NVS custom partition size : 16 kB Hi, When calling nvs_flash_init_partition on a NVS custom partition at startup, the function returns ESP_ERR_NVS_NOT_ENOUGH_SPACE error. This NVS custom partition is meant to hold only blob data, some of which are written only once and some are written...

nvs是在Flash中存储键值对数据,适合存储小规模的数据,不适合存储大的数据。 写键值对时,key 的最大长度为154个字符, 值支持常用的数据类型, 如: uint8_t int8_t uint16_t int16_t uint32_t int32_t uint64_t int64_t 字符串(以\0结尾)
