 Therefore, the new approach, which appears to be compatible with both [[hardware:esp32:start|]] and [[hardware:stm32:start|]], is Bluetooth Low Energy Mesh (BLE Mesh).
+====== Planning ======
+I ask some AI Agents to create a concept for this feature. This is the result of it.
+===== Plan: BLE Mesh System with ESP32S3/H2 and Self-Discovery =====
+A comprehensive BLE Mesh network with ESP32S3 as the control unit and ESP32H2 satellites, supporting global control, individual device control, control unit hot-swapping, and automatic device discovery. The system uses ESP-BLE-MESH based on the Zephyr stack with Vendor Models for extended functionality.
+==== Steps ====
+  - **Establish Basic BLE Mesh Architecture** with ESP32S3 as Provisioner and ESP32H2 as Nodes using the [[https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/esp-ble-mesh/|esp_ble_mesh]] Framework
