[ Device-SDK-C ] Please help in understanding a few queries on how services built with C work ?

[M0hanrajp]

Questions:

• How to run edgex with devices that are built using device-sdk-c ?
  • Per example provided from Device Service SDK - Getting Started C SDK it seems hyrbrid work environment is used.
  • What do I need to consider while running applications built on C with edgex ?
• How can I eliminate errors such as Curl failed with code 6(Couldn't resolve host name)
  • Is there any configuration change that I need to do ? based on the already found work-around I don't think it's the actual solution required for running device services that are built using device-sdk-c.
• Why is there no UI update on the nodes in consul UI ? for any device-service.

For example if I run device-random with edgex services:
I can see on localhost:8500, services tab, device-random shows green check.

Now If I check Nodes tab, then I do not see the device-random service running here.

Why is there no service observed on the nodes tab ? is this based on implementation specific ? can I add this functionality using the current device-sdk-c ?

Please help in understanding the above !

Thanks

Wrting custom device-service please use the guide: https://docs.edgexfoundry.org/3.1/microservices/device/sdk/devicesdk-getting-started/GettingStartedSDK-C/

There are a couple of device services that have been open source here: https://docs.edgexfoundry.org/3.1/microservices/device/DeviceService/

The EdgeX device-service is not a device, it is a collector for IoT device/machine.
