    # BLE Mesh Example

    These are modified files to be able to compile the ble_mesh.ino example.
    Note that a compilation error will still occur as the libraries need to be recompiled with [these configs](https://github.com/espressif/esp-idf/blob/master/examples/bluetooth/esp_ble_mesh/ble_mesh_node/onoff_server/sdkconfig.defaults)

    This is based on the [ESP-IDF Example](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/esp-ble-mesh/ble-mesh-index.html#getting-started-with-esp-ble-mesh)
