LoRa RFM95W : Failed to find rfm9x with expected version

Post by thierry922 »

Hello,

I test "Adafruit LoRa Radio Bonnet with OLED - RFM95W @ 915MHz "
with 2 raspberry 4 and 3 ( Pi Os 64bit, python 3)

I install circuitpython with success
https://learn.adafruit.com/circuitpytho ... spberry-pi

Hello blinka!
Digital IO ok!
I2C ok!
SPI ok!
done!

I follow these tutorials and help

viewtopic.php?t=175885
viewtopic.php?p=828348
https://learn.adafruit.com/circuitpytho ... rs-devices

But I have always :

"RFM9x Error: Failed to find rfm9x with expected version -- check wiring"
when I do python3 rfm9x_check.py

Can you help me ?

Can you format another SD card with Pi OS 32-bit lite?

We don't use 64-bit with any of our guides at this time.

Thank you for trying the Lite 32-bit build.

Can you get the board to detect when you change the CS pin from CE0 to CE1?

Code: Select all

CS = DigitalInOut(board.CE1)
based on this thread:

viewtopic.php?t=175885

When did you purchase the RFM95W?

Let's do a replacement. You have already tried many Raspberry Pi models, OS releases and code changes. I have had one issue like this before where replacement resolved it.

Please e-mail [email protected] requesting another rfm95W. They will need your order# and this forum link as authorization.
