python SDK 数据接入驱动开发问题

[hk]

想问下，二次开发驱动启动流程中，__start_stream__接口收到start请求中的config配置是从哪儿来的？我实现的DriverApp该如何去取驱动下绑定的设备信息。

平台驱动配置是这样的

看一下这个示例代码，https://github.com/air-iot/sdk-python-examples/blob/master/driver/main.py

[hk]

按照教程打包驱动，离线上传驱动确定后，没有任何提示信息，搜索也搜索不到。
日志没有任何信息。

.tar包文件内容：

jt808-driver.tar.gz内容：

请帮忙看下是为什么不能上传离线驱动。

发一下 service.yml 的内容

[hk]

驱动已成功上传，但是运行报错

在打包docker后，在本地测试运行没有报错

[hk]

SDK中的 startup.py，没有看到--groupId参数的设置，是SDK版本不同么？

[chenpengchao]

这个是后来添加的参数，把 sdk 升级到 v4.0.6. https://github.com/air-iot/sdk-python-examples/releases

请问下，config.yml文件中的两个host地址具体应该如何填写？

填平台域名，外部无法连接，填127.0.0.1后，驱动启动时连接mqtt_data_sender报错
