an end device with JoinEUI A840410000000101 and DevEUI *** is already registered as eui-*** in application io-controller-test

Please help to delete data from database

How did you delete the device? Did you make the API calls yourself?

3

Delete it using “delete end device” button in general settings page. I don’t know how to make API calls

4

Not API calls, I deleted the end-device using the website

6

So I indeed see that this device is registered in application io-controller-test. Is that not your application?

No, it is not mine
I register the endnode device_id": "eui-a840417d6183f826-21 to application gauscagdas, then I have delete it 5min later with following json event report.

The original device doesn’t seem to have been created properly.

{
  "name": "end_device.create",
  "time": "2023-02-28T15:10:38.266724661Z",
  "identifiers": [
    {
      "device_ids": {
        "device_id": "eui-a840417d6183f826-21",
        "application_ids": {
          "application_id": "gauscagdas"
        }
      }
    }
  ],
  "context": {

    ]
  },
  "unique_id": "01GTC96NNTMM7K7EHV6V7AWXKE"
}

If you see, there is no device/join EUI here.

How did you create the device? Did you use the device repository to fill the details or did you fill all the details manually?

This is the first time I am using this type of endnode (Dragino-LT22222). I am registering it for the first time.
I registered it as in the attached picture, but it means there is another problem.

I think it’s possible that the original owner of this device did not remove it before selling it to you.

Where do you purchase the device from?

11

The device I got was the manufacturer’s test device. They deleted the old registration, and the problem is solved. Thank you.

Solutions are set on the person that came up with the idea, not the person that implemented it. Adjusted accordingly.
