我正在尝试my-module在 arm32v7 Raspberry Pi-3 模型上实现一个 python 模块（比如，）。该模块基于resin/rpi-raspbian:stretch (azure-iothub-device-client==1.4.0b0)。我有iothub_clientpython 库，然后在模块内工作正常。但是，当我尝试iotedgectl start在 Pi 中进行部署和执行时，出现以下错误 docker logs -f <my-module>：

现在这持续了几条消息，并且仅在开始之后（永远不会介于两者之间，一旦它稳定下来）。在几次这样的消息超时和错误之后，场景恢复正常，回调确认，我也能够在 IoTHub 中接收消息。结果，我总是错过前 5-10 条消息，并且无法在 IotHub 中看到这些消息。
经过多次故障排除，我认为存在一个一致的问题。该edgeHub模块似乎总是在my-module已经开始发送消息几秒钟后完全初始化。由于edgeHub未完全初始化且未设置 TLS 身份验证和 MQTT 路径，my-module因此丢失了前几条消息。也许这是因为树莓派是一个慢速设备？
我尝试过my-module手动启动，在edgeHub完全初始化后，所有消息都会在这种情况下传送，没有任何问题。
问题：有没有办法等待edgeHub完全初始化然后开始发送消息？更重要的是，这是实际问题还是其他完全是问题的原因？
如果需要更多信息来获取问题上下文，请告诉我。我试图让我的查询保持简洁:)
