I'm little confused by definition of ESP_ERR_NVS_INVALID_LENGTH error definition. If I understand it right it is raised when target variable is different type or shorter in case of string than saved value in NVS, right? ESP_igrr
版本V5.0.1,我利用了NVS保存了WiFI的密码和账号,但是我发现经常读不成功地。我看了一下例程,我发现例程只是读某一个BYTE的数据,nvs_get_u8 例如这个读BYTE的接口,是正确的。多次读写都容易成功。但是利用 nvs_get_str 这个读字符串,经常读不出来的,会经常报一个错误 (ESP_ERR_NVS_INVALID_LENGTH)。但是...

ESP-C3入门3. NVS非易失性存储使用,官网文档地址删除名称为"nvs"的默认nvs分区。如果分区已经被初始化了,则先要执行反初始化。handle:由nvs_open返回的句柄将任何挂起的更改写入非易失性存储。

certificate and key to be used for secure connection with MQTT. I'm able to provision a board, and it connects successfully to a secured MQTT broker, but, if I modify that example project to write some data to NVS storage, I'm always getting an error 0x1102 (ESP_ERR_NVS_NOT_FOUND)...
是ESP-IDF(Espressif IoT Development Framework)中的一个错误代码,表示在尝试使用 NVS(Non-Volatile Storage)进行读写操作时,存储空间不足。NVS 是 ESP32 和 ESP8266 芯片上用于存储键值对的非易失性存储系统。 1. esp_err_nvs_not_enough_space 错误的含义 当您在 ESP 设备上使用 NVS API 存储数据时,如果...
根据您提供的信息，您在使用ESP32的NVS-BLOB存储12000个字节数据时遇到了问题。错误代码为ESP_ERR_NVS_...
