Hello, this is my first time using WM1302, and I encountered this problem.
I followed the steps from this link: WM1302 Module Setup Guide
When I try to run ../lora_pkt_fwd -c global_conf.json.sx1250.US915, this is the output I get.
I think it about pin i using but i don’t know how to fix that
Thank you
Hi there,
No GPS?
Looks like it’s naging about that i see and not creating the DIR’s for GPIO’s.
What hardware you using? Can you show a Picturre?

You are close, you’ll get it. can you post config file?
Thank you for the reply
I am using a Raspberry Pi 4B.
My problem is related to GPIO, as I can’t create or access directories for it.
Upon further research, I discovered that Raspberry Pi OS Debian 12 (Bookworm) no longer includes sys/class/gpio (reference: Stop using /sys/class/gpio – it’s deprecated – The Good Penguin). Therefore, I need to switch to Raspberry Pi OS Debian 11 (Bullseye) to resolve this issue.
It’s okay now, I am so very thankful for you time.
