New to arduino and LoRa,

I'm trying to set up my new rfm95pw on 2 arduinos to make the rx tx test.

Based on the adrafruit example https://learn.adafruit.com/adafruit-rfm69hcw-and-r...ket-padio-breakouts/rfm9x-test

The wiring is based on this:


Tested with the rfm95 everything worked fine.

Tested with the rfm95pw the modules are receiving but not transmitting.

Any help?

First, your links don't work because you did not use the correct posting button.

Second, assuming that you wired them correctly, you cannot receive on one if the other is not transmitting.

And finally, the high power versions need either an attenuator at the antenna connectors or some separation between them to prevent receiver overload.
