# BTHome ESP32 DevKit Basic Example
# Broadcasts internal CPU temperature via BLE using BTHome v2 protocol
# Compatible with Home Assistant's BTHome integration
#
# Board: Generic ESP32 DevKit V1 (most common ESP32 development board)
# This example works out-of-the-box with no external sensors required
