Hi, I am using mdf_info_save a group_id, but the group_id seem cannot save to flash and the value become Null after reboot. I am no sure if my code have miss some configuration or the logic is wrong.

I use the following function for saving the group id

Code: Select all

    uint8_t dest_addr[6] = {0x0};
    MDF_LOGI("the groupid have length of %d", groupid_args.groupid->count);
    if (groupid_args.groupid->count) {
        ret = mac_str2hex(groupid_args.groupid->sval[0], dest_addr);
        MDF_ERROR_CHECK(ret == false, ESP_ERR_INVALID_ARG,
                        "The format of the address is incorrect. Please enter the format as xx:xx:xx:xx:xx:xx");
    }

    //groupid_cmd_handler(dest_addr);
    ret = esp_mesh_set_group_id((mesh_addr_t *)dest_addr, 1);
    ret = mdf_info_save("group_id", (mesh_addr_t *)dest_addr, sizeof(mesh_addr_t));

and using the follow to load the group id

Code: Select all

    groupid_args.groupid        = arg_str0("s", "send", "<addr (xx:xx:xx:xx:xx:xx)>", "delete the group id of the node");
    groupid_args.end            = arg_end(1);


    const esp_console_cmd_t cmd = {
        .command = "groupid_del",
        .help = "delete the node group id",
        .hint = NULL,
        .func = &delete_groupid_func,
        .argtable = &groupid_args
    };
    ESP_ERROR_CHECK(esp_console_cmd_register(&cmd));

I found that the value seem become null after reboot. Any way to check or suggestion?
