Sender node works / Receiver doesn't

[Mochehe]

Hi,

I am trying a project with RFM69HCW_868MHZ modules,
I will have a network with many nodes and a receiver
There are sensors connected to each node and it transmits theData fine (as shown on the serial monitor) but on the other hand the receiver stops at the comment "listening to 868MHZ" (again, serial monitor),
Every setting has been double checked, ENCRYPTKEY, IS_RFM, Frequency, node id, network id, gateway id, typedef struct - payload, etc.
They are what they should be. It's just I am tired, I did almost everything with the code to make it work but still nothing.
I am using an Arduino UNO board 5v, used voltage divider / Bi directional LLC / connected directly to the Arduino (done it the last as it could burn the module - I have several other modules of the same type that shouldn't be burnt by any chances).
I know it's more a place for Moteino board users but as I'm using this library, I thought it wouldn't be inappropriate to ask for help in here.
I checked the code i'm using with the library's struct_send/recieve example so it could be a lot more like that guaranteed example sketches but still nothing. I'll leave my receiver code in here, please help me if you can, please let me know if the sender code's needed as well. There might be something silly that I'm missing.
Thank you in advance for your time and effort

I suggest you use a board that was built specifically for these radio modules, and not an "Arduino 5V with voltage divider" or some other ProMini. It's not even worth to try and debug why that won't work, too many reasons to mention here.

If you buy a pair of Moteinos with the same type of radio you can be sure will have successful communication and you also support the development of the nice RFM69 library you are planning to use for free.

I understand the must of supporting providers and believe it or not there isn't one single moteino board in my current country (Turkey), I have experienced it before, it'll cost me a hundred dollard to pay for customs clearances to get permission of importing one. Right now I am stuck with normal Arduino boards and don't have an alternative option for this matter. Anyways I would appreciate any suggestions.

In fact I believe there are many Moteinos in Turkey

But I understand your concerns. You may be able to source Moteinos from WELECTRON Germany, or use some other RFM69 based boards that operate at 3.3V.
The radio modules have to be connected/routed to the MCU properly, and have some kind of antenna attached with a GROUND nearby. Breadboard, random length hanging wires across the table will not produce good results. That is why I recommended going with a known working set of boards. In almost every case standard Arduinos connected to radio modules will fail or perform very poorly.

Thanks for the information.
Maybe you've had online shoppers from Turkey that I don't know how they managed the clearance fees!! There is no moteino products for sale in Turkey and that goes the same way about adafruit feather products. Not so popular in Turkey i guess.
I should've thought of these earlier. It would save me a lot of time if HopeRF would mention that these modules must go with special types of dev. boards.
