I got two whisper nodes avr communicating perfectly with 868MHz according the sample codes from the library.
Next Step:
Is it possible to connect a whisper node to a Arduino uno wirelessly somehow?
I have a Arduino uno with a Dragino LoRa Shield - 868MHz v1.4. I just tried, but it didn't work (maybe because it's a LoRa-Shield).
I found no example project with code samples (just for ESP32 wich i don't want).
I need a Teensy 3.5 or 3.6 with a RF95 connected to a whisper node in the end (because of some Teensy features i need).
A connection to an Arduino would be a experimental step in that direction for the beginning.
Thanks for any hints in advance.

Hi Andre,

Communication between an RFM69HW and a LoRa radio might not be supported by the Libraries.

The RF69 radio only works with FSK modulation while the RF95 (LoRa) library, for example, the RadioHead library, only implements the support for the LoRa modulation for RF95.

Thanks. I found this difference too meanwhile.
