1、接口更加安全:NVS不直接操作address. 对于终端用户而已, 更加安全。 2、接口使用接近用户习惯,NVS 接口类似于电脑上操作文件一样: 打开文件(nvs_open), 写文件(nvs_set_xxx), 保存文件(nvs_commit), 关闭文件(nvs_close) 打开文件(nvs_open), 读取文件(nvs_get_xxx), 关闭文件(nvs_close) ...
一、简介 非易失性存储 (NVS) 库主要用于在 flash 中存储键值格式的数据。NVS适合存储一些小数据,如果对象占用空间比较大,使用负载均衡的FAT文件系统。如果NVS...

Edit: It's getting past the nvs init and nvs commit functions without error, returning zero and a handle of 1. Returning ESP_ERR_NVS_NOT_FOUND on the nvs_get_str() function only. If it was a nvs_open_mode_t problem I would think it would error before that? Tried PR #6585 [IDF...
