### = Raw LoRa payload (v2)

Forward the raw LoRa payload and port number without decoding.

{% hint style="info" %}
This decoder also decodes [Geolocation and Local Gateway](/kpn-things/getting-started/tutorials/technical-overview/location-data.md) data.
{% endhint %}

The following SenML records can be present, amongst others:

| name    | type   | unit | example                    | description                            |
| ------- | ------ | ---- | -------------------------- | -------------------------------------- |
| payload | string |      | `"4D985C495AC4D8C9682CFD"` | The LoRa hex payload                   |
| port    | number |      | `200`                      | The LoRa port used to send this uplink |

#### Example SenML

{% hint style="info" %}
SenML can be structured in different ways, and we do not guarantee the examples below will look the same as what you will receive on your Destination. To make sure you can handle the SenML optimally, take a look at our documentation about [Understanding and Interpreting SenML Data](/kpn-things/building-blocks/data-processing/thingsml-and-senml/senml/understanding-and-interpreting-senml-data.md).
