NVS not initialized error

[dennis.kim]

Hi,

Checking BLE execution by running ble_compatibility_test(\examples\bluetooth\bluedroid\ble\ble_compatibility_test) example code with ESP32-WROOM-32U.
When executing the code, an NVS initialization error occurs as shown below.

Please guide me on how to solve this error.

I have the same problem

I was able to solve a similar error based on the esp-now example project by adding this in main :

Code: Select all

    // Initialize NVS
    esp_err_t ret = nvs_flash_init();
    if (ret == ESP_ERR_NVS_NO_FREE_PAGES || ret == ESP_ERR_NVS_NEW_VERSION_FOUND) {
        ESP_ERROR_CHECK( nvs_flash_erase() );
        ret = nvs_flash_init();
    }
    ESP_ERROR_CHECK( ret );
