TxRxBlinky example from RFM69 using STM32F303K8

[ATO]

Hi everyone,

I am trying to send a sample "Hi" message from STM32F303K8 to the other one using RFM69HW, and LowPowerRFM69 library.

Here is my schematic. I tried to make it as close as possible to the example given. 

I am using STM32duino to use Arduino IDE.

I see that the function used to send a message, namely sendWithRetry,  is returning False. I have checked all the HW connections multiple times.

Note that, I see a "Button Pressed" in my console, and green & red toggles each time I press a button. Yellow led is always ON, and waiting for sendWithRetry() return TRUE for blink.

Moreover, I didn't connect DIO pin of RFM69HW for my basic application.

Here is my sender code.

Do you have any suggestion for me? I am really stuck at that point.

Best regards,
Talat
