I have a setup with a RFM69WH plugged on a Raspberry Pi. the system worked fine for about 2 years. Recently, I noticed the system were not able to transmit data. The data reception still work fine.
I swapped the RFM module with another one and this is able to transmit and receive messages. This leads me to eliminate SW or Raspberry issue.
Is there a way to figure out what went wrong, What could be the source of the issue?
Have you tried to replace to power module? The corruption of PM might affect data transmission as well. I recommend you to do that in case nothing else helps. And btw share the results so i can put it into my work since i'm currently trying to write my research papers. Peace out!
