V3 Migration - devices.yaml not picked up

[vijay-hcl-epl]

Hi all,
I am migrating a device service to EdgeX 3.0 with CSDK 3.0.2. Below is my devices.yaml file which is not picked up after the device service started. I already validated in yaml validator

devices.yaml(sorry not able to put it inside code format)

• name: "candev"
  profileName: "canprofile"
  description: "Example can device"
  labels:
  - can
  - bus
  protocols:
  other: {}
  autoEvents:
  - Interval: 10s
  OnChange: false
  SourceName: can_rdmsg

However below is the devices file in json format which is picked up by the device service

[
{
"name": "candev",
"profileName": "canprofile",
"description": "Example can device",
"labels": [ "can", "bus" ],
"protocols": {
"Counter": { "Index": "3" }
},
"autoEvents":
[
{ "sourceName": "can_rdmsg", "onChange": false, "interval": "10s" }
]
}
]

Could you please let us know how to ensure that the device service picks up devices.yaml file in V3?

Thank You,
Vijay

Indentation in YAML is very important. Also the casing for most items (except Protocol elements) must be camelCase

Try this:

- name: "candev"
  profileName: "canprofile"
  description: "Example can device"
  labels:
    - can
    - bus
  protocols:
    other: {}
  autoEvents:
    - interval: 10s
      onChange: false
      sourceName: can_rdmsg

CSDK currently only supports device files in JSON format. See https://github.com/edgexfoundry/device-sdk-c/blob/b62e37af488d81aa36bc8e7f628d0bcafa679f3c/src/c/service.c#L486-L526.

Thank you @FelixTing and @lenny-intel for the responses. For now I will go ahead with JSON format in V3..
