Example

STATIC INT_T __new_version_cb(IN CONST TY_UPGRADE_INFO_S *p_ug_info)
{
    PR_DEBUG("new version callback flag:%d, version:%s, size:%d, msg:%s", p_ug_info->flag, p_ug_info->version, p_ug_info->file_size, p_ug_info->msg);

    if (p_ug_info->flag > 0) {
        PR_DEBUG("new version found, please update");
        OPERATE_RET ret = tuya_dev_upgrade_confirm_report();
        if (ret != OPRT_OK) {
            PR_ERR("tuya_dev_upgrade_confirm_report err:%d", ret);
            return ret;
        }
    } else {
        PR_DEBUG("current version is the latest");
    }

    return OPRT_OK;

}

VOID test_ctrl_center_update()
{
    OPERATE_RET ret = OPRT_OK;

    ret = tuya_dev_upgrade_check_init();
    if (ret != OPRT_OK) {
        PR_ERR("tuya_dev_upgrade_check_init err:%d", ret);
        return;
    }

    ret = tuya_home_ctrl_subscribe_new_version(__new_version_cb);
    if (ret != OPRT_OK) {
        PR_ERR("tuya_home_ctrl_subscribe_new_version err:%d", ret);
        return;
    }

    return;
}

tuya_dev_upgrade_check_init does not have a reentrant mechanism and can only be called once after the program starts. The callback is registered via tuya_home_ctrl_subscribe_new_version.
If tuya_home_ctrl_subscribe_new_version is called multiple times, the callback function passed in the last call takes effect.
