Description
This PR explicitly disables the onboard WS2812 RGB LED (NeoPixel) during CSI collection on ESP32-S3 boards.
The Problem
When compiling the esp32-csi-node firmware using ESP-IDF v5.2, the core Wi-Fi library automatically assumes control of any detected onboard NeoPixel to use as a Wi-Fi status indicator. Because CSI collection generates immense Wi-Fi traffic, this triggers the LED to shine at blinding brightness constantly, drawing unnecessary power and causing a distraction.
The Solution
Added the espressif/led_strip driver (v3.0.0+) to the project components.
Hooked into
app_main
to initialize the RMT peripheral on GPIO 38.
Explicitly command the strip to clear (0,0,0) its latched state right before the Wi-Fi station connects.
Testing
Flashed to an ESP32-S3-WROOM-1 N8R8 board.
Successfully verified the RGB LED clears to black during boot and remains off while throwing UDP CSI frames.
Verified LVGL UI elements continue compounding without interruption.
