Consider to add support for ESP-IDF idf.py *

[lukasMega]

Do you consider to add support for running idf.py (ESP-IDF) ?
https://docs.espressif.com/projects/esp-idf/en/stable/esp32/get-started/index.html

common commands:

source "~/esp-idf/export.sh"
idf.py build
idf.py fullclean
idf.py flash
idf.py flash monitor
...

example output:

For removing old versions of python, xtensa-esp-elf, components use command 'python /Users/lm/.espressif/v6.0.1/esp-idf/tools/idf_tools.py uninstall'
To free up even more space, remove installation packages of those tools.

Done! You can now compile ESP-IDF projects.
Go to the project directory and run:

  idf.py build

[Ahmarrizwan]

I am building an ESP32 project and want to create my own mobile app to control it instead of using apps like Blynk.

Current status:

• ESP32 is working
• I can control an LED using existing apps
• I understand basic ESP32 programming

Goal:

• Build a custom mobile app that can turn an LED ON/OFF via ESP32

What I need:

1. Which approach should I use for communication (WiFi HTTP, WebSocket, or Bluetooth)?
2. How to create a simple Android app for this (tools, framework)?
3. How to connect the app with ESP32 step by step

Constraints:

• I want a free method
• I am a beginner in app development

If possible, provide a simple working example (ESP32 code + app logic).
