Sure, there is already the KiCAD file including everything to play around with on your own; added a picture of the schematic here for a quick glance without downloading.
Hi, not sure if @Floca get his nodes working, but for me, the problem got fixed with this
#define MY_RF69_IRQ_NUM MY_RF69_IRQ_PIN
as mentioned by @mfalkvidd Thanks!
This is great, thanks!
One suggestion: add a switch mode regulator that can handle 12 or 24 volt DC input. This will allow small sensor devices to hang off a typical bus network having extra pairs for the central power supply.
There are also other solutions that have I2C bus pins on the shield and if you are going to make a battery powered node, I'd suggest to use an I2C sensor as it will be much more battery friendly
Thank you both for your answers.
With so many parameters to play with, it was not easy to understand what was wrong.. But I think I finally got a way do get my hardware working
Here are my findings :
I thought I got RFM73 version of NRF24-like radios. They look like like here and here.
After checking and connecting all VCC and GND together, switch radios and arduinos... I got them suddenly working with Mysensors development librairies, then back to silence without apparent reason...
Indeed like @mark_venn suggested, I went back to stable librairies and try so set a static ID. Worked well... until it went back to silence again !
Then, following @mfalkvidd advice, I realised that flashing the eeprom_clear sketch solved my all my problems !
My summary :
Ensure that your 3.3V power supply is strong enough.
Ensure that your arduino, radios and sensors are sharing the same GND and VCC.
Use development librairies from github
Flash eeprom_clear before flashing your mysensor sketches
Then gatewaySerial and relayActuator should be able to communicate "out of box", mean you'll monitor some lines like this on the gateway serial : 0;255;3;0;9;read: 0-0-0 s=255,c=3,t=15,pt=0,l=2,sg=0:
Thanks again for your help, now I can start to play
