Application Example
-------------------
Two examples are provided in ESP-IDF examples directory:
- `07_nvs_rw_value <https://github.com/espressif/esp-idf/tree/master/examples/07_nvs_rw_value>`_ demostrates how to read and write integer values
- `08_nvs_rw_blob <https://github.com/espressif/esp-idf/tree/master/examples/08_nvs_rw_blob>`_ demostrates how to read and write variable length binary values
