网关sdk开发问题

[15905600423]

参考文档增加子设备心跳功能，直接报错:tuya_iot_fresh_dev_hb op_ret:-1

[Kyson]

请提供一下SDK的日志，这个报错一般是网关还没初始化，请确保在 tuya_iot_sdk_start 之后调用。

这是我们目前使用的sdk 没看到有这个函数啊

[Kyson]

这不是 TuyaOS 的 SDK，有 tuya_user_svc_start 这个接口吧？或者代码提供下，你在哪里调用刷新心跳的

[15905600423]

我们用的应该是联网sdk

[15905600423]

这个sdk用的可能有两三年了？跟版本是否有关系？

[Kyson]

SDK 是很老了，但这功能应该是没问题的，你可以把你调用涂鸦接口的大致示例代码提供下。

[15905600423]

接口调用代码如下

[Kyson]

主要是前面，SDK 初始化的逻辑。在调用刷新心跳之前，调用了哪些接口。
