Question

LWM2M设备向IOT代理发送数据时遇到问题。设备已成功连接到服务器。

但是，似乎该设备没有在没有帮助提示的情况下向IOT代理发送数据，发送了以下命令： *

curl --request POST \
   --header 'Content-Type: text/plain' \
   --header 'Fiware-Service: workshop' \
   --header 'Fiware-ServicePath: /' \
   --header 'X-Auth-Token: NULL' \
   --data 't|30' \
   -v \
     'http://localhost:4041/iot/d?k=workshop-devices&i=robot1'

*

返回消息： *

* About to connect() to localhost port 4041 (#0)
*   Trying 127.0.0.1...
* Connected to localhost (127.0.0.1) port 4041 (#0)

不确定是否有人了解这里的情况。

您是否遵循https://github.com/telefonicaid/lightweightm2m-iotagent/blob/master/docs/deviceProvisioning.md的步骤？

我之所以这样问，是因为使用LWM2M不可能使用curl命令从设备发送观测值。为此，您需要使用LWM2M客户端。

设备未向LWM2M代理发送数据
