I'm trying to get the raspberry pi 4 working with a rfm95 915mhz transceiver. I have pins and an antenna port soldered to the rfm95. I'm using the example code. Every time I try to set up the transceiver using:
CS = DigitalInOut(board.CE1)
RS = DigitalInOut(board.D25)
spi = busio.SPI(board.SCK, MOSI=board.MOSI, MISO=board.MISO)
rfm9x = adafruit_rfm9x.RFM9x(spi, CS, RS, 915.0)
I get the same error upon attempting to create the RFM9x object:
"Failed to find rfm9x with expected version -- check wiring"
I followed the instructions listed here: https://learn.adafruit.com/lora-and-lor ... spberry-pi
I enabled spi through the config.
I used "sudo pip install adafruit-circuitpython-rfm9x" to get the library
I have double checked the wiring repeatedly.
I used an alternate raspberry pi.
I used an alternate rfm95 transceiver.
I used alternate pins for the CS, RS, and G0 pins.
Nothing is working. I don't know how to test the functionality of the device nor do I know how to directly access the device using C rather than the python library.
Is there any advice anyone can give me?

Your board is an RFM69 not an RFM95 -- Use this guide https://learn.adafruit.com/adafruit-rfm ... -for-rfm69
