+
+    When the function :cpp:func:`adc_cali_create_scheme_curve_fitting` returns :c:macro:`ESP_ERR_NOT_SUPPORTED`, this means the calibration scheme required eFuse bits are not correct on your board.
+
+    ESP-IDF provided ADC calibration scheme is based on the values in certain ADC calibration related on-chip eFuse bits. Espressif guarantees that these bits are burnt during module manufacturing, so you don't have to burn these eFuses bits yourself.
