settings mentioned above. (Raspberry Pi 3, jessie 4.9.13-v7+)

$ sudo ./bin/mysgw -d
mysgw: Starting gateway...
mysgw: Protocol version - 2.1.1
mysgw: MCO:BGN:INIT GW,CP=RNNG---,VER=2.1.1
mysgw: TSM:INIT
mysgw: TSF:WUR:MS=0
mysgw: !TSM:INIT:TSP FAIL
mysgw: TSM:FAIL:CNT=1
mysgw: TSM:FAIL:PDT
mysgw: TSM:FAIL:RE-INIT
mysgw: TSM:INIT
mysgw: !TSM:INIT:TSP FAIL
mysgw: TSM:FAIL:CNT=2
mysgw: TSM:FAIL:PDT
mysgw: TSM:FAIL:RE-INIT
mysgw: TSM:INIT
mysgw: !TSM:INIT:TSP FAIL
mysgw: TSM:FAIL:CNT=3
mysgw: TSM:FAIL:PDT
mysgw: TSM:FAIL:RE-INIT
mysgw: TSM:INIT
mysgw: !TSM:INIT:TSP FAIL
mysgw: TSM:FAIL:CNT=4
mysgw: TSM:FAIL:PDT

And can someone show how to bind this gateway into FHEM? As said, today I am running an esp-wifi-gateay.

Thanks in advance for any support...

@gohan
With the serial Gateway on the raspberry; how is connected the nfr24 ??
If usb/serial port is no possible, which serial port to use ?

keldandorin

@gohan Been trying to find my old post to tell you all how it got with my rpi and nodes that did not register. I bougt some voltage regulators LM350. used the 5v output insted of 3.3 V but still no luck to get node to register. when messauring volatage when GW send awnser it drops way below 3.3v. I think voltage output from rpi just is to bad. So I bought a nodemcu for GW instead and it works like a sharm :)

marceloaqno

@romeo01 You have to connect the nrf24 to the GPIO if you want to use it with the RPi, the information on the wiki was wrong, sorry about that.

gohan

@marceloaqno he said he can't connect nrf24 chip on the rpi, so that's why he is struggling

marceloaqno

@dirkc Try to connect your module to the SPI0 (https://www.mysensors.org/view/180#wiring).
You only need to enable the SPIDEV if you want to use the SPI1.

gohan

@dirkc I don't know where you got those pin numbers but they don't look like the ones on the guide. In addition you don't have to use spi driver. The PA version of nrf24 are quite a pain to get them working, so I suggest you first test with regular modules and then upgrade to PA

dirkc

@gohan, @marceloaqno : sorry, I corrected the "typo", the NRF was already connected as shown in https://www.mysensors.org/view/180#wiring. I double checked that again.
What is the correct setup for ./configure ?

romeo01

@marceloaqno

Thanks marceloagno, the answer is clear.

Keep up the great work !

marceloaqno

@dirkc The default settings for ./configure is to use the nrf24 module connected in the same way as shown in the guide and as an ethernet gateway.
