Hi, I'm attempting to test my LoRa 95 radios from Adafruit by connecting one pi to each.
I'm using the following program, loaded onto each pi:
This seemed to run fine on my Pi4, but when using my Pi5 for the other radio, I kept getting the error message:
I've tried the following in attempt to remedy it:

- Changing the pin to an empty GPIO pin (GPIO 17 for example)
- Swapping the radios (still issue, must be the pi)
- Swapping out the wires
- Doing a clean raspbian lite install ...three times.
- Ensuring SPI is enabled
- Checking the wiring like a billion times
