Setting up the SX1262 with Pico 2 W

1

I am setting up a SX1262 LoRa Node Module for Raspberry Pi Pico, LoRaWAN on a Pico 2 W, with the DEV board, I need help or direction to a video on how to set it up and use it for a text chat between two of them. Does this need to be connected to the PI 4 or 5 to set it up and use it?

Hi @DrScott297390,

It might help a little more if we have some more information, could you please tell us:

  • The Dev Board Model?
  • Any additional software or code that you’re using for this project?
  • A Network Diagram of how you intend to set it up?

Here’s a great video that demonstrates how to set up a LoRa communication system using Raspberry Pi Pico boards—perfect for building a simple text chat or “ping-pong” messaging demo between two units: https://youtu.be/XV_J2V2Bvx4

I think you may be missing a little understanding of some of the lora “names/terms”
LoRa is a radio tx/rx protocol. LoraWAN is a management layer that is on top of lora to manage/abstract some parts for a specific purpose.

If you just want a point to point (no 3rd party involved) then basic lora is enough. you can either do this yourself for a point to point or use something like meshtastic that allosws you to use lora for a wider chat system and allows relaying messages.

LoraWAN is a node to server protocoal. i.e. all end nodes send data to a gateway, that gateway then sends to a server (over a network, e.g. internet), that sever then processed the data and passes the message on to its destination.
So for to nodes to chat to each other with lora wan, it will need (at a min)

loraWAN Node → Gateway → Server … some processing … → Gateway → loraWAN Node

if you just need point to point and the two nodes are within range of each other, then you could just use lora
loraNode → loraNode

Thank you for the information, I am going to try this.
Kindest regards

Good morning Jane

I am using the:

Raspberry Pi Pico 2WH (Wireless WiFi, with Headers)
SX1262 LoRa Node Module for Raspberry Pi Pico, LoRaWAN
PiicoDev LiPo Expansion Board for Raspberry Pi Pico

They are stacked together.

Kindest regards

Hi @DrScott297390 ,

This sounds like a fun project! We have attempted this sort of thing in the past using meshtastic, but I am finding conflicting information on the compatibility with the Pico 2W.

Your Pico 2W has an RP2350 chip inside it, while the older, confirmed supported Pico uses the RP2040.

I would follow this Getting Started Guide for Meshtastic on your Pico and see if you can get anywhere with it.

Hope this helps!
