💬 Building a Raspberry Pi Gateway

@gdekeijzer There was a recent update on the random number generator for the RPi port, but unfortunately not all linux versions support the new method. @d00616 is working on a solution to this problem #856. Please use the master branch for the time being.

[gdekeijzer]

Ah great. Thanx for the response. I'll go try that for now.

[gdekeijzer]

Installed master branche. That did the job. Thanx.

Hello, did anyone tried gateway on pi with RS485 wired network ? It looks like node with ID set is looking for parrent and gateway does not respond to the node and therefore there is no succesfull presentation.
example from GW mysgw:

@Luc3as Okay, Again I found answer while after asking, I used dev branch of mysensors and it is working like a charm.

I am a novice, trying to get the raspberry pi gateway to work. I did get it to work on one pi, but while installing it on the second, it produces the following error:

In file included from examples_linux/mysgw.cpp:74:0:
./MySensors.h:254:2: error: #error No support for nRF24 radio on this platform
#error No support for nRF24 radio on this platform
^
In file included from ./drivers/RF24/RF24.cpp:23:0,

from examples_linux/mysgw.cpp:74:
./drivers/RF24/RF24.h:52:17: fatal error: SPI.h: No such file or directory
#include <SPI.h>

I can see that the SPI.h library is among the files downloaded.

Any ideas?

Paul

[gohan]

what raspberry version is that? What library version did you download?

[Luc3as]

do you have SPI enabled through raspi-config ?

[zavracky]

@gohan Thanks for the response. I downloaded the MySensors Library 2.1.1. Sorting through it I can see that SPI.h is included.

I installed a complete system in FL (I'm retired and a snowbird). Included are a Bunch of Arduino sensors, a Foscam Camera and Wemo switches. So I used a lot of material from MySensors to get the Arduino sensors up and running (great stuff: thanks to all those folks who created it). I then created a Raspberry Wireless (RF24) Gateway and installed Mosquitto to communicate with HomeAssistant. Took a while to configure HA, and I'm still learning.

I do not recall having a problem with the SPI library when assembling all this stuff. Upon return to Boston, I have made a number of improvements talking to the Raspberry in FL through TeamViewer (a great app). However, along the way, I corrupted the system in FL. It now limps. So, I started recreating the stuff in FL on a new SD card, encountering the SPI problem.

Since sending out my request for help, I found a backup version of my FL system on an SD card. Looking at it, the system seems to be whole and boots with no issues. mysgw works fine on it. So, I've added all my new stuff to this SD card and have tested it to make sure its working. Things are looking good and so, my immediate problem is solved (circumvented).

I still want to know what I am doing wrong with the gateway. I've learned a little bit of Python along the way. There, one installs a library. I know effectively nothing about C++. So, I've done nothing to install the library, only followed the instructions on the MySensors Raspberry Pi Gateway page.

BTW, this stuff is great.

Paul

[zavracky]

@Luc3as Thanks for your response. No, in fact it was not enabled. Please read my reply to gohan. As you see, I've cheated my way out of this problem. In the process, I've lost track of the SD card on which I encountered this problem. Nonetheless, I will circle back to test your suggestion.

[gohan]

Try to enable the SPI first. Then you could also try different linux distributions and see which one you like better ( I personally like dietpi more than the others ). You may also want to try to use Mysensors library from development branch that is now 2.2.0.
I now have a dietpi + mysensors 2.2.0 + nrf24 and all running fine

@marceloaqno said in 💬 Building a Raspberry Pi Gateway:

@Roberto-Mo-Ca If you are using the nrf24 PA/LNA version you need to use a 5V->3.3V regulator otherwise you can connect to the 3.3v pin.

But why do we need to convert down from 5v to 3.3v? The pi does supply 3.3 on some pins.. Is this because the PA/LNA uses more mA?

[gohan]

yes, the 3.3v can't supply enough current. I am using some small adapters that have the AMS1117 and some capacitors that allow for a quick swap of radio modules when you need test them

Ok. Maybe this should be mentioned in the documentation page.

[mfalkvidd]

@subutux could you explain where you would expect to find that note?

[mfalkvidd]

(obviously not here)

[gohan]

@subutux it is mentioned as stated above that you need it, it is just skipping all the info that are in datasheets and are not stricly necessary to make the gateway

Well, I for one would like to know why we need to step-down from 5v to 3.3v. Just a simple statement that the LNA version requires more power that only the 5v can deliver on the pi.
@mfalkvidd Yeah I would mention it there. It mentions to use a regulator but not why.. I've read that line & was like, why? That's when I've started a search in the forums here.

[mfalkvidd]

@subutux I've updated the text. Do you think it is ok?

yup! thanks!
