◆ meshx_nvs_plat_open()

meshx_err_t meshx_nvs_plat_open ( uintptr_t * p_nvs_handle )

Open non-volatile storage with a given namespace from the default partition.

If CONFIG_BLE_MESH_SPECIFIC_PARTITION is not defined, this function will open the namespace from the default partition. Otherwise, it will open the namespace from the MESHX_NVS_PARTITION.

Parameters

[out] p_nvs_handle Pointer to the output variable populated with the opened handle.

Returns

MESHX_SUCCESS if the storage handle was opened successfully
MESHX_ERR_PLAT if p_nvs_handle is NULL
