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

I dont have capacitors on radios.
The distance between radios is 20-30 cm.
Raspberry radio is powered from raspberry.
On Arduino i have additional power supply 5v for the motion sensor.
Arduino is powered through USB.

Am I assuming right, that on raspberry when there is no configure parameter for something, I just change it in MyConfig.h and "make" again?

I had the same hardware setup tested with gettingstarted and the communication was established.

@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.

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.
