ESP32 Forum

Hello everyone,
I m working on project to build a mesh network using esp32-C6. Approximately 120-150 devices will be used.
I did research and found that thread is recommended for this large number , went through open thread as well.
But i didn't any project on internet that demonstrated how to use thread and build mesh network , though video exist which openthread based border router but without understand how the code works, what the library does and how to integrate in project is not well documentation i feel. I have installed ESP-IDF on vscode , went through example though even it help . Usually i would expect an tutorial like for example to start from scratch like : Library API, how to integrate , what should be the first in setup to be made and how to configure things. Sorry this mind sound bit odd but really didn't a good example that would demonstrate all these. I request if you anyone knows any reference please help me.
Thank you
Best regards,
Vishnu

Problems:

Every example, forum, YouTube video and even Espressif AI only shows CLI-based UDP
No Native API UDP example exists (otUdpOpen, otUdpSend, otUdpReceive) for Arduino ESP32
Using SimpleCLI — incoming UDP messages only appear in Serial Monitor when another command is typed
No example or documentation for basic custom application like a sensor node sending data over UDP(basically sending packet over udp)
No explanation of when to use CLI vs Native API
Same problem exists in both Arduino and ESP-IDF frameworks — As developers i m stuck between both

Where can I find:

A working Native API UDP send/receive example — no CLI?
A simple sensor node example using Thread + UDP?
Documentation explaining CLI vs Native API?
Any information on the UDP receive buffering issue in SimpleCLI?

This issue is also been tracked within Arduino Issue https://github.com/espressif/arduino-esp32/issues/12616
New features for Arduino OpenThread UDP support will be added.
