Raspberry pi4 with pico lora, can not access web server

Support
1

I have pi4 and tried to connect to a waveshare Pico-LoRa-SX1262. Install required packages, install meshtasticd, connect GPIOs to pico-lora and edit config.yaml. Pico-lora seems boot up OK but I can not access the web server.

Below are messages displayed in pi4 console (over ssh connection)

Then I try to access web page https://:4444 from my PC (in same local network) and get ERR_EMPTY_RESPONSE
What can I do to make web server work? Or are there other methods I can configure region code/channel, etc. ?

Hello Shasta Yeh,

Haven’t setup a Pi Pico with LoRa module, but judging from the output, you should be able to view something using the format:

http://x.x.x.x:4403

or

https://x.x.x.x:4403

where x.x.x.x is the IP address of the Pi Pico. Check your router’s list of connections to find the correct Pi Pico IP address. Many routers show the basic info at http://192.168.1.254, check your router documentation for details.

Good luck!
