Alright,

Sometimes the solution is pretty obvious but you fail to spot it.
@tekka thanks for pointing me to the correct direction, as the problem was in the used frequency.

Even though I initially tried with 434 MHz, it turns out that when i finally did it right, i had already switched to the default 868.
After adding
#define MY_RFM95_FREQUENCY RFM95_434MHZ
in the sketches initially, i established communication.

After that i also tried to configure again the rasperry (this time knowing that the node is working) and Hooray! it worked

Thank you all for your support and @titvs @mfalkvidd as well.

Hi @mfalkvidd , 433 is not defined anywhere (also if you check the link you sent).

Instead, in https://github.com/mysensors/MySensors/blob/master/drivers/RFM95/RFM95.h you can see that the pre-defined symbols are:

// Frequency definitions
#define RFM95_169MHZ (169000000ul) //!< 169 Mhz
#define RFM95_315MHZ (315000000ul) //!< 315 Mhz
#define RFM95_434MHZ (433920000ul) //!< 433.92 Mhz
#define RFM95_868MHZ (868100000ul) //!< 868.1 Mhz
#define RFM95_915MHZ (915000000ul) //!< 915 Mhz

I assume I can override that by setting
#define MY_RFM95_FREQUENCY (433000000ul)

but i also guess that these pre-defined are standards to most hardware devices.
Anyway I will come back once i test these

Hi Both and thanks for your replies.

@titvs I have tried also to assign NODE ID, but without luck. I will try again once i get back to it (i m currently at work so cannot test). EDIT The modules are connected on IRQ pin 2

@tekka Good point. I noticed that the module i use states : 433 MHz only. At some point i did set the frequency to ( #define RFM95_434MHZ ) but i m not sure if i did with the Examples, will certainly give that a shot (i remember i removed to reduce my customisation).
The #define RFM95_434MHZ should be equivalent with what is stated as 433 MHz, right? Could there be a problem?

My apologies, the correct module is : https://www.adafruit.com/product/3073 (and not 3072 as i wrote on my initial post )

Thank you, I will come with an update later today

Hi all,

I am new to MySensors and I have tried to set up a GW with a Sensor to establish communication among the two without success.

I am using Adafruit RFM95 modules ( https://www.adafruit.com/product/3072 ) which I have managed to use with RadioHead library (so i know both modules are functional).

Trying to move over to MySensors, I initially tried to set up a Raspberry Pi Gateway following all the steps of the tutorial, on a serial gw, which (at least and according to the debug info was successful as suggested by the tutorial) and then connected an Arduino Uno according to https://www.mysensors.org/build/connect_radio#rfm6995-&-arduino , using the unmodified example of Mysensors (PingPongSensor as well as a few others).

Notice that i have been using unmodified (default) options, aka. only turning on the RF95 option (through the ./configure on RPi and #define MY_RADIO_RFM95 on arduino, an leaving everything else to its defaults.

My Sensor verbose on the serial is :

.... (and so on)

Apparently, the FPAR fails, so after digging a bit on the forums, people suggested that there is no communication with the GW. In order to avoid having a defective configuration on the gw, i tried to set up a serial gateway on a 2nd Arduino. Again, i got successful verbose :

0;255;3;0;9;32 MCO:BGN:STP
0;255;3;0;9;38 MCO:BGN:INIT OK,TSP=1

And the GW get no recv messages.

In all my cases the sketches are the default ones, with the only change of:
#define MY_RADIO_RFM95
#define MY_DEBUG_VERBOSE_RFM95

(similarly was in the RPi Gateway)

I am also attaching 2 photos of my arduino wirings with the LoRA modules:

I have tried to move on with this communication a few days now and have reached a point where I dont know what to try next. Please suggest where would the problem lie in.

Thank you in advance
