+# Handshake Capture - ESP32-C6 1.47" LCD
+
+Automatic WiFi 4-way handshake capture for Waveshare ESP32-C6-LCD-1.47.
+
+## Features
+
+- **SD card storage**: Saves `.pcap` files to TF card (not SPIFFS)
+- **Auto-deauth**: Aggressive 150ms deauth interval to force handshakes
+- **Display**: Networks in **green** = not captured, **red** = captured
+- **No web interface**: Capture-only device
+- **WPA/WPA2 only**: Skips Open/WEP networks
+- **BSSID cache**: Captured networks stay red across rescans
+
+## Hardware
+
+- Waveshare ESP32-C6-LCD-1.47 (non-touch, ST7789)
+- TF card in onboard slot
+
+## Build & Flash
+
+Requires LVGL and lv_conf from the ESP32-C6-LCD-1.47-Demo:
+
+```bash
+cd "/path/to/4 way handshake"
+arduino-cli compile \
+  -b 'esp32:esp32:esp32c6:PartitionScheme=huge_app' \
+  --build-path /tmp/arduino-build-handshake-c6 \
+  --libraries "ESP32-C6-LCD-1.47-Demo/Arduino/libraries" \
+  handshake-capture-c6
+```
+
+```bash
+arduino-cli upload \
+  -p /dev/cu.usbmodem* \
+  -b 'esp32:esp32:esp32c6:PartitionScheme=huge_app' \
+  --input-dir /tmp/arduino-build-handshake-c6
+```
+
+Use `arduino-cli board list` to find the correct port.
+
+## Flow
+
+1. Boot → scan → display networks (green)
+2. Pick first uncaptured WPA/WPA2 network
+3. Set channel, deauth every 150ms, capture EAPOL
+4. On full handshake → save to SD, mark red, next network
+5. When all done → rescan, repeat
