TLSR8258 zigbee SDK 3.6.0怎么获取云端时间

[jiefengwang]

在zigbee SDK开发过程中，针对入睡计划等需要获取云端时间的，有什么函数接口可以调用？
现在能从网关处获取任务开始时间23：00，持续30分钟

[huanghuan]

1.您可以查看 tal_time_sync.h 文件，使用该函数获取时间

Code: Select all

TIME_T tal_current_time_get(VOID_T);

2.子设备无法直接获取云端时间，需要保证的是，网关已经获取到了云端时间，这时子设备向网关获取时间，网关下发的就是云端时间
3.TLSR8258 zigbee SDK 3.7.1为目前最新开发框架版本，新增了错误码等功能，建议您更新使用，谢谢

TIME_T current_time;
current_time = tal_current_time_get();
TAL_PR_DEBUG("current_time = %d",current_time);

该时间戳是从 2000年1月1日0时0与当前时间的差值，您可参考以下程序：

你好，如果需要新增生物节律、随机定时等DP点功能，3.6.0版本的SDK定时任务底层是不是需要自己实现？我看SDK里面没有相关逻辑。

[huanghuan]

1.生物节律等应用功能， SDK功能不包含此块，协议是公开的，需要应用自己实现
