Error is showing when I am trying to run Example code.
I am using RPi 3 B and LoRa sx1278 rf 433 .
I want to communicate between these two RPi using this LoRa .

raise Exception('Invalid version.')
Exception: Invalid version.
"Exception: Invalid version." means RPi cannot communicate with SX1278 via SPI interface. Mostly due to pins being connected in-correctly.
Or, you can comment out line 96, 97 in "sx127x.py" to see if the problem is fixed.
It has been 4 days since my reply, close this issue now.
