@sundberg84 thank you again. I'll do like you say

@bjacobse I've seen them, but as @sundberg84 asked me, it's already finished booster, the one linked in mysensors store.
I'm looking something like the one used on Easy/Newbie PCB.

Can I use something like "Conn_01x03_MountingPin" ?

I'm starting kicad, I already have used easy/newbie pcb for my first sensors, but I need to design a board for an existing raingauge not working anymore (used by an old meteo station). I want to keep the mechanical part, and replace the electronical board.

Thank's for your help

Hello

Does somebody have library for dc-dc step up booster please ?

@mfalkvidd Thank you.
I've found that too https://www.mysensors.org/apidocs/RFM69_8h_source.html
It's clearly indicated that DIO0 is IRQ.

So I think with "--my-rfm69-irq-pin=" it will do the job.

I'll test it as soon as i'll receive RFM69.

Thank you again

@mfalkvidd I don't know what DI00 is, and if it's equivalent to IRQ ? If Yes, it's exactly what I need ! Thank you !!! I will test it as soon as I get my RFM69

Here is the pin mapping between RFM69W/NRF24 and Arduino/Raspberry

Arduino mini - NRF24  - RFM69 - Raspberry GW NRF - Raspberry GW RFM 
9            - CE     - N/A   - 22               - N/A
10           - CSN/CS - NSS   - 24               - 24
13           - SCK    - SCK   - 23               - 23
11           - MOSI   - MOSI  - 19               - 19
12           - MISO   - MISO  - 21               - 21
2            - IRQ    - DI00  - 15               - 22

So, the only mismatch breaking pin compatibility (and preventing to use adaptors on the raspberry pi gateway) is on IRQ/DI00. Adaptors wire RFM69 DI00 on NRF24 IRQ pin, but they don't use, by default, the same pin on raspberry, depending the radio type.

@gohan Sorry I miss your answer a few days ago
I don't want to a gateway with both rfm69 and nrf24..

I'm planning to change my nrf24 sensors with rfm69, to have a better transmission distance. My two nodes are outside, and i have communication trouble if i put them where i wanted, specially for my rain gauge.
So I wanted to use those adaptors https://www.openhardware.io/view/16/NRF2RFM69.
I received them, and I'm still waiting RFM69 board to test it.

But as the pinout is not the same between nrf24 and rfm69 on raspberry gateway, I could not use the adaptor on the gateway. So before making a new board for my raspberry, I wanted to know if it's possible to change the default pin configuration, to have exactly the same as nrf24, and use an adaptor on the gateway too.
For that, I "just" need to redefine DIO0 on pin 15 (default is 22). So I wonder if it's possible to do it.

And "bonus question", I'd like to know why pin configuration is not the same between arduino and raspberry. Why pin 15 is not used for DIO0 on raspberry (equivalent to pin 2 on arduino). I'm telling myself it should be a good reason, but I don't get it.

Hello

Here is my last code for my gas meter. If it could help somebody

 * Version 1.0 - Henrik Ekblad
 * Version 1.1 - GizMoCuz
 *
 * DESCRIPTION
 * Use this sensor to measure volume and flow of your house water meter.
 * You need to set the correct pulsefactor of your meter (pulses per m3).
 * The sensor starts by fetching current volume reading from gateway (VAR 1).
 * Reports both volume and flow back to gateway.
 *
 * Unfortunately millis() won't increment when the Arduino is in
 * sleepmode. So we cannot make this sensor sleep if we also want
 * to calculate/report flow.

@mfalkvidd : I think you have to change the condition in if too :

if (batLoop > 1) {

With that, batLoop = 2 when entering in the if (so the 3 values of the array are filled : 0, 1, 2), calculating the average and reseting the batLoop to 0.
If not modify, the array will be set with batArray[3] just before entering the

if (batLoop > 2) {

Other way is to set the batArray size to 4 values, and divide by 4 (I'm actually trying that).

Hello

I think there is a mistake in your code (on github) to mesure battery.
The array have 4 values, but you divide by 3. So you get to high result.

On line 77

Everything else is ok in my case the board works well with 2 battery AA, and 47uF cap (not with 4.7uF) .

Hello

Is it possible to redefine pin used for DI00 with rfm69 (with configure option for example) ?
Indeed, DI00 is on pin 22 on raspberry, and pin 2 on arduino.
But with NRF, pin 2 on arduino is for IRQ, which is connected to pin 15 on raspberry.

So if it was possible to force pin 15 for DI00, we could use adaptator card like this one https://www.mysensors.org/hardware/nrf2rfm69.
