# Generic M2M device (with Internet connection)

![Generic M2M device (with Internet connection)](https://portal.kpnthings.com/assets/images/device-types/own-m2m-with-internet.png)

Connect your own M2M Device that communicates over the Internet. Useful when only Device management data is sent to KPN Things. Part of the Device Management + Connectivity only proposition.

* Supported network type(s): `MQTT`,`INTERNET`,`KPNM2M`
* Device Specification ID: `own-m2m-with-internet`
* Device Specification UUID: `cf872c9e-9343-47db-b972-35dc4df340c8`

### › Decoded ThingsML and raw SenML data

* UUID: `c876bac7-c664-4297-a954-2666eb6aae54`
* Description: One decoder to forward raw SenML data and decoded ThingsML data sent by the device.
* Exchange: `decoder.thingsml.json.exchange`

#### Expected SenML outputs

Unknown

### › Decoded ThingsML and raw SenML data (v2)

Decoder that forwards raw SenML data and decoded ThingsML data sent by the device.

#### Example SenML

This is completely dependent on the SenML or ThingsML input and could output almost any SenML. The decoded ThingsML below is just illustrative of what is possible.

```json

    {
        "bn": "urn:dev:DEVEUI:fe782a953c642aeb:",
        "bt": 1693136532.83,

]
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.kpnthings.com/kpn-things/building-blocks/devices/sensors/generic-m2m-device-with-internet-connection.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
