Description

Hi, I am encountering issues while setting up Meshtastic on my Raspberry Pi 5 with a Waveshare LoRa 433MHz GNSS module. Below is the log output and specific errors I am facing:

`Portduino is starting, HWID=1, VFS root at /root/.portduino/default

The main issues are:

I am receiving warnings about being unable to claim several GPIO pins (GPIO21, GPIO16, GPIO20, GPIO18).
The SX1262 radio is not being detected, resulting in the error “Failed to find SX1262 radio.”
Could someone please help me troubleshoot these issues?

Thank you!

  CS: 21

gpiochip: 4

First thing I see is that "gpiochip" needs to be a subkey of Lora. Add a couple spaces to that line. I bet that's the root issue.

Hi, thanks for quick reply.

I managed to start sudo meshtasticd

and now it looks like it boots, but;

When I go to browser and write the https://localhost or https://myname

It shows UNK device. Can't edit or save the setting on it.
