@maman Switching to NRF24 worked like a charm first time. node and gateway are communicating and everything is visible in Domoticz.

I will run range test tonight, if Range is ok I will keep the NRF24 as I am loosing the will to live with RFM69 (I'll still try again when I receive my new modules.)

Thanks

@scalz I use 868 Mhz, I soldered antenna (82 mm), trust me there is no dumb question :)

I get what you say, it should work but I cannot figure out what is wrong

@maman I agree, but I am trying to get my project starting to be fair I do not live in a Mansion and my further sensor will be the one in the Garden for the weather station and the Watering system. So maybe the NRF24L01+ will be ok.

I will keep working in parallel on the RFM69, but right now I feel that I am just wasting time and getting nothing achieved.

I have new RFM69 on Order (RFM69HW instead of the RFM69CW I currently have) I am quite hoping that getting to a differet version of the RFM69 will solve the problem...

I am trying a different approach, I order NRF24L01+ to try tonight and see if I am getting better success with different modules...

What I just realized is that neither on the Gateway Debug nor the Node Debug I see the following message :

TSM:RADIO:OK

how do I know that the Arduino or the ESP is communicating or seeing the RFM module ?

OK I tried again, recheck the wiring, move DI0 to GPIO5 and added the following in the sketch of the Gateway

#define MY_RF69_IRQ_PIN 4  // GPIO 4
#define MY_RF69_IRQ_NUM 4
#define MY_RF69_SPI_CS  5  // GPIO 5

Put the RFM69 in a separate power source, added a 100uF capacitor for the radio.

And still the same result.....

I am litteraly loosing my mind, cannot figure out what else to do...

@Fabien I tried yesterday but it doesn't seem to work. I will try again tonight as I did the test in a rush and may have overseen something.

I just thought about something, could it be possible that the RFM69 doesn't get enough power ? I will try with a separate power source tonight to rule out this.

Thx

Hi,

Following @Fabien idea, I tried with a different RF69M module I had spare with a Arduino Pro Mini 3.3V, I also added a Capacitor of 10uF between the 3.3V of Radio and GND. And I still get the same message.... Arrrgggggg

@Fabien understand your point and I may have fried it with the UNO, but I doubt it is the cause as I had exactly the same output with my first build with a Pro mini 3.3v, every pin were 3.3V and the debug looked exactly the same. I tried with the UNO after countless attempts with 3.3V boards. But taking your point I will try again with a different radio module and a 3.3V.

Any other ideas?

@Fabien This is the pinout of my board

I just double check the output from the 3.3V pinout to be sure and I get 3.28V.

Just to say, I was getting the exact same result with a standalone power supply @3.3V.

Thanks

@Fabien I supplied the power from the 3.3V output of the Board not the 5V output, I was very careful about this so I really doubt that I fried the Radio

Sorry I forgot to mention : I am using the version 2.0 of Mysensors, I use Arduino IDE 1.6.13.

I have check the Voltage to the RFM69 and I am getting 3.28V.. and it is quite stable

For the Gateway, the power is a 9 battery step down via a LM1117 and 2 capacitor of 10uF
For the Node, the 3.3V is supplies by the Arduino Board (I have tried with a UNO and a NANO as well)

Hi everyone, I decided to jump into the wonderful world of IOT and decided to do a simple project to start : a Weather Station, and at a starting point : a Temperature and humidity sensor (using DHT22).

The gateway Connection between ESP8266 and RFM69 I followed this Forum topic

RFM69 <-> ESP8266:

DIO0 <-> GPIO4
SCK <-> GPIO14
MOSI <-> GPIO13
MISO <-> GPIO12
CS <-> GPIO15 (AKA NSS)

And of course GND + VCC

For The radio Connection for the sensor node I followed exactly the Mysensors Guide :
Arduino RFM69
GND GND
3.3V VCC
10 NSS
13 SCK
11 MOSI
12 MISO
2 DI00

And DHT22 is connected on Digital PIN3

Now if I look at the debug from the Sensor Node it seems not able to connect to Radio :+1:

It does connect to the WIFI but it seems pretty much it, nothing else is happening.

I am honestly loosing my mind I check 25 times the connections. I tried different RFM69 Modules. I triple check the code, Tried to read about everything I can find but I cannot figure out what is wrong.

Please help...

Thanks
