Raspberry Gateway + Arduino pro mini (atmega328p) NRF24L01 (without plus +)

@alop you'll have a hard time getting help from anyone until you have capacitors on the radios. Power issues are the top 1, 2, 3, 4 and 5 issues if you look at the problems people are having. Yes, sometimes it works with a very simple example. No that does not mean that your power is stable enough.

https://www.mysensors.org/build/raspberry#advanced shows how to set defines if you don't want to modify MyConfig.h, but modifying MyConfig.h also works. I prefer the -D variant because then I can easily switch MySensors versions in git without having to re-apply the changes.

[alop]

@mfalkvidd OK. I just bought some 4.7 capacitors :)
I'll make the setup with them.

Just to clerify, if I change MyConfig.h on raspberry it is not enough just to save the file and "build" the gateway with other parameters?
Maybe this is why I dont receive any signal.

[mfalkvidd]

@alop geat.
Until you have the capacitors in place, see if sundberg's advice on moving the nodes apart helps, about 2-3 meters. The signal can become too strong.

[alop]

@mfalkvidd
Just in general: What is the procedure if I change the MyConfig.h on raspberry?

[mfalkvidd]

@alop edit it with your favorite editor?

[alop]

@mfalkvidd Ok, so far :)
But do I need to "compile", "build", "make" something so that changes in MyConfig.h will be taken?

[mfalkvidd]

@alop ok :)

I think make is sufficient (and make install if you want the new binary installed).

make is smart enough to recompile everything that has been modified.

[alop]

@mfalkvidd
Unfortunatelly no change after adding capacitor :(
Now I have bought NRF24L01 WITH Plus and I'm trying with them.
I have reinstalled from skratch everything.
Gateway and sensor are now ca. 3-4 meters appart.

 * The MySensors Arduino library handles the wireless radio link and protocol

 * The sensors forms a self healing radio network with optional repeaters. Each

 * network topology allowing messages to be routed to nodes.

It's a workaroud, but not "nice".
Since I have no problem on creating gateway on another arduino pro mini, I just connected per USB the arduino to RP3 and everything is working fine.
So sensors can be read by a controller (home assistant).
Big downside is, that for pro mini I have to use usb to ttl convertor in between.
Maybe the code for raspberry is with bugs, since to be able to see my rf radio on raspberry I had to install the "development" branch.

[gohan]

the development branch works well, why don't you use it on the RPI?

[alop]

@gohan As described above, there was no connection between serial gateway on RPi und sensor nodes.
Above is the whole setup described. Wiring is taken from the mysensors web site.

[gohan]

I am referring to create an ethernet gw running on the RPI instead of a serial gw.

[alop]

@gohan I do not have ethernet hardware. I just wanted to connect radio directly to RPI

[gohan]

Just follow the guide of raspberry gateway and choose to configure it as ethernet, it makes it easier to setup con controller.

[alop]

@gohan said in Raspberry Gateway + Arduino pro mini (atmega328p) NRF24L01 (without plus +):

choose to configure it as ethernet, .

But if I understand right, I need ethernet gateway hardware, or am I missing something?

[gohan]

The RPI becomes an ethernet gateway.
