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

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
 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
 * 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.
